I'm getting random BSODs for the last week with error code 50. I ran memtest overnight and had 20 successful passes to make sure it wasn't bad memory. I also stepped up the voltage to my memory to make sure it wasn't undervolted, but that didn't fix it.
The BSOD is random -- not related to system stress. If I stress my computer with linx/occt/prime95, I don't get BSOD. The times I've gotten it, it occured when I was resuming from screensaver, surfing the web, and once while playing half life 2.
I'm running x64 Windows 7 Enterprise.
I've attached my minidumps. If you need more information let me know. Any help or thoughts are appreciated.
