Faulty mobo in purchased case?

I recently boughtn another LianLi case on eBay which had a mobo attached. The vendor stated that the auction was for the case only as he was not sure whether the mobo worked or not. Of course I accept this.

The mobo is an Asus P4P800-X. I have added the following:
PSU 500w NEW.
Processor bought as new from vendor on eBay who had mistaken speed.
2 x 1 GB RAM bought new from Crucial.

On powering up fans spin and the mobo light is on. I have tried replacing the CR2032 battery twice without improvement.

No boot. Monitor light just blinks. Graphics card taken from another working PC.

Any ideas please?

Thanks in advance.

Duff BIOS possibly? Try clearing the CMOS....no guarantees though.

Thanks OTT_Buzzard. I thought I had cleared the CMOS by replacing the CR2032 batery, leaving a few minutes gap of course. Do I have to switch PC back on and leave a few minutes?

I will try again.

You're probably right, removing the CMOS battery may well have cleared it out.
If there is a jumper setting for 'Clear CMOS' it may be worth a shot.

Unplug mains lead and any other attached lead. Press the power button for 45 seconds.

Connect up and retry.

OK have tried both battery and switch suggestions but still have same problem. Any other ideas please? Is mobo OK if light is on? Should I try double checking processor? Graphics card was working in other PC. If monitor is just (power light) blinking must it be either processor or card?

Is replacement mobo only option left?

Thanks for your comments.

"Is mobo OK if light is on?"

Not necessarily. It does look as if the motherboard is faulty - assuming the processor are OK and compatible with the board.
