Diagnostics for graphics card and motherboard?

by Simon Adebisi - 1/24/10 6:29 PM

Hi all,

I think I have a problem with my nVidia GeForce 8800 GTX.
I was watching a dvd on my computer when suddenly strange artifacts started to appear, and then the whole computer froze up (but the sound kept playing). I switched my computer off.

Now when I start up my computer, strange lines and dots appear on the XP loading screen, and when the desktop should appear, I get white/black/blue bands across the screen, and I can't see the desktop at all.

I can start up in safe mode with no problems.

I tried to install updated drivers but I get an error message saying "The nVidia control panel could not be installed...the most recent driver will be restored". It has now rolled me back to driver version 6.14.10.9794 (dated February 2007).

I have also tried cleaning and resetting the card. I am certain it is not a heat issue, as the hottest it gets is 85 degrees (only on very hot days and when I'm playing the latest games) and the original crash occured while I wasn't playing a game, but watching a dvd. I have not overclocked my card.

I'm assuming the issue is most likely a hardware problem and is either my graphics card or my motherboard. Can anyone recommend diagnostic utilities/tests that I can run to isolate exactly where the problem is occuring?

The computer was bought from Dell just over 2 years ago, and I have not installed or removed any hardware since getting the computer.

Here are my specs:
Intel Core 2 Quad Processor Q6600 (2.4GHz)
Windows XP SP3
2GB RAM
768mb PCIe x 16 nVidia GeForce 8800 GTX

ANY HELP WOULD BE MUCH APPRECIATED!

Thanks,
Simon.
