Would be nice if we could, but no there's nothing useful in there. I looked into that when I had a problem with Standby a while ago on a different PC and it wasn't of any help then either!

I have setup an HTPC running MediaPortal with Windows 7 x32 Ultimate, which is set to go to standby after 30 minutes. Sometimes it does and sometimes it doesn't and I can't figure out any rhyme or reason as to why, so I'd be grateful for some assistance with tracking down what the problem is. As you'll know, Windows is pretty terrible regarding providing any information as to what might be preventing standby. I've checked no devices are set to prevent it (of course, if they were it wouldn't work sometimes anyway). If I do powercfg - requests it shows: C:\Users\MediaPortal>powercfg -requests DISPLAY: None. SYSTEM:[DRIVER] \FileSystem\srvnet An active remote client has recently sent requests to this machine. AWAYMODE: None. but I've used the tweak to set "Enable standby with remote opens" in Power Options and powercfg -requestsoverride shows: C:\Users\MediaPortal>powercfg -requestsoverride [SERVICE] [PROCESS] [DRIVER]\FileSystem\srvnet SYSTEM I had LogMeIn installed, which has an option at install to "Prevent standby when AC power is available". I'm not sure how it enforces that, but I unticked it anyway so that shouldn't have been a problem but I've completely uninstalled it now anyway, due to problems with it's mirror driver disabling Aero and not re-enabling it after disconnecting. I now have TightVNC installed which uses a mirror driver but that does re-enable Aero when disconnected. I don't think that can be anything to do with the Standby problem anyway.

Wow, even grub4dos can change the active status of a primary partition without screwing things up I vaguely recall something about not using XP disk management (or even any tools under XP) after creating large partitions in Windows 7, so I'll be avoiding that anyway. Maybe it would be easier to compile a how-to detailing the only SAFE ways to manage disks/partitions, as there's so many pitfalls it would probably be shorter. It seems my approach of doing nothing is probably the safest one, as I can't mess anything up if I don't try anything

Thanks, that's good information to know. Luckily no-one else has access to my PCs and I'm not likely to install a pre-SP3 XP or Windows 2000, but I'll be careful to avoid using any old PE CDs

run this command and do you normal work: xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 256 -FileMode Circular && timeout -1 && xperf -d DPC_Interrupt.etl after you got an glitch, go back to the command prompt and stop it. The -MaxFile 256 -FileMode Circular options limit the size to 256MB. So you can run it longer without generating a large file. OK thanks, I'll try that but as I say it's tricky because I saw problems in LatencyMon when there were no audio/video glitches and then audio/video glitches when there was no problem shown in LatencyMon, so I can only hope that the glitches coincide with a latency problem (I'll have no way to see as I can't run LatencyMon whilst runnign xperf, as you taught me before) and that there's something useful in the .etl for you to see.

