Why are my screens flickering?

I apologize if this is the wrong category to post this under.

Last night I was playing a game and all three of my screens started flickering and having random horizontal lines on them. On the center monitor (main display) the right half of the screen moved to the left side and the left half moved to the right, it effected the mouse scrolling too. Then the screens went dark, so I rebooted, started memtest and went to sleep. I ran memtest again while I was at class today and did not get any errors either time.

I tried playing the game again and got the flickering and this time a BSOD with a APC_INDEX_MISMATCH error (no number code). Then I checked a different game to see if the flickering still happened and it did. The computer runs fine up until I start a game so I am thinking the problem is with my video card.

Any ideas on how I can prove it's the video card before I go spend money on a new one?

Thanks

Try:
Re-arranging the vga/dvi/hdmi cabes.
Disconnecting the power connectors on the gpu and disconnecting the gpu from the motherboard then reconnecting (If there is any dust inside the gpu, make sure to blow it out).

Hope it works out.
