Flickering Screen

Hi everyone.
I've asked dozens of people about this, and nobody has a resolution. I hope you guys do. Because this is VERY irritating.

My screen flickers on and off (1 second intervals) when I play games.
Games like, Bad Company 2, Minecraft, Team Fortress 2, and Mass Effect 2.

It never flickers when I am at the desktop, messing around on the web.

It doesn't turn off, the screen itself turns black and back quickly. It will do this multiple times, sometimes a lot of times consecutively.

Here are some of my system specs:

System

OS - Windows 7 Ultimate, 64-bit
System - Gateway (Model: DX4300)
CPU - AMD Phenom 2, X4 810 Processor (~2.6GHz)

I do not believe this is a heat issue.
My GPU Usually Runs around 30C - 42C

I don't think the screen is dying either.
It's worked fine, besides this.

Any help is appreciated.

 

Has this issue just started after a driver update to your Vid card ?? if so roll back your driver to an earlier version, or vice versa try updating your card to its latest driver here...

No, I've had this problem since December.
And i've rolled back many times.

 

Or if you have a spare Vid card try that also.
