So even after uninstalling AVG, there's a crash. And yes I updated the video driver and made sure it was for the specific monitor. Now Windows Explorer is crashing with: Faulting application explorer.exe, version 6.0.2900.5512, faulting module duser.dll, version 5.1.2600.5512, fault address 0x00036e8d. And another BSOD: Error code 00000050, parameter1 f805a030, parameter2 00000000, parameter3 804ed4ee, parameter4 00000000. Minidump attached. Has the be a motherboard. The memtest passed 19 times in a row!