Thanks for explaining all that. I'll study it, worry a bit and then probably do nothing about it as I'm too busy and everything's working at the moment anyway I'm not sure why one partition is using the "new" convention and the rest the "old". I might change that since it should be quite easy and I don't really need a triple boot anyway, so can just boot Win7 from P2 if I mess up P3. I boot Windows 7 (mostly) and XP (sometimes) on this system and haven't had any problems with "P5" due to it crossing the 128 Gb LBA28 boundary. What's defrag or CHKDKS? Only kidding, but I don't use them much (I use defraggler sometimes, but mainly for defragging individual files to make them contiguous for grub4dos) and chkdsk only tends to run when the "dirty" flag has been set for some reason, when it tends to have been set for all partitions so having the space divided into smaller partitions wouldn't make chkdsk any quicker. On my other system I do have a separate, 292GB, partition for games (followed by a 1.3TB data partition and two Primary partitions at the start for dual-boot) but I'm always running out of space and having to decide what to delete to install a new game I want to try, so really it's a pain having the space divided although there is the advantage of it being quicker to defrag. What I sometimes try to do is install the games first on a blank data partition, as then they'll be at the start of the drive and unfragmented and this won't change even if the rest of the drive is fragmented. Another idea I've used is to move all the files to another drive before copying back the most important games first, which can often be quicker than defragging the drive. you see, 1024*16*63 is actually 1032192, but 1032192*512 is the 528,482,304 bytes, whilst we know how your disk contains at least 63+7,831,089=7,831,152*512=4,009,549,824 bytes. The MBR CODE is the grub4dos one, so you are expecting it to load directly the grldr and have it load menu.lst, right? This is normally allright (but I personally find it not advised with "pesky" BIOSes), using a more "tested" MBR CODE (and having it "self contained" in the MBR and not - like the grub4dos one spread over the first few sectors) would be IMHO "better", at least initially. So, right now you have just grldr and menu.lst inside the partition, right? Try booting "as is" and report EXACTLY what happens. Then try changing just the 0B to 0E, try booting and report EXACTLY what happens (if different form the previous). OK, I'll hopefully get a chance to try that this weekend and I'll report back after that. I can already tell you what happens when booting as is with 0.4.6a grldr though (with only the CF connected): hd0,0: FAT32 disk error hd0,1 - hd0,3: Invalid or null BIOS: Drive=0x0,H=0,S=0 (fd0): invalid or null Cannot find grldr I was led to understand that the g4d MBR I have on there might be buggy and need updating though. Can you tell from the MBR I uploaded what version is currently on there? I did have the NTLDR MBR on there, which booted to boot.ini but then had problems loading grldr from there, which led me to install the g4d MBR as something to test whilst I had access to the VL400. Depending on what happens, I can always try putting the NTLDR MBR back on and test that again. The ntldr, ntdetect.com and boot.ini files are still on there. As you say, grub4dos is "confused" as 0.4.4 gave: drive 0x80 (LBA): C/H/S=1024/16/63 Sector Count/Size =1032192/512 whilst 0.4.5c gave: drive 0x81(LBA): C/H/S=1943/64/63 Sector Count/Size=7834176/512 (I'd booted from the HDD for this, which is why the CF was 0x81) so we'll see what the current 0.4.6a gives, before and after changing the partition type!

Woops, sorry. Forgot to set the Physical Drive (MBR) in HDDHacker to Drive 2 (I guess I thought it would grab the MBR of the drive for which I'd just grabbed the Bootsector). This should be correct. And a bit off-topic (but you started it ) what have you got against the way my 1TB HDD is partitioned?. It's a triple-boot, so that covers the first three partitions (I normally hide both of the partitions I'm not currently booted from, but I deliberately left one unhidden at the moment to transfer some files). There's actually a 3.91GB P4 which I intended to use for the Swap-file but then changed my mind and then there's P5 which is the 873GB Extended Data partition. 4GB CF Sectors.zip

Fair enough. I've only been doing tests on the Gigabyte system to check that a) there's nothing wrong with the hardware and b) that what I'm trying to achieve actually works on a decent system (and also because I don't have access to the VL400 very often), but I'll refrain from now on to avoid overloading you with information. So to answer your questions: [*]What is your final goal? (like booting what OS from what media on what machine) I want to boot grub4dos and from there choose either Thinstation (which I boot as an ISO at the moment, but eventually I'll boot as vmlinuz/initrd to use it's "fastboot" feature") or XP-Portable. I've encountered some problems booting this from the CF as an IMG with the winvblock driver (XP is very unresponsive/hangs), so I'll probably end up just extracting the files from the IMG to the CF and boot it normally using chainloader +1, which seems to work OK. I actually want to do this on two machines, using the 4GB CF on one and the 16GB on the other, but they're both HP VL400s. Let's concentrate on the 4GB for now anyway. *]How exactly does the VL400 see the chosen card geometry? The BIOS shows the 4GB CF as Secondary Master - IDE Removable, but under the Boot submenu it shows the CF under both HDDs and Removable Devices. Cylinders 7769 Heads 16 Sectors 63 CHS Format 4010MB LBA Format 4010MB Multi-Sector Transfers Disabled LBA Mode Disabled 32 Bit I/O Enabled Transfer Mode FPIO 4 / DMA 2 Ultra DMA Mode Mode 2 [*]How exactly the chosen version of grub4dos (please name it) on the VL400 see the chosen card (please specify which one you chose) geometry? Using grldr v0.4.4: drive 0x80 (LBA): C/H/S=1024/16/63 Sector Count/Size =1032192/512 However, currently I have updated to 0.4.6a so I need to check how that reports the geometry on the VL400. I'm not actually sure which version of the grub4dos MBR I have on there though (I would have installed it with the latest version of BOOTICE I have, which is 06-05-2012), nor how to update it (i've used grubinstgui in the past but unfortunately that doesn't seem to be available for recent versions and it seems to have the MBR hardcoded in the program, rather than being able to install a MBR file contained in the same directory, which would be handy). Perhaps you can suggest which MBR version I should install and a good way to do so (preferably from Windows)? [*]How exactly the chosen card is currently partitioned/formatted? (under which OS with which settings, etc.) After writing the img to it with mkimg, I believe I had to format it which I think I did in my XP Virtualbox. It currently has a single FAT32 partition anyway. I've attached a zip of the requested sectors. 4GB CF Sectors.zip

