Hey, i bought a pc which was ok spec for cs considering how old the game is, it was something like 512 ram, 2.6ghz p4 and a geforce mx440. After a while i decided to upgrade it and bought a gig of new corsair ram and a 6800 GT. I was told that defragging your hard disk would increase your performance, so i did this regularly without knowing that it could damage my hard disk. Ater a while my performance in game started to drop alot and the pc was close to 3 years old without a format etc. I decided to format and this seemed to have solved the problem but after a while my pc started to run really badly and in-game i was getting 80fps in an 800x600 resolution which shouldn't be happening with this pc spec. I thought that it would be to do with my hard disk failing so i purchased a new hard disk and a new motherboard and installed them both.
When i installed windows i used an old DELL sp1 windows xp professional disk that came with my pc when i bought it 3 years ago, but the only thing from dell in my pc was the processor. After a format i installed latest graphics card drivers (also tried earlier versions to see if it made cs run better as it is an old game) and LAN/audio drivers for my motherboard (I lost the disk that came with it). I think that it can't be hardware related as the spec is far too good for problems to occur, but i have to overclock my graphics card/cpu and lower ram timings for the game to actually be playable, which again shouldn't be the case.
I was wondering if anyone has any suggestions as to what could be causing the problems, is it hardware related or do i need to install something else that i forgot after formatting. I'm pretty poor with computer related problems so any suggestions will be appreciated.
Cheers
