Hello guys, I've been running Windows 7 for the past few weeks now, and i have one issue with one of my drivers which i can't seem to solve. Periodically (intervals ranging from 1 hour - 3 days) my machine gives a BSOD with 'Driver power state failure' Also, if i shutdown the machine (reboot works fine) it never turns of the machine, it stays at the 'Shutting down windows' screen (Not sure if this is related). Another thing is that I had a crashing nvidia driver at one time, at which point it automatically restarted the display driver. I've been fighting with the minidumps and debugging tools for a day now, and somehow it keeps insisting I do not have the correct symbols (even though i downloaded win7 x86 symbols). Also it doesnt seem to do a minidump always when this BSOD occurs. My guess it's probably the nvidia driver causing problems, but i do have a lot of hardware in here, so it might be anything. If somebody could try to analyze the minidump file i attached, and give me some advice i would be really happy . -edit- I found out that in power settings it was set to put the computer to sleep after 30 minutes of inactivity, I have disabled this and am waiting to see if it will still crash.. This just leaves me to find out wich driver causes this problem (even though I do not plan to use sleep mode). With regards, Dave. PS: Here are some system specs Asus P5K mobo Core2Duo E8200 4GB OCZ SLI memory (3,25gb usable because it is x86) Nvidia 8800 GTS 512 MB M-Audio Delta 66 (with the vista driver) 4 sata disks: 36gb WD Raptor 2x 250gb WD Caviar SE16 500gb Samsung spinpoint I hope this information helps a bit.
