Game freezes after certain amount of time

After I play a game for like… a half hour, the game freezes. I just bought a new MX 420 graphics card for my computer, and this JUST started happening with it. ANY SUGGESTIONS, IDEAS, SAME PROBLEMS!!! HELLLLP!

Sounds like a heat problem.

Try opening your case and placing a regular fan blowing right on your video card.

Now… play for 1/2 hour+ and see if your game freezes.

If it doesn’t, you’ve gotta heat problem.
