Gibberish on the screen during boot

[ZeroBullet]

I've got random gibberish on my screen when I turn my computer on. Everything pre-Windows is still working fine though (BIOS, Safe Mode prompt etc.) in the sense that I can use it, still looks ridiculous.

I can get Windows to load in Safe Mode (although I can barely see what's happening on my screen), but if I try to go in normally the whole system freezes up.
I reinstalled video drivers to no effect.
Tried swapping out ram to see if I maybe had a bad stick, but it's fine.

Any suggestions to try before I go out to buy a new video card to swap in?

edit: I should note that this computer was up and running fine, then I had cause to move it across the room, had the issue start around an hour after I moved it.

Make sure that everything is secured and plugged in correctly. The video card may have come loose or something.
