freezing games

[killuminati96]

ok...

I just got my new RMA'd graphics card & installed it. I also installed a pci case fan to help keep it cool. I installed the newest driver from ATI.com. Games seem to play perfectly with anti-alising etc turned on. The only problem is when I try to turn a game OFF it makes my pc lock up and I have to flip the power switch or save my game & then end it's process in the TaskManager. Any idea why I can't end my games without freezing? lmao!! This is such an ironic problem. I also tried omega drivers but had the same problem. I couldn't install an old driver cuz it gave me an INF Error.

Does it with all games?
What ones?

It seems to do it with pixel shading or just heavy shader games not older games.

Half Life 2
Silent Hill 3
Silent Hill 4

I think Tomb Raider Legends, too. I could exit GTA San Andreas ok tho & Medal of Honor Allied Assault. That game is low shader model tho, something like 1.1. If I only go to the menu and leave it's ok but if I go into the 3D world and then try to leave it freezes. It's fine as long as I'm playing tho.
