game, hardware problem?

Hi, 2 out of my 3 games i have installed have started acting strangely. When i start the games the loading screens are all jittery and lots of graphic artifacts i think is the word? all over the place. Lots of colors changing etc. Anyone know whats happening here?

 

make sure your PC meets the minimum requirements for the games, I know its a silly thing to say but you really should check just in case.

In my experience if your getting artifacts when ever you load a graphic intensive program E.G. A game. It often points towards a faulty graphics card.

BUT the first thing I would do is update or reinstall your video card drivers if that fails to work try the game on another machines (family or friends)

If you have a spare card it might be worth testing as well , If none of the above work and your video card is under warranty call who ever takes care of the warranty the place of purchase or the manufacture and talk to them about replacing it or getting it repaired.

This is an explanation of the various faults that can occur with video cards relating to artifacting.

 

because its only started acting, i could suggest overheating as a problem, please post your system specs here as well as the games you are trying to play, download speedfan and check the temps when the computer is under load and watch to see if it goes up as you play, are any crashes occurring?
