Hello all,

I'm getting a BSOD / system crash (sometimes the PC just quits without a BSOD).

Hardware Specifications

• cpu: i7 920 2666MHz / 8 cores (not OCed afaik)
• mobo: Asus P6T SE
• ram: 2x Corsair CM3X2G1333C9 (64bit DDR3 667MHz)
• gfx: ATI Radeon HD 5970 1GB (XFX HD5970 BE)
• os: Windows 7 Ultimate 64 bit (legit)

All bios, firmware and drivers are all up to date (as of today).

Symptoms

Sometimes the PC runs smoothly, sometimes I get this BSOD. The BSOD always happens when I'm doing something related to graphics, such as viewing a video or playing a game. I get to know about the imminent BSOD ~10 seconds earlier; the PC starts freezing occasionally but increasing in frequency and length of lag (I noticed processor usage in creased from Process Monitor). I've tweaked BIOS settings occasionally but afaik, it was in vain. A day or so ago, I reset it to factory settings.

BSOD contents

The computer has rebooted from a bugcheck. The bugcheck was: 0x00000101 (0x0000000000000019, 0x0000000000000000, 0xfffff88001f35180, 0x0000000000000004).

Important The interesting thing is that although the event log (and BSOD screen) blame a "secondary processor", Windows Action Center sometimes blamed the GFX driver (for the same error).

Also It is interesting to note that after hibernating my PC, I always get the BSOD.
