No display from PC
 

Hello,

My Old Asus PC is showing nothing on the screen. It was working fine then I had the blue screen of death. It rebooted fine, showing the screen, but then shut down again and now I get no display.

How can I tell if it's a software issue or a graphics card problem?

I have a spare graphics card? I've not checked it's got the right connector yet, but if it does will it at least work in a basic set up? Enough for me to know what's wrong or that I need to replace the graphics card.

It's still running XP.

Any help would be much appreciated.

It's not software if you can't get a POST display. If it shut itself down it's probably not the video card. First suspect would be the power supply. Try this:

The PC boots. I can hear it. But I get no display. The thread you directed me too doesn't advise how to check the PSU. I have other graphics cards but they do not fit this PC (they're even older).

How can I check the PSU whether the PSU is failing or the graphics card? Or we're you suggesting it could be the RAM?


The Motherboard is an Asus P5P 800. The Graphics card is an ATI Radeon 9250.

Many thanks for your help.

Hello again.

Just tested graphics card in another old PC and it works. Does that suggest it's the PSU? Can I check that? I'm hoping it's not the MB!

I'm getting no beeps at all. Speaker appears to be connected.

I've not dismantled it yet as it was working fine.

Should I try the taking out the MB battery for 3 mins and reinstall again to flush the CMOS?

Thanks again,

I assume the 9250 is an AGP card? That motherboard also has PCI slots, if you have a PCI video card you can use that to test with.

Remove the video card completely, you should get multiple beeps. Remove the ram completely, you should also get multiple beeps. If you don't, you have a bad PSU, bad mobo, or bad CPU.

Doesn't sound good. I've taken out the AGP card and the RAM and I don't get beeps. How can I determine if it's the PSU, CPU or MObo?

Many thanks,

Only way to tell now is by substitution, and you need to strip it down as per the thread I linked..

The 865PE boards had a known weakness - the Southbridge chip. Inserting and removing USB devices from the front ports would zap it due to static electricity. Open the thing up and examine the Southbridge carefully (top and behind the board) for evidence of burning. Also examine all the standup capacitors on the board for bulging tops and leaking electrolyte.

Much appreciated. Will do, thanks.
