Hello people, thank you for your answers!
@Gman450 - I've had similar problems in other games yes, In Civilization V I get some sort of glitchy texture in special dialog scenes with other civilizations (I don't know if you know the game). Other than that I've had a bit of troubes in minecraft too with bugging textures.. Allthough these are not legal copies and I've told my self it might be due to a bad crack. BC2 is fully legal and purchased though! I also have some "tearing/glitching/bugging" or whatever it's called when just using my computer for regular stuff.
Heres a screenshot of that for you:

as you (I hope) can see in the picture, theres some tearing in the safari "tabs bar", the windows process line and then a bit on frame on this thread. This graphic bug seems to accelerate when I scroll the mouse but occurs when theres no activity too.
@HEXiT - I havn't overclocked anything about my computer since I'm really not a computer-person-guy, I think of computer parts as the most fragile thing and I don't want to mess with it :-) I have allthough unlocked my CCC - overdrive option to adjust the fan-speed because I confused the activity bar with the fan-speed and though it was at 0% when I looked. I know It's a mess but I did this after the bugs began to occur.
I've checked my heat when playing BC2 and it peaks at about a 82*C, which I think is an awful lot?
I cleaned my whole computer yesterday with an highpower-aircompressor (while of course making sure not to blow up the fan) and there sure was a lot of dust in the graphics card and processor fan. allthough I didn't seem to solve the problem.
About putting it back to stock settings, how do I know if its OC'ed? I didn't change no settings and I think it should be completely stock.
@Swifty_Morgan - I've tried messing with the settings a little bit, if I put VSYNC on another bug occurs that is much worse, something that makes the whole sky area and some other things completely black.
I could try playing a bit more with the settings to make sure..
I have updated my drivers a couple of days ago to the 11.3, so that's unfortunatly not the problem.. I also tried to install a couple of older drivers after advice on another forum, didn't help either so I updated it again.
I don't know if I believe my card should have any trouble handeling it since I ran it about 3 months ago in full settings with no trouble at all.

Again, thanks for the answers everybody..! I appreaciate it :-)
I though about maybe reinstalling my copy of Windows 7 Ultimate, 64-bit. and see if that helped? I might have some virus or corrupted files that affect my computer.. The internet is so smudging.. ;-)
