Lately, I've been experiencing a BSOD with the message "DRIVER_POWER_STATE_FAILURE" whenever my computer tries to go into hibernation mode or attempts to shut down after a long period of use (When it shuts down, the "Shutting down" screen stays stuck for about 10 min, then the BSOD happens). I encountered the same problem in February, but a system restore appeared to fix it. That is, until now. I attempted a new restore last weekend, but to no avail this time. I did a lot of research on the subject, but this problems seems to pop up on lot of different systems, and in a lot of different ways, so I couldn't find anything that fit exactly to my situation. About my computer: -Gateway FX6801, Intel Core i7 CPU, 920 @ 2.67GHz (8 CPUs), 12288MB RAM, Nvidia GE Force GTX 285 graphics card. Factory spec, no new hardware whatsoever. -Running on Windows 7 Home Premium 64 bits (French version) Had previously been running on Vista with same specs until last December. -All drivers appear to be up and running, up to date (I checked thoroughly, no red Xs or any other error message). -Running Norton 360 Premier Edition 4.0 with latest updates. Yeah. I know. Saw a lot of things being said about Norton/Symantec, but this has been a costly (if not ill-advised) purchase and therefore removing it is not an option unless it DEFINITELY is the culprit (or until my subscription is over). Free antiviruses aren't an option either, ever since Norton found a bunch of viruses on old backup DVDs that had been deemed "safe" by the free antivirus on my previous computer. Today's minidump is included below (I don't have any other ones, they appear to have been erased after my latest system restore, and I've been shutting down my computer manually before getting a BSOD in the last few days. I can always wait for the BSOD to happen again and include a few more dumps if needed.) Thank you kindly for any help, this is driving me nuts!
