Artifacts

[Creature]

Hi Guys,

I have a wierd one..

On startup my PC is running fine, until I open my internet browser. Then there are some artifacts all over the screen. I have to then start up Call Of Duty (or any other game that uses a bit of processing power) Then it seems like the machine "warms" up and the artifacts go away. If I exit the game and leave the PC alone for a while and then open my browser or the game again the artifacts are back for a while until "warm-up"

This is very strange and I have never seen this before. Specs in sig

I am desperate for help.

Thank you

Dunno but I've seen the option of using hardware (GPU) rendering in IE9, not sure how but maybe related to your problem?

What gpu do you have an are your drivers up to date?

The correct approach is to identify potential error-causing candidates is by checking temperatures, drivers, software updates and windows event logs (probably not in that order).
Also be sure to reset any recent changes you've made to your hardware configuration.

I have the Gigabyte ATI Radeon HD6950 1GB. All my drivers are up to date. Temperatures are normal. Haven't checked the logs yet, but this is a new machine and has been doing this since day one. So very confused

what power supply do you have? Also are you overclocking your card our have you flashed the bios?... Have you tried other driver versions?

I have a 650W Coolermaster PSU and no, no overclocking, no bios flash, nothing. Stock standard See below screenies of what I mean:

In Firefox-

In COD like this for about 20 secs then it goes away -

Hmmm, first thing i would do is download the latest drivers and do a fresh reload.

then if that does not work take the gpu back and get it tested. You could do that first.

Looks like a VRAM-related issue to me. Could be to do with voltage, since cards typically down-clock at idle. Then when you run the game it increases voltage along with the clocks. Perhaps see if you can use MSI afterburner or some other utility to increase the voltage very slightly, and see if it helps.

You'll have to unlock the voltage option in Afterburner's settings before you can tweak the voltage.

I've heard of these kind of issues with like the Gigabyte GTX 560 Ti, where a simple increase in voltage fixed the issue. I think Gigabyte actually gave new firmware for their cards too if I'm not mistaken.

Update: MSI Afterburner only allow you to tweak the Vcore voltage and not the VRAM, and your artifacts looks like RAM related ones.
