Windows 7: Random BSODs with BCC 50

Random BSODs with BCC 50

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.

Hi Steve and welcome

These crashes were caused by two things Your AVG, and some really old drivers.

I would remove AVG and replace it with Microsoft Security Essentials and update the drivers listed below

Let us know if you need assistance with any of this
