My laptop has been acting a bit odd lately as I was suffering from huge frame rate drops which is making my games completely unplayable. I noticed that this problem has also affected older and less demanding games like Splinter Cell 2 where the Frame rate drops from 80 to less than 10 and it stays like that for sometimes for a few seconds and sometimes for minutes. I thought it was happening due to a graphic driver update so I installed the previous version but with no difference.
