I am having a problem with both of my computers. I built both of them about 3 yrs ago and until now they have been running fine. The problem is they will abruptly crash or freeze up then upon start up, they will either display a frozen splash screen or the black screen with the flashing cursor. At first it would happen once and a while but it is happening more frequently now. It seems like perhaps something is getting too hot cause if I give it some time, it will boot normally. I have speed fan and when i try to monitor the temps, they don't seen unusually hot. Both are identical: Intel core2 duo E8400 300GHz/2 GB of ram/NIVIDIA GeForce GTX 260 Graphics card and a Gigabyte EP45-UD3R motherboard and running XP service pack 3.
