Hello, I built my computer back in March, and ever since I have been getting BSOD every once in awhile. It mainly occurs when I am either playing a game or rendering a video in Sony Vegas. I don't recall it happening any other time. I'll admit I don't know much about this kind of stuff, so I haven't really been sure what to do. But the main bug check that I have been getting is SYSTEM_THREAD_EXCEPTION_NOT_HANDLED. And the crash address is ntoskrnl.exe+a6622. It does change from time to time though. Also, sometimes it just crashes and the bluescreen doesn't pop up. It just locks up and I have to manually shut down the computer. My friend supplied me with Windows 7 when we put my computer together. So I'm not sure if Windows is causing the problem. I've already tried running memtest86 and I've ran some test on my hard drive, everything seemed to be fine. I have a few files that I can provide from the SF Diagnostic tool. If anyone could maybe check it out for me, I'd really appreciate it. I'll attach my files below. Thanks. Edit- Wasn't aware I couldn't post links. Any suggestions on how I can share my info? Once again thanks for anyone who is able to help me out.
