Recently I have been having many problems with my Windows Vista 64 bit install. Many times when I am flying FSX It will crash and restart (fsx that is). With just about any plane I fly it crashes at some point in the flight. Also I get oom errors every once in a while but usually it just crashes. Also my firefox has stopped keeping me logged in to websites. Usually it keeps me logged in until i clean my cookies but now It logs me out every time i close firefox. I am about to do a clean OS install out of sheer frustration. Shouldnt be hardware failure either. I have Evga 750i FTW mobo, q9550 oc'd to 3.4 ghz, 8 gigs of ddr2 1066 g skill ram,and a gtx 260 ssc edition core 216. If anyone can shed some light on this I would greatly appreciate this.
