ive got a problem :(

[p3t3r_m]

on my pc numerous different files keep going corrupt in the windows file which stop the pc from booting up ive done a full format and reinstalled windows numerous times with different versions of windows every time one file or another goes corrupt which stops windows from booting up so would this be a hardrive problem or is that hardware or what ?

if you've formated and reinstalled OS's and the problem is continuing to occur is most likely is a hardware issue

Most probably harddrive....

Most probably harddrive....

Thats what I was about to say
you problly have a screwed up HDD

If you have another hd try installing it on that or even anohter os from a usb stick or something and just see if it works fine external hd would be perfect then if it still doesnt work its not hd at least.
