Screen glitches when playing games

As you can see (I hope), my screen shifts to the side, this happens when I'm doing anything that requires some video performance. Also note that if I take a regular screenshot, my screen shows up normal.

I've had this problem before when I overclocked my GPU too much, but then I could just stop it by lowering the values. Now (in my newly built PC [same GPU]) even when I'm not overclocking at all this happens. I have the driver for the GPU installed and everything else seems to be working.

EDIT: Now my computer also completely goes black and the sound gets stuck too, forcing me to restart.

Specs:
- Intel Core i7 2600K CPU @ 3.40GHz (overclocked to 4.20GHz)
- 24GB of RAM
- 64-bit Windows Ultimate
- MOBO is MSI Z77A-G45 gaming
- GPU is an AMD Radeon HD 6800 Series (will be upgrading as soon as I receive my new GPU)

It's the first time I've made a custom build and I've run into some problems, but I have most of them solved so far.

Help would be much appreciated. Sorry if I could've found the answer easily, Google didn't help.

It doesn't have anything to do with alignment on my monitor, the screen changes from time to time and also shows glitchy horizontal lines.
