Computer freezes when opening games

[jmlport98]

Ok, so I was installing some mods to Star Wars: Empire at War when I tried to open it and my entire computer locked up. Ran 2 virus scans, nothing(It's a reputable mod from a reputable website, "ueaw"). Try opening Fallout 3, same thing. Tried a system restore, same thing. Tried uninstalling the Star wars game, same thing. Tried opening Starcraft II, made it to the main menu but the same thing. This was last night, figured my graphics card needed a break. Wake up, try again, same thing. Tried resetting my graphics card to the factory clocks, nothing. That's all I got, (not sure if this is revelavent but in the boot menu OS selection after windows 7 it says debugger enabled, "Windows 7 [debugger enabled]", right above Ubuntu, and that's never been there before).

nVidia GeForce GTX 560 Ti

AMD FX-6100

8GB of RAM

Windows 7 Home Premium 64-Bit

This is happening to games I have on Steam and games not on steam, WHAT IS THE PROBLEM, I AM OUT OF IDEAS!!!!


EDIT: Just ran a heavy stress test, working perfectly.

DOUBLE EDIT: Computer crashed about 30 seconds AFTER the stress test was completed.

Try cleaning out our GPU with compressed air. What are your temps like? Your GPU could be dying. Uninstall drivers completely using something like Driver Sweeper and update to the latest catalyst drivers.

The computer freezes due to following reasons
May be graphic card drivers OR directx driver out of date.

Did you install the game patches?
it looks like your main problem is the internet, what connection speed do u use?

So Update the graphic drivers and directx driver from the manufacturer site
