Hello, A friend suggested I post here, but I've been sort of leaving it as a last resort - since I don't really use the Forums much at all aside from lurking. However, I've run out of options now. I'm experiencing a frequent BSOD. So far, its only happened when playing DayZ and alt-tabbing out to desktop. It doesn't happen every time. Most of the time I can go the entire time without experiencing BSOD. However, its happened enough for it to become sort of a problem. I don't know what information might be needed to help. Here's some stuff, if you need anything else I'll try my best to find it. Specs: CPU - AMD Phenom II GPU - Nvidia GTX 650 Mem - 8GB RAM OS - Windows 7 Professional I also have an SSD with my OS, DayZ, and a few other programs, and an HD with everything else... if that matters. Stop error code: 0X0000003B Crash dump analysis (from WhoCrashed): On Sat 5/16/2015 12:24:36 AM GMT your computer crashed crash dump file: C:\Windows\Minidump\051515-4664-01.dmp This was probably caused by the following module: win32k.sys (win32k+0x22C9ED) Bugcheck code: 0x3B (0xC0000005, 0xFFFFF9600031C9ED, 0xFFFFF88008865140, 0x0) Error: SYSTEM_SERVICE_EXCEPTION file path: C:\Windows\system32\win32k.sys product: Microsoft® Windows® Operating System company: Microsoft Corporation description: Multi-User Win32 Driver Bug check description: This indicates that an exception happened while executing a routine that transitions from non-privileged code to privileged code. This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system that cannot be identified at this time. I have about five crash dump analysis, but they all say the same thing. Things I've tried: Removing/Reinstalling DayZ Running "check for solutions" in Action Center & fixing anything that popped up there (which happened to be outdated USB drivers) Checked & updated all drivers in device manager. Note: I can't really run a recovery or restore. This is a new copy of Windows 7 that I have installed on this machine, and the problems began after installing this. I really don't want to go through reinstalling Win7 again, if possible. That was a battle in its own and took roughly 40 hours. So, hopefully we can avoid this? I dunno. Any help at this point is appreciated. Thanks guys!