I went through the process of training Windows 7 Speech Recognition and got my friends to do the same (under separate accounts I created for them) so that they can use it for gaming when they come over. I'm now considering running some games under XP as they might perform better, but I'd rather not have to re-do the Speech training again (or get my friends to do so). I've installed the Speech SDK and got it working in XP. I thought I might be able to just copy the files from the two folders (MSASR and TrainingAudio) from (Windows7):\Users\xxx\AppData\Local\Microsoft\Speech\Files\ to C:\Documents and Settings\Main\Local Settings\Application Data\Microsoft\Speech\Files\ but as far as I can tell they're not being used (at least the recognition is terrible compared to how it was on Windows 7). I've tried with Mic Boost on and off (Windows 7 has a variable boost but I only set it to 10db, which is probably the same as what XP's Mic Boost does). So I'm wondering if there's some trickery/renaming needed to make XP accept the files from Windows 7? Is there some sort of registry flag that makes XP think the training hasn't been done and therefore it will ignore the existing files, or does it use a slightly different naming scheme, so that the Windows 7 files won't be used as they are? I'd also like to try and swap out the training files, depending on which friend is playing, rather than having to close the game and logout and login as a different user. So I've got the files for each friend backed up in a separate folder and could easily make a batch file to delete the files in MSASR and TrainingAudio (under a generic Users\Gaming\ account) and copy over the files from whichever backup folder I want to use, but will this work or does Windows 7 (or XP) name the files differently for each user, such that this idea won't work as the files won't be recognised?

This is what I found with the 16GB CF (formatted with RMPrepUSB). In the BIOS it shows as Secondary Master 15989MB (not IDE Removable as the 4GB CF does) Cylinders 16383 Heads 16 Sectors 63 CHS Format 8455MB LBA Format 15989MB Multi-Sector Transfers Disabled LBA Mode Enabled 32 Bit I/O Enabled Transfer Mode FPIO 4 / DMA 2 Ultra DMA Mode Mode 2 This boots directly to grub4dos 0.4.5b (27-03-2011) and geometry (hd0) shows: drive 0x80 (LBA): C/H/S=1024/255/63, sector count/size=31227840/512. Partion num:0, active, FAT, partition type 0x0C (compared to 0x0B for the HDD and 4GB CF). Even though it boots to grldr, trying to copy files to the 16GB CF in XP (booted from the HDD) results in Windows totally locking up, mouse and all (this is on the VL400, on my Gigabyte system I've been able to copy files to it no problem, using Windows 7 anyway). Looking at the 16GB CF on my Gigabyte PC with BootICE it shows: C/H/S: 1943/255/63 Total Sectors: 31227840; Sector Size: 512 Bytes which is different to what is shown on the VL400, either in the BIOS or from grub4dos. Maybe I should try formatting it to a 16/63 layout as I did for the 4GB card and see if that fixes the problem of it hanging when writing to it? I'm not sure what values I should use with mkimg for this though. For the CF I used the exact size the VL400 bios sees, i.e. 4,009,549,824 bytes, which is calculated by C*H*S*512, which was fine for the 4GB which reported 4010MB both for CHS and LBA, but in the case of the 16GB CF (using the BIOS figures) gives 16383*16*63*512=8,455,200,768 which is around 8GB, not 16GB, so wouldn't this result in only 8GB being visible/usable? Using the BootICE figures gives 1943*255*63*512=15,981,719,040 (15247.36MB) which is more like it (roughly the 14.89 GB that Windows sees), so I could do "mkimg test.img 15981719040 16/63 0C" but that's not the size the VL400 BIOS sees as calculated by C*H*S or even the "LBA Format 15989MB".

