My laptop has been running slow and files were corrupting so i decided to delete the existing partition and reinstalled Windows Vista. I was hoping that would fix the problems i was having but my computer is still running slow. I've run CCleaner, Ad-aware SE, AVG anti-virus and a disk defrag. I'm wondering if my hard drive is failing. Also programs like AIM freeze up on me but firefox runs smooth as butter. It's as if some tasks use up all of the memory. I hope someone can offer some advice. Thanks
