Hello,

My desktop's display is unusable. It boots as normal, but then regularly freezes for a few seconds, and becomes garbled with font character sized coloured blocks, or lines of thin red dots. These sometimes clear by highlighting the screen area, but eventually get worse and worse until the system crashes.

I've reinstalled drivers/un and re-installed the screen to no avail.

If anyone has any suggestions I'd really appreciate your help. It's a NV Geforce 4000 MX card ( I think)

Thanks

J

Hi Jsmith, welcome to SAF

This issue may have a lot of causes. As an example, I've seen that once related to a corrupted wallpaper changer.

It may also be an overheating issue... you may try to remove your videocard and cleaning dust from the big heatsink on it. Also, clean the card contacts with a soft white rubber and re-seat it.

If there is some overclock utility, check if it's not set to performances beyound it's capabilities.

I suppose you have done that, but if not, download and install the latest nvidia drivers and DirectX9.

Post back with results.

If you download and run Aida32, You might get some details on the video adapter that will help you get the proper driver update.

Look for an updated driver here.

Hi again,

Took out graphics card, no dust on it really. Put it back in and now the machine won't boot up!

Right after power on, I get a disco of multi-coloured ascii characters flashing all across the screen. It won't go any further.

Any ideas now?

Your card is not properly seated or is dead. Try removing and re-seat it again. Be sure that it is fully inserted on the AGP connector.

Have you done this ? (use a soft white rubber to clean the contacts, do not use any metallic thing or chemical product to do that)
