[bonecollector1]

When i turn on my computer i heard no post beep and i got just a balck screen. I took out the memory no beep. I disconnected all the power connector except the one to power the mobo and no beep either. Any other suggestions or what you think is the promblem? thankz

"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

thankz but how can you test to see if the bios chip is bad?
System: Man: PC Chips
Hard Drive: 80gb
MemoryDR333 PC2700 256mb
processor chip: socket 462
motherboard: SIS 964L
Bios chip: 686 AMBIOS TN64 3177

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

ok i have reset the cmos but i haven't gotten any beep either. I guess the motherboard went dead then

have you tested the PSU with a tester tool AND a multimeter?
