i want to see paranormal activity

ye

Basically when i use this video card (9800GX2) all the colour and graphic is very "botched" and the colour is ruined.
i have uploaded a screenshot on what it looks like.

I have tried reinstalling the drivers, including completely removing the old one then installing new ones and also slightling older ones like 183.

I have tried the video card in two computers and on both of them it has the same turnout effect.

Before (two days ago) the computer would fine but when i ran any game such as world of warcraft of call of duty 4,5, the graphics would screw up and colour, then the computer will lock up resulting in blue screen of death and reboot.
But now the computer just looks like it is in the screenshot.

I have used the video card in my computer for about 12 months now with no problems anything near this.

Also my pc specs:
intel q9300
4 GB ram (only 3.5 because xp 32bit)
windows xp 32bit
500 W PSU

the screenshot is from another pc that uses vista, intel i7 and 750w psu
i tried using a HD3450 on my current computer with xp, and everything works fine (well besides i cant play games cos the card is crap lol)
