Can you get a screen shot(if it does not show in screens, Try to take a picture of it). It does sound like artifacts. This tends to happen when a gpu starts to fail.

Have you checked (if you have it) also the VRam and VRMs temps?, if you dont have it try to lower a bit the speed of the GPU core and VRam, as they sound similar to corruption due heat/overcloking of the GPU.

Think that the 4850 was quite older (and a generate a lot of heat) maybe the thermal compound is deteriorated and/or the fan dont work properly.

If it is a core or memory issue lower the clocks(on both) will work. It may not last forever that way, but can buy some time.

What stress test did you use?

Only on bios and starting screen?, could be an error of the monitor with non native resolutions?

Maybe are you using a Tv as monitor?

Anyway could check if with 1024x768 or 1280x1024 resolutions you get the red dots or lines?
