This is a 0x1A crash and says it's to do with memory, but I still can't hunt it down, but my computer also bombs our V-Ray and rhino which is a pain in the butt, however that behaviour does not BSOD, but this is the only computer that i have ever had that crash's whilst it is in actual sleep mode. I can get busy doing things for my disabled partner and the screen will go from log-on/welcome screen to "no video available" - set by my screen when the pc goes to sleep, and then sometimes you walk past and for some unknown reason the BSOD is there.

Beats me - lol

Could be dodgy RAM or maybe a core on the CPU, or possibly the graphics card and the way windows 7 now uses virtual memory with video memory, all i know is that its a pain.
