Well imo i think it might be my monitor cause if i take a screenshot the problem doesnt show on it. Cause screenshots are taken before it reaches the monitor
edit: actually this time i managed to take a screenshot showing the problem. gonna upload it in a min

Dunno if you can see it from there really. But anyway nothing happens when playing or using a full screen application.. so :lame:
ANOTHER EDIT: OH WTH! Now the problem is gone from the screenshot! i guess it IS my monitor? lol.
Anyway im gonna buy a Geforce GT 220 512mb version.. pretty old maybe but i dont have much money for a newer one
