    "Sounds like a dead BIOS chip..." From the limited description... Power supply or motherboard may be bad. Bios chips fail more from bad attemps of updating or flashing rather than out-of-the-blue

    Replace the motherboard. If the bios chip is bad, this usually means the the motherboard MUST be replaced. Have you tried reseting the CMOS?

    Nice guide Tedster. I really doubt if bonecollector1's PC Chips motherboard has an LED error display. We already know the board gives no beeps. Lets let him report back on the results of the CMOS reset