jaclaz has been helping me with this problem previously elsewhere, so I'm posting this information mainly in the hope he can continue to help me here, but if anyone else can help please feel free to jump in The problem I'm having is trying to boot (grub4dos) from a 4GB CF on an old HP Vectra VL400. Firstly, checking in the BIOS shows the HDD as Primary Master and the 4GB CF as Secondary Master - IDE Removable, but under the Boot submenu it shows the CF under both HDDs and Removable Devices. The BIOS reports the following for the HDD Cylinders 16383 Heads 16 Sectors 63 CHS Format 8455MB LBA Format 20404MB Multi-Sector Transfers 16 Sectors LBA Mode Enabled 32 bit I/O Enabled Transfer Mode FPIO 4 / DMA 2 Ultra DMA Mode Mode 4 and for the CF: Cylinders 7769 Heads 16 Sectors 63 CHS Format 4010MB LBA Format 4010MB Multi-Sector Transfers Disabled LBA Mode Disabled 32 Bit I/O Enabled Transfer Mode FPIO 4 / DMA 2 Ultra DMA Mode Mode 2 As for G4D and geometry, booting NTLDR from the CF, which loads boot.ini and selecting G4D from there, which loads grldr (v0.4.4) and menu.lst from the HDD (as it can't see them on the CF), "geometry (hd0)" gives drive 0x80 (LBA): C/H/S=1024/16/63 Sector Count/Size =1032192/512 and for the HDD (hd1) drive 0x81 (LBA): C/H/S=1024/255/63 (I note this shows 255/63 whereas the BIOS shows 16/63, which probably isn't important as it boots). I noticed the grldr on the CF was from 2011, so updated it to the latest April 2012 one I had on my USB and now when selecting G4D from the boot.ini menu (whether with the HDD connected or disconnected) I get the following error: "I/O error accessing boot sector file multi(0)disk(0)rdisk(0)partition(1)\BOOTSECT.DOS" which doesn't make much sense to me as it should be looking for grldr, not BOOTSECT.DOS. I then updated the grldr on the HDD to 0.4.5c (17-01-2012) and after booting directly from the HDD, "geometry (hd1)" returns drive 0x81(LBA): C/H/S=1943/64/63 Sector Count/Size=7834176/512 which is very different from the result with grldr 0.4.4, booted via NTLDR/boot.ini on the CF. I also tried changing the data at offset 0xE6 on the 4GB CF to 90909090 but that just caused it to show "Disk error, press any key to restart" when booting. Changed it back again and it booted to NTLDR/boot.ini again. Also tried installing G4D MBR with BOOTICE and updating grldr to 0.4.5b (17-01-2012) and one dated 25-04-2012, both of which gave (without HDD connected): hd0,0: FAT32 disk error hd0,1 - hd0,3: Invalid or null BIOS: Drive=0x0,H=0,S=0 (fd0): invalid or null Cannot find grldr I'll make another post with the results from my 16GB CF to avoid this one getting too long.

I have a PC connected to my TV, which runs Mediaportal and this requires Aero to be enabled. I also RDP into this box using a separate account (user2) to run programs, browse the web, edit video, etc using the RDP patch to allow more than one user to be logged in simultaneously. The problem is, if Aero (or more precisely dwm.exe) is running for more than one user, strange things happen and Java apps won't load, video playback hangs before starting, etc. The workaround I'm using is to create two shortcuts on user2's desktop, one that does "net stop uxsms" and the other that does "net start uxsms" to stop/start Aero (dwm.exe), so that when necessary, user2 can kill Aero and do whatever they need to and then restart it so that Mediaportal and video playback on the TV will work properly. I'll probably also put these in a logon/logoff script for user2, but it's still useful to have the shortcuts on the desktop, so that if I don't want to logoff user2 (so that I can leave a program running processing some files, or just because I want to take a break and go and watch some TV without having to logoff and then logon again later and reload all my programs) I can restart Aero so that Mediaportal will work properly.

I'm having some issues on my HTPC with audio cutouts. It's possible of course that these are caused by signal problems, rather than latency but I am seeing some latency issues when I monitor with LatencyMon. I just tried running Mediaportal in a window with LatencyMon running and experienced one audio glitch but LatencyMon didn't show any problems at that time. Later I did see an issue in LatencyMon but there wasn't any audio/video glitches that I noticed. This makes it rather hard for me to create the .etl log file at the appropriate time as I won't necessarily have any indication that there has been a latency problem. I've uploaded screenshots of LatencyMon from when it showed a problem. This had been running for about 4 minutes, but I'd been running it for 6-10 minutes before this with no problems showing up before I restarted it, so it was maybe 14 minutes before the problem manifested. Whilst the second image shows netbt.sys at the top, at the time the problem happened I think ataport.sys was at the top and netbt.sys only moved there by the time I connected with TightVNC and made the screenshots.

please start a new topic in the forum for your Windows version. Thanks, will do.

