About 2 weeks ago i got my new comp. Havent really had time to test out games so really just been using internet. When i installed the driver everything worked except my screen had green pixels all over it, the more i used it, the worse the pixels got. I have a radeon 5870 just wondering if its the driver or the card problem. thanks
You are showing the classic signs of an overheating GPU or an underpowered GPU (insufficient PSU). If you are overclocking the CPU or GPU, return to the default settings and see if that helps. Also, need to know more about your system (type of CPU, motherboard make and model, amount memory, PSU make/model/wattage, etc.
Agreed, installing current drivers is a good idea. My concern is with this statement "the more i used it, the worse the pixels got". These artifacts are generally associated with overheating or inadequate power or both.
