Hi!

I have a desktop running Windows XP.

When I turn on the CPU I see the lights on it glowing, but do not receive any display on monitor.

I also checked to see if the monitor display was working by hooking it up to my laptop and it worked fine.

So from that test, am I right to conclude that the problem is in the CPU? And how do I go about correcting this problem? Please help..

Moved from XP to Internal Hardware.

System manufacturer and model?

FWIW: I believe that you are referring to the desktop system when you say "CPU". The CPU is s small but important part of the system.

This is almost definitely a hardware issue. You can open the case and check for any immediately visible problems such as capacitors on the motherboard leaking or bulging. The ones that leak are typically black, cylindrical components near the cooling fan in the middle of the main board.

If you happen to have a motherboard POST tester laying around, or one that you can borrow, that would also be useful.

Less likely components at fault could be your videocard or power supply. Rarely the RAM will cause this as well. If you can test any using another machine, you could narrow things down.

Yes, I am referring to the desktop system unit. Pardon me for any confusion.

The computer is custom-built or custom-made. So, the parts may come from different locations and brands. Anyways, all I see printed on the system unit in front is - Samsung on the CD-ROM drive, X-2008 in mid-right corner, B11S around the top. Should I be looking elsewhere?

No problem :).

Any onscreen error messages or warnings recently?

I will move this from the XP forum to Internal Hardware, where the more knowledgeable can attempt to assist you.

What are the system specs of the computer primarily the Power Supply and Video Card.

Either the video is dead, or the CPU heatsink and fan assembly are caked with dust, and over heating.

Worst case is that the CPU is dead.

@hamluis - No, there is no display on screen whatsoever.

@cryptodan - How do I find the system specs (for power cord, video card, etc.)?

I will attempt to clean the system unit again and then later turn it on to see if that changed anything.

Is this a custom built system or a system like Dell or Gateway?

On the motherboard, I see the name "Mercury". And on the power supply box I see the name "VB11S Switching Power Supply".

Processor is Intel Celeron D.

@Furvy - I do not see any leaks on the motherboard or elsewhere in the system. I do see a few loose wires that are not connected to anything. Not sure if that is a problem or not.

@cryptodan - Yes, this is a custom built system.

@PC Whizzkid - How do I check for hard drive activity?

What I meant was that do you see the hard-drive light flashing or not?

If its a custom built PC you must have an invoice of what came in it?

@PC WhizzKid - Yes, there is a light flashing over the location where the hard drive is placed.

@cryptodan - I am not able to find any document pertaining to the computer at the moment. However, I am still looking for it.

I did clean the system unit again and tried to start it up but still no display. :(

Who built the machine?

Was it you or someone else?

Someone else built the machine, sometime in 2006-07.