Hi MagicAndre1981 I'm not sure this comes within the scope of this thread, so maybe there's another one you'd like me to take this to. The problem I have is Windows NOT going to standby for no apparent reason (Windows seems absolutely terrible at giving the user any useful information about what's preventing standby). It works half the time and then other times just doesn't, so it's not any devices that are preventing standby. If I do powercfg - requests it shows C:\Users\MediaPortal>powercfg -requests DISPLAY: None. SYSTEM: [DRIVER] \FileSystem\srvnet An active remote client has recently sent requests to this machine. AWAYMODE: None. but I've used the tweak to "Enable standby with remote opens" in Power Options and powercfg -requestsoverride shows C:\Users\MediaPortal>powercfg -requestsoverride [SERVICE] [PROCESS] [DRIVER] \FileSystem\srvnet SYSTEM I've got LogMeIn installed, which has an option at install to "Prevent standby when AC power is available". I'm not sure how it enforces that, but I unticked it anyway so that shouldn't be the problem. I also have TightVNC installed and both of these use mirror drivers but I don't think there's any reason why they'd prevent standby.

I'm not sure there are any chipset drivers to install, other than the ones which get installed with Catalyst (12.3). It's a Gigabyte MA780G-UD3H http://www.gigabyte.com/products/product-page.aspx?pid=3004#ov but in the past I've had the same problem with other AMD-based boards, so the problem's not specific to this board. I switched it to AHCI mode from Native IDE yesterday, which I've been doing with all my boards lately, but that didn't help with this problem at all. I didn't think removable drives would be indexed but I'd already disabled Windows Search anyway. Certainly just waiting isn't an option, as I'd would probably take me about a day to read or burn a disc!

I've had this problem ever since I started using Windows 7, on two different PCs, with two or three different brands of DVD drive. The drives work fine in XP on the same PC, but in Windows 7 when I try and access a disc it chugs away like crazy and takes forever to even show the root contents and then takes even longer to show the icons for the files and I have to eject the disc to unfreeze it. When I tried to fix this problem last April I checked the filter drivers, uninstalled Daemon Tools and SPTD, installed Virtualbox in Windows 7 and made an XP Vbox which could access the drives just fine, installed a fresh copy of Win7 into a VHD which also had no problems accessing the drives, uninstalled Avira Antivir, disabled Windows CD Burning, disabled Windows Seach, run the MS Fixit and I dare say a few other things that I've forgotten about. I never thought that the trickiest problem I'd have with Windows 7 would be getting my DVD drives to work, so if anyone can help me get this sorted out I'd be a very happy man.

Yeah, I've just rebooted and tested Hibernate and it works fine now I've made the current C: Active. I think it will be the same fix on my other PC as that's using grub4dos as well. It'll be nice to finally have Sleep and Hibernate working properly, as I've been trying to get them sorted for a few weeks now. It's not so much that grub is the cause though, just that my current C: drive wasn't marked Active (this attribute was assigned to the 1st partition on the HD, which is my other Win7 partition). I'll have to check but I don't think there's a way for grub to set the Active flag on the partition the user selects to boot, so it's a case of choosing which of the two Win7 installs you want to have Hibernate working for and marking that partition Active.

Hi MagicAndre1981 After helping me with my latency problems, perhaps you can help me with my hibernate problems now I couldn't even get sleep/standby (S3) to work until I disabled Hibernate (powercfg -h off) and then it works fine and if I re-enable Hibernate then Sleep stops working again and the display just blanks but it doesn't standby the PC at all. If I try and Hibernate, not much happens at all. Strangely I'm having the same problem on both a Win7 x64 PC and a Win7 x86 PC. I've uploaded the .etl here: http://www.mediafire.com/?yvhntooz4ya477t The summary_hibernation.xml just contains: <suspend time_unit="us" time_precision="us" min_reported="0"> <scenario start="984746" duration="-0" suspend="-0" resumecritical="-0" resume="-0" /> </suspend> I wonder if for some reason the System is unable to write to the hiberfil.sys. That file does exist, I'm just wondering if whatever process dumps the RAM contents to it when Hibernating (or Sleeping with Hybrid Sleep enabled) is having some permissions problem and finding itself unable to do so. It's not possible to check the Owner or Permissions on that file as it just says "The requested security information is either unavailable or can't be displayed" but it says the same for pagefile.sys. I'm not sure if that's working either, as the timestamps show it hasn't changed since 23 March, but I think writing to hiberfil.sys in the root of C: probably requires greater authority than writing to pagefile.sys in the the root of E:. I'm not sure how to check whether pagefile.sys is being written to/currently used or when it was last written to/last used other than the timestamps. EDIT: Ah, seems it could be related to grub4dos and the Windows partition not being Active http://ubuntuforums.org/showthread.php?t=1341694 If the Windows partition has to be Active for Hibernate to work, it seems to make it impossible to have Hibernate work with a dual-boot Win7 system though. I've set my C: (which is the 2nd partition on the HDD, the first is my other Win7 install) to Active now and it shows this in various apps, but not Windows Disk Management so I'll probably have to reboot to update this. Hibernate isn't working yet anyway, so hopefully a reboot will fix it.

