Of pixels and BSODs

Hello!

I would have liked to choose a more explicit title, but the truth is I'm having a hard time putting this into words.

So I turn on my computer (which was completely cool) and start my favourite video game (Chivalry: medieval warfare, which I have been playing for a while without any problems) and I instantly crash to the desktop. I then retry my game and am rewarded with a very colourful crash: my main display shuts down and my secondary starts displaying colours in a very strange and pixelised pattern.

Every time I restart my computer, the booting up phase is riddled with stray pixels going berserk in random patterns, until I get to the point where I should see my desktop, which is instead replaced with a blue screen which automatically reboots my computer.

I tried opening up my computer. My GPU was pretty dusty so I cleaned it out and replaced it in its slot. All this to no avail.

My GPU is a Diamond ATI Radeon HD4850.
 
PSU: CooloerMaster extreme power 500W
CPU: Intel core 2 duo E8400
MOBO: Asus P5Q turbo
RAM: Corsair xms2 2x2gb
Graphics: Diamond ATI Radeon HD4850
 
Probably not the monitor, since the problem is visible on both monitors.

Anyway to isolate it to my GPU? Any clue as to what may be causing this?
 
Can you try that video card in another computer ? Or try another video card in your computer.. It probably got hot, and messed up a capacitor...
 
@Drivers: The latest for my card, I believe. I have no way of checking.

I tried my friends GPU (same exact one as mine) in my computer and all worked fine. So it's my GPU for certain.. : \
