One of my office's pc unable to boot up. I can hear the hard disk is running but after probably 1 minute it stop running. The monitor is showing "Check Signal" when booting up but turn black and the monitor indicator light turn yellow after the harddisk stop running. I'm not able to eject the cd-rom either and is like the whole thing is hanging. Unable to see the startup screen.
The pc is using Ami Bios. I can't hear any beeps during startup. Have checked the beep codes and it refers to either power supply, motherboard or pc speaker problem.
But how do I confirm that this is a motherboard problem?

Thanks

CSY

No post sound , checking signal is monitor self protect. Check ram may have bad stick or more.

First try disconnecting the hard drive and cd-rom and see if you system will make it thru a POST test. If you still get no video pull all cards except the video card. If you have a video card you can trade out, try that next. Next the memory and last the cpu. Dont forget to check the battery. If it is bad the BIOS could end up with some weird setting that locks it up.

Unless you have a dianostic tool to plug in to your computer it would be difficult to check the motherboard
Using a multimeter you can check the power supply voltage,to determine if it is putting out the correct voltage
Check and listen for the cpu fan to see if it is turning,this could be a problem if you have a dust buildup

that means no signal to your monitor..
Check ur VGA card whether the pin is dirty and ur ram..

Change your ram slot and VGA slot if it is PCI...

Most important is clean this two cards pin.

I've change the VGA card and as well as the RAM.
But still unable to resolve the problem. Thanks for your answer.

Before turning your pc make sure all of the periperals are connected properly,,if it is....is your display adapters in good condition,, try to figure it out to make it sure....if your're sure that u'r video card is good, how about the RAM is it OK? if OK try to remove all drives you have and expansion card that you have except the video card (termination method) then test it,
