So press F2 when I start into windows 7? Is that how to get INTO the BIOS? Then when I'm in there, I have no idea how to disable that function... :/ Do you know of another tutorial or guide that can help me? EDIT: Andre, I am using an apple iMac with Bootcamp installed. Thus, I do not have a BIOS. It is using an "EFI". Do you know how I can access this EFI on my windows side? Alternately I could try booting up my Mac side and changing things from there...

Isn't that a little dangerous? Do you know what that particular thing does? What it is being used for? And I don't even know how to disable something in the BIOS. I don't even know how to access the BIOS... :/

Thanks Andre! I don't understand 99.9999% of that stuff... So what do I do?

Hmm... Odd. Before posting my last reply I had checked the thread several times. How did you manage to figure this out MagicAndre? When I had first run through the steps I thought it was the WLAN driver (which I will still update). And how do I disable this HAL.dll thing?? EDIT: I just tried to update the driver for my Atheros WLAN adapter which I thought would help fix it. It says the driver is version "8.0. ...." whereas the one I found on the Internet says it is version "9.2. ..." but it will not allow me to update to this new .cab file (the manual updater says the driver I have is the latest version...).

Alright I have sent you a PM with the download link to the .zip of the DPC_Interrupt.etl file I hope you can help me figure out what is wrong and how I can fix it! Thanks!

I tried to follow what you were saying, but I don't think I was going it right. Anyways, what program should I use to zip it? It is 1.14 gigs... Or if you could upload some screenshots of how to do it, that might also work. EDIT: I got to the CPU Sampling by process Table. http://i.imgur.com/ICWZB.jpg (note: the blacked-out process is an online game and the game client running. This uses the wlan which triggers the hangup issue) I activated the STACK column. Now how do I do the last part you are talking about? "(DPC/ISR, regular) to the left side to sort it."

Hello everyone, I made an account just to view this whole tutorial. I am running win7 on an iMac. I have had NO ISSUE with it for a very long time. About a week ago I started having what I call "hangups" where my computer would stutter and freeze (and the audio would make a sound like HHRRRGG) for one or two seconds. Measuring my latency, I would also get lag spikes. I tried updating my wireless router software, but it did not help. (NOTE: this ONLY happens when I am using the internet. if I am listening to music or watching shows WITHOUT using the wireless internet, the CPU spikes do not happen.) I have followed MagicAndre's tutorial and it has been VERY helpful. However, I am not sure about what exactly I am doing. I am not an expert. Here is a screenshot of the data I found: http://i.imgur.com/aKdQM.jpg (note: when I expand the "ndis.sys" tree, it says "ndisPeriodicReceivesTimer" occupies the next largest time period) It looks like it is a problem with NDIS.sys, which corresponds to what Andre says about needing to update the WLAN drivers. I have the fileversion.txt that Andre mentions. I do not know what the driver name for my WLAN will look like. I do not know where to go to update my WLAN driver either. Any help would be greatly appreciated!
