Since the screen capture actually shows the problem it is not your monitor.
There are still a few things you can do.
Unplug your computer and hold the power button down for 30 seconds to a minute to drain any residual charge.
Open up the computer and make sure that dust and hair is not clogging the fans or covering components.
Pull out the gfx card and reseat it firmly just in case there is a connection problem.
Update your drivers to the newest versions.
Have you overclocked your card? If so set it to the defaults.
What are your specs? 32 bit? 64 bit? What gfx card do you have? Try searching for your card model and see if others have problems as well.
Are the games that you have problems with simple games or games that challenge the hardware?
Does this problem happen with any game or just Steam games?
