I recently have begun having constant BSODs when playing any games on my system. They just started this weekend, besides an occasional crash here and there in the past. Now, I can't go more than 20-30 minutes of playing any game without it crashing. All of the dmp files seem to point to ntoskrnl.exe. I have tried all sorts of troubleshooting, with the exeption of a full memtest. I ran a quick test and let it run through 2 passthroughs with no errors, I am going to run a full overnight test tonight. The only thing I did before all of the crashes began was to do some cleanup on my system, as I was having audio popping issues with my headphones. So, I uninstalled various audio/video codec packages and video players (DIVX, VLC, etc.). I ran DriverScanner and upgraded all drivers for everything it found, and I have uninstalled and reinstalled my video and sound card drivers. I am attaching all of the logs. EDIT: Just had another BSOD, this time related to nvlddmkm.sys, which I believe has to do with my video card.
