Experienced BSODs on Windows 7 this week? UNINSTALL the latest Patch!
My home server doesn't seem to be able to run for half a day without crashing this week so I ran a barrage of RAM/HDD/CPU tests, but everything reported fine.
Searched google and apparently the issue was with the latest security update windows 7 file system driver installed automatically this week.
Uninstalled it and it's been up for about 30 hours or so.