Thanks very much for checking the traces. I'm rather grasping at straws here as it's extremely frustrating having such poor performance from a game and I doubt I'll play it unless it's fixed, but I've tried reducing details and tweaking in many other ways (running in a window is said to help some people, but not me) to no avail. I'll try the new catalyst though (I need a new one anyway as 12.1 keeps resetting my deinterlace setting to Automatic, breaking video/TV playback on my PC.

Hi I said I'd be back I've been trying to play Skyrim now and find it unbearably juddery when moving or looking around. I've just done a fresh install of it, so no tweaks or mods. I made three traces under different circumstances and I think they were all much as bad as each other, so I'd be very grateful if you could have a look and see if you can see anything that might be causing this problem. The first trace is without the THX driver installed and with R263 of the HD Audio driver http://www.mediafire.com/?fabugqs8w73bfjv The second trace is with the THX driver installed and all the THX effects disabled http://www.mediafire.com/?y8ttzt6c819acan The third trace is with the HD Audio driver updated to R267, but I disabled the audio device to see if that would help and I killed as much as I could think of (antivirus, firewall, etc) http://www.mediafire.com/?t02s2vw3zyvjgrx

Hey, Unfortunately there's no EAX settings to change in Deus Ex. I haven't had time yet, but I plan to make a trace with a game that does have a setting to disable EAX for you to look at to see if it shows the same problem.

and your AMD Radeon HD 6970 is bored with a resolution of 1280*720 (Why not use 1980*1080? Your Dell ST2220M supports FullHD and the GPU is fast enough). Deus Ex - Human Revolution uses 1 core heavily. But I can see that the Audio service causes 7s spikes (AudioEng.Dll!CAudioProcessor::ProcessEachAPO which calls the audio drivers - MBTHX64.dll/Creative Audio Processing Object Module) every 6s. So try other audio settings in Deus Ex (no EAX and other things) The Realtek High Definition Audio is a cheap chip which is ok, but not the best. Thanks for checking the log. I play most games on my TV, which only supports 720p or 1080i (and it's a CRT so can't properly resolve even 720p I don't think, plus there's the flicker with 1080i). I'll try tweaking the audio settings. It seems to be OK after rebooting, but does stutter a bit from time to time (although that may just be as it's loading data) so perhaps I can get it smoother with different settings. EDIT: Seems there's no audio settings in Deux Ex (other than volumes) so I can't do much there. There is a separate THX TruStudio Pro driver for this motherboard, which just gives effects which I don't want, so I haven't got that installed at the moment as then I have to disable all the effects, prevent it loading at startup, etc. Maybe I'll grab a trace with another game and you can check if that shows the same issue with the Audio service.

Well I've been trying to play a game but found it was very jerky (was OK yesterday and every other time I played it). I made a trace, so maybe you could have a look and see if it shows what was wrong. http://www.mediafire.com/?3pabucq9t4xp1oo

I'm pretty sure I've rebooted since last doing a trace (and I did stop it anyway), but I did xperf -stop just to be sure and got "xperf: error: NT Kernel Logger: The instance name passed was not recognized as valid by a WMI data provider. (0x1069)." I tried shutting down some of the stuff and then it worked, but it's still working now I've restarted it all, so I don't know what was going on! It's still going to be almost impossible for me to know whether I've had DPC/ISR/kernel latency issues without a program running that shows this though. I might notice the odd cut-out in sound or stuttering TV but that could be due to any number of unrelated problems. I'll probably uninstall Comodo and Virtualbox at some point and compare the ndis.sys, netbt.sys and kernel latency without them installed to see if I can confirm they're definitely pushing things higher.
