You can go to
http://www.ultimatebootcd.com/ and download the file there.
It will boot into most all of the operating systmems there is. That will help you to start up your mashine and then to find out what drivers you will need.
I assume you were new with computers? I am wrong I do appologize. But the UBCD is the best way to boot up your system and fix whats wrong.
As for virtual pc I've never tried it myself though.
There is also Hirams Boot CD that you can easyly find almost all over the net.
Both of them work in a simular way.
I am not really sure though the gravity of your problem. Would you mind elaborate a little bit about that?
