Sorry about that my pc slowed down as i was typing!
Right My PC wouldnt boot up into windows so i took it to a place called "computer assistance" they then said my harddrive was corrupt so i bought a new one from them and they put it in. This is a 500gb harddrive. I then got home to find my pc not working so i bought it back and another problem had occurred. It would not boot into windows again so i took it back under warranty. He said my soundcard had damaged my motherboard somehow and that he would put a motherboard in free for no charge because it had already been in once. So he put an "Asus p5vd2-vm se" into my machine and took the soundcard out. I got home and it worked fine after all that. Now, 3 days later my machine begins to slow down after about 15 minutes, that isnt a precise timing. It usually slows down when im using programs that require more cpu. Then it will slow down and not speed up again if that makes sense. So i restart and go again... When i boot up again it seems to start working fine and then bamm! it starts lagging again!
Sorry about the first post i should've checked before i posted,
Thanks again.
