Silly Q

Hello,

Bit of a silly question here for most.

If I'm trying to diagnose a dead pc and have no spares. If I was trying to diagnose a faulty mother board or CPU could I take the CPU out from the motherboard and expect the motherboard to beep?

I have a brand new PC in which won't boot, deep anything.

.

Cheers,

Jon

I dont think so. IIRC the CPU initiates the bios so the mobo wont do anything at all without a chip

I thought that may be the case. Worth a shot.

Diagnoses, dead motherboard me thinks.

Cheers

try powering the power supply all by its own to see it it powers, then that could be that out the question,

dissconnect it from everything inside the computer, and pop a paperclip in between the green pin (power on) and any black pin (ground) on the atx P1 20/24 power connecter and plug in the power supply and flick the power switch at the back of the power supply and see if it powers. if it does then you know there is power going to the system.

but for a motherboard you really do need a replacement to see if thats your problem.

also, check the front pannel connectors on the motherboard, the power on switch might have just came loose and needed pushed back in.

Hi Kenny,

Thanks for your suggestions.

I've bascially tried the motherboard and cpu without anything plugged in and recieve a two short beeps and one long beep which pertains to a missing graphics card.

Once the graphics card is inserted the machine does nothing. Its one of two things, the graphics card (likely) or the motherboard. The graphics card has been tried in both pci-e slots too.

Hopefully will get a spare graphics card and test the motherboard.

Cheers,

Jon
