Recently, my father bought a new PC.
So i took the old one so i could experiment with it! Put some linux on that MoFo
But not a day has passed, or i'm allready having trouble..

I installed Ubuntu 11.04 but i had artifacts all over the place!
(wasn't even doing anything yet)
Then installed Linux Mint 11. Same problem but less severe..

What could have caused those artifacts?

These are the specs of my pc: ( i think because we bought it second hand from a guy who assambled it himself)
- CPU Intel Celeron D 3.06GHz
- Intel 865G chipset
- RAM 2x 512MB DDR400
-Graphics Intel 82865G integrated graphics controller (128MB)

this is the motherboard:

I find the specs terrifying but it's bether than nothing at all..
Hope someone can help me point out what the problem is or what i can do to 'cure' it
