Open your case and make sure that the fan on the graphics card is spinning. Sounds like it might be over heating.

Welcome to Virtual Dr, berty
AMD Athalons run hot fast....
Check if your CPU fan is running and the vanes of the heatsink are not blocked with dust

Please post back if you have success or not with any of the suggestions

yeah i thought it was over heating but the fans are spinning i hope its nothing to do with the omega drivers i installed for the graphics card and i have given it a vacume no dust thankz though

Try blowing a regular house fan directly on the video card. See if that makes a difference. Are you over clocking it by any chance?

Id suggest removing and reseating the graphics card it sounds like it may be creep caused by the heat of extended use.

i did turn it up a little bit with the omega drivers but i dont think im overcooking it at the moment (can they melt?) i will try reseating it and let you know, i will also try regula house fan cooling system, then i'll build a bonfire and get the matches out i am currently working on a design for a november the 5th pc guy hybrid

Bonfires make for terrific smoke signals. You can use that as an alternative to the internet.
If you overclocking, turn the overclocking off and see if that makes a difference.

Edit:
Forgot to add, Welcome to VDr :)

And you can check your temps and voltages with this nice utility, it may or may not give your graphics card temps, depending on the model.

If the temps seem OK, try a different monitor cable.

There is a free Motherboadrd Monitor at this Site
