The problem is EVEN if I want to format laptop and install a fresh install of OS, I have to wait ~5-10min so that it is restarting and then finaly it boots up, so thats what Ive did yesterday, I installed Win7, and I have to say, the problem isnt there anymore, but I prefered Win XP because I could lower clocks of CPU and GPU with NHC, and it is loading a lil faster. There might be a strange thing, do anyone thinks it could be because I used Windows XP "Performance edition" which means its stripped down. Almost pure OS. If this wont work, Ill try an ordinary Win XP thats ~700Mb big, not this that is ~250Mb.

Thank you two for your help and advice!
Apreciated!
