Hard drive wiped out

Question

A virus of some sort got into my system, It wiped out almost everything. I tried reinstalling my xp pro but it would not work. Kept crashing. I finally used killdisk and completely wiped the hard drive. However, the installation program still won't install. Most of the drivers won't load and after skipping a large number of them the system crashes. I suspect there's still a virus in there somewhere either in memory or something with the boot. I boot from the DVD. There's nothing left in the hard drive as far as I can tell.
