I can confirm what 13th monkey wrote.
Last week my friend experienced exactly the same symptoms. After testing his Radeon 4850 on my rig, we saw identical effect. Colorful dots right from the boot of the computer. Although it didn't turn off, we couldn't install amd drivers (we ran on standard windows 7 drivers).
We bet that either gpu or (more probably) memory was damaged.
Daneel97 you gonna need new graphic card :/

Yeah, my 4870 failed via colorful dots everywhere (mostly purple dots, but only under load). Check your warranty before buying a new card though :)
