It started out by randomly shutting off every so often and I could re-start it and it would run fine for a while. This went on for a couple of days and yesterday it died and wouldnít start again.
I gave the power supply a superficial check and the +3.3v, +5v and +12v supplies are good. I couldnít easily get to the -12v line so I didnít check it.
I have a Thermaltake, Tough Power 850 watt power supply so it should be hefty enough. I guestimate that Iím using about 450 watts so the supply shouldnít be working hard. I suspect that something might have gone south in the motherboard or CPU, but Iím obviously not sure. I am going to pick up a power supply taster today since they donít cost much and are easy to use.
Does anyone have any suggestions, or know what the 1 long and 3 short beeps mean? The motherboard is an ASUS Crosshair (the older one) with an AMD A64 x2 6000 3.0G AM2x1M R CPU. The computer is about 2 1/2 years old.
