Hey, I play some games, such at GunZ, which i used to play, and it worked fine, but I open it now and instead of the game, my whole screen fills with just like a bunch of colors...I know i have at least all the recommended requirements for the game, I have no idea why this happens...if anyone knows what i should do please tell me. There is a screenshot of what happens attatched.

Thanks

[attachment deleted by admin]Try removing and re-seating the Monitor CABLES...
If no luck remove a side panel and make sure the FAN on the vid card is operating...Okay thanks, I'll try it and then post again took off the cables and checked them and the fan...it was running but very covered in dust, I cleaned it and tryed running gunz and still got the same thing...should I turn my pc off and let it cool down and try again or is there anything else i should try?Hey, I just noticed that some of my programs that use more advanced graphics are not WORKING and i checked my graphics card and found the fan throughly covered in dust...I cleaned it off but i was wondering if the graphics card may have overheated? How could I tell, and is there a way to fix it or would i simply have to buy a new one?(NVIDIA GeForce4 MX Graphics Card)

ThanksIf the fan and heatsink were very dusty, then the graphics card may have been damaged by the heat. If it's still acting up, I'd say it's been damaged, which unfortunately is not REALLY fixable.
A newer, faster card should be FAIRLY easy to find and quite cheap though.

Edit: merged two topics.Thanks Mate
