Hoffmaestro Posted December 18, 2012 Share Posted December 18, 2012 Run this command:xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 256 -FileMode Circular && timeout 30 && xperf -d DPC_Interrupt.etlto capture 30s. If you still get the warning, increase the value after buffersize. The pictures tell you have ACPI.sys issue . What is the temperature of your Intel® Core i5-2430M CPU?When I boot my comp and I don't have the high CPU usage issue It's around 40 when idle.Right now when It's supposed to be idle but CPU 0 is at 90% It's at 70 degrees, but thats just because I'm keeping my room like a fridge atm. Otherwise it can go up to 90c.http://www.mediafire.com/?jzzr62p4be76a5fHere is my zipped DPC_Interrupt.etl. Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted December 19, 2012 Author Share Posted December 19, 2012 you have a temperature issue. The CPU seams to throttle to prevent overheating. Set the cooler policy to active (power options), clean the CPU cooler and install the latest BIOS/UEFI. Link to comment Share on other sites More sharing options...
Hoffmaestro Posted December 22, 2012 Share Posted December 22, 2012 you have a temperature issue. The CPU seams to throttle to prevent overheating. Set the cooler policy to active (power options), clean the CPU cooler and install the latest BIOS/UEFI.To me it seems more like overheating is the symptom, not the cause. Since it can stay perfectly cool(around 35-40c) idle for hours, and return to normal temperatures after gaming. This overheating only occurs when the CPU gets stuck at 90% load which doesn't always happen after I play games. Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted December 23, 2012 Author Share Posted December 23, 2012 The throttling only starts when the temperature is too high. Use the gadget from OpenHardware Monitor and monitor the CPU temperature:http://openhardwaremonitor.org/ Link to comment Share on other sites More sharing options...
Kabiaru Posted January 7, 2013 Share Posted January 7, 2013 HI, Am an averge computer "geek". My laptop a Dell Vostro 3550 started freezing some weeks back. I tried to follow the instructions given on this forum/topic but after download of symbols i seem to get lost on what to next. Am using WPA ver 6.2.92 to do the analysis and it does not seem to have the same settings as the one used on this forum. Can anyone help! It has taken me five minutes to do this small write up due to the freezing...... Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted January 7, 2013 Author Share Posted January 7, 2013 zip the file to reduce the size and upload it to your dropbox or SkyDrive account and post a link here. Link to comment Share on other sites More sharing options...
Kabiaru Posted January 8, 2013 Share Posted January 8, 2013 Thanks Magic Andre. The link to the skydrive is Skydrive Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted January 8, 2013 Author Share Posted January 8, 2013 The ip Helper service seems to cause it:If you don't need IPv6 over IPv4, stop the service. Link to comment Share on other sites More sharing options...
Kabiaru Posted January 11, 2013 Share Posted January 11, 2013 I have disabled IPv6 on the wireless network connection using network sharing menus and also through regedit using instructions given on this site Disable IPv6 for Win 7 as i didnt know how uninstall it. However the problem still persists However i have realised that the freezing occurs only when connected to our office wireless network!! If am not connected or if connect using any other wireless network (hotspots for instance), or through my phone the laptop works just fine. Our office connections to the server is through wireless infrastructure and no other computer is experiencing this problem... I have downloaded to skydrive an updated WPR file as still cant figure out how to use it Skydrive 2 p.s. i had to disconnect the wireless to enable me zip file fast enough..

MagicAndre1981 Posted January 11, 2013 Author Share Posted January 11, 2013 Have you stopped the IP Helper Service?This time you have DPC issues cause by the wireless network driver (athrx.sys). Update this driver. Link to comment Share on other sites More sharing options...
Kabiaru Posted January 12, 2013 Share Posted January 12, 2013 Thanks Andre for prompt analysis and response. I cant seem to be able to get an updated driver anywhere. Currently the (Dell Wireless Adapter 1702.802.11b/g/n) is on version 9.2.0.412 of 21/04/2011. Using update driver am informed its the latest though seen somewhere on the net (Pitstop)that there is a new version 9.2.0.496 of 21/03/2012???Please help..By the way IP Help Service is disabled.

MagicAndre1981 Posted January 12, 2013 Author Share Posted January 12, 2013 athrx.sys = Atheros. So get a driver here: http://www.atheros.cz/Look with a hardware diag tool like HWiNFO (http://www.hwinfo.com/) to see which chip the card uses.

Kabiaru Posted January 15, 2013 Share Posted January 15, 2013 Hi..Sorry but am at end wits!! I have down loaded the "latest" driver software for the device but even through manual (i.e. control panel>device manager>properties>update driver software>browse my computer for updated drivers) still returns the message that windows has determined that the driver software is up to date! The current version is 9.2.0.412 whileas the latest driver per Atheros website is 10.0.0.221 for PCI\VEN_168C&DEV_002B&SUBSYS_0205168C Atheros AR9285 802.11b/g/n WiFi Adapter device. downloaded from Atheros..Of course i had unzipped the files first.What can i do next???

MagicAndre1981 Posted January 15, 2013 Author Share Posted January 15, 2013 don't let Windows search for the drivers. select the driver yourself:http://www.eightforums.com/tutorials/9695-driver-install-device-manager-windows-8-a.html Link to comment Share on other sites More sharing options...
