Ok, I have this friend who just built a new computer with an Epox 8RDA. We have tried switching the ram, PS, and all, but this problem still arises. What happens is randomly, any given time, full load on cpu, or cpu just idle, the computer just shuts off, no warnign what-so-ever, and it starts to beep reapeatedly, forEVER, unless you unplug the computer totally. It is not a heat issue, as in the bios, afte the computer has been on for a while, still says the processor is only at 107(F)....has anyone heard of this before?
