Have an old PC (Athlon X2 64, 4GB, 2 * 250GB , 1 * 640GB , 8400GTS 328GB (I think cant remember))
Has been having problems for a while, - I think heat is the cause for one of the problems though all fans are working, it will either freeze or shutoff if running hot - core temp running indicates this. Have some fans around Ill install at some point - but may be related to the other issue.
Though the problem that is more odd is it will on occasion not start, this last happened about a week ago though worked again the next day - I don't think is temp related. It will power up (LEDs, Fans running PSU CPU and Exhaust fan) but provide no Post beep and no Image to the monitor, (Monitor works).
What are the likley problems? Especially since it is intermitent?
