Enormous loading time!

[Sharpened]

Thanks for the reply. It worked perfectly, only recently did this problem appear. However, I don't think the problem is related to my hdd because sometime Kb loads normally, very rarely though. I can run a lot of games normally like Bioshock 2 ( which is heavier than Kb ) What do you recommend me to do? My laptop was attacked by some overheat/force shutdown but nothing affected my laptop's performance.
