need help with winxp reformating urgent

hey guys
to get to the point, when ever i try to reformat i keep on getting a fatal error in the setup part.
A pop up says" Fatal Error - An error has been encountered that prevents setup from continuing. Setup failed to install the product catalogs. This is a fatal error. The setup log files should contain more information." then it tells me to press OK and it restarts and the same problem appears again.

i tried using both of my harddrives to test and it didnt help.

Guys plz help me

are you overclocked at all? is your Windows XP disc in a good condition? IDE cables ok?

dan

no nothing is overclocked becuase i set everything back to normal and yes the ide cables are ok and disc is in good condition

Is some hardware failing?

doesnt seem like it
because it was working perfectly 3 days ago
until i got that virus worm thing and i reformated.

do a fdisk then try it installing it

Clear your cmos, and try it again.
