Hi, I've encountered this crash around 6 times in the last few days, always when running games: Star Trek Online [through Steam], Neverwinter Nights 2 [through Steam] and Sid Meiers Pirates. I have filled in as many of the system details as I can to the profile - if more are needed, please tell me how to get the information. I also attach reports from CPU-Z, the Minidump and what I can from SF Diag Tool. The most recent changes I have made to my computer are: Defragmentation C drive. Windows 7 defrag. 10 passes. 22/04/12 approx 1400-1800GMT Uninstall multiple games 22/04/12 Install driver for Logitech N305 Wireless NumberPad approx 5/04/12 [This component works correctly] It's been suggested that it may be a fault with the GPU - apparently, the driver from it was last updated 29/07/09. I'd prefer not to fiddle with it until we're sure that that caused the problem, which first arose around a month ago. Many thanks in expectation, I'll get any further info you need as soon as I receive the request, ImperatorAlpha Edit: last date had been incorrectly entered.
