PLEASE SUPPLY RELEVANT INFORMATION:
Operating System Version: Windows XP
Problem Application Name & Version:N/a
Problem Hardware Make & Model:
Error Messages:None

I recently had a faulty memory chip, which i sent back to the manufacturer and they replaced. When i installed this chip, there was a smell of burning and the computer display wouldn't work at start up.

When the computer is started all that happens is the hard drives start, but there is no display and the monitor displays 'No signal'.

I've tried replacing the memory with a new chip and i've even replaced the motherboard with excatly the same model to attemp to cure the problem, but nothing happens.

I'm thinking that maybe the video card had blown, but am reluctant to replace unless i'm sure.

I'm guessing that the memory chip was faulty and caused something to blow. Does anyone have any idea what might have happened? There are only some many things that could have failed.

Thanks

The best way to check is first try another Monitor...if it works then you know it's your Monitor.
If it doesn't work,then I would be trying another Video card,if it works then you know its your video card...if it doesn't then more damage has been done than you thought.

Thanks Cactus

I've checked the computer with another monitor, but no success. I guess it's time to try another video card.

Any ideas what else may have failed?

I would try your Video Card in another PC you know is up and running...
You can determine that the vid card is ok without actually instally the drivers.
After installing it ,it should boot Default VGA drivers...you'll see it working.
If there's nothing there then you know for sure its your card.
Some pc repair shops will test the card for free if you don't have access to another pc.

Test the card first then we'll dig deeper if the cards ok.

I've not been able to test my video card in another machine, because it's an AGP and my other computer only take PCI cards. However, i did borrow a working PCI video card from a friend and installed it in my machine. Unfortunately this hasn't improved matters and the screen still displays 'no signal'.

I've also tried a different processor chip, but this didn't improve anything.

A friend suggested that although the CD roms are powering up, the motherboard may not be getting power. I'm not sure about this as a LED does light up on the board when you turn the power on.

Although there is no display, it would seem that the computer is not booting up. There isn

Hey,

I'd check around the AGP slot on your mobo to see if there are any burn marks, also have a look inside the slot to see if there are any burn marks in there. Check the gold connectors on your graphics card to see if they are burned as well. If there was a short or something arced then there should be burn marks somewhere.
