Hi. I recently installed vista, and although I do love it, I am getting frequent bluescreens. It seems to happen more when I'm playing a game, but that might be unrelated, or its just related to high CPU usage or something. I get different messages for the bluescreens, the most frequent ones are BAD_POOL_HEADER and IRQL_LESS_OR_NOT_EQUAL. The former first made me think of hard drive error, but they have never had a problem in the past. I switched the power connectors to the hard drives on a hunch, but it solved nothing. The second error makes me think something's wonky with the drivers. I ran two diagnostics- vista memtest (restarts into 16 bit app), no errors found GRC Spinrite, ran twice, both times it gave an error and did not complete. Specs: Windows Vista (64 bit) DFI Lanparty UT nforce 4 Athlon 64 3200+ Geforce 6800GT SB Audigy 1 Logitech Mx518 mouse Logitech G15 Keyboard I am running latest manufacturer provided drivers for all hardware, including Setpoint and the keyboard software. It MIGHT be worth noting that the keyboard profiling software has errored out a few times. In device manager, everything looks fine except for three in 'other devices': -Multimedia Controller -Multimedia Video Controller -Unknown Device All 3 are disabled, and in driver details, it says "no files have been loaded for this device". I assume they can't cause a problem in this state, can they? Here are the .dmp files from my last 5 crashes, I cannot seem to open them, but perhaps they will provide some insight: http://www.megaupload.com/?d=VEWZ12JN Thanks very much for any help, or advice on where to look.
