Hp system restore help

[DevonMK]

I am looking to do a destructive system restore on my computer. I seem to have a big problem with a trojan on my computer that I got off limewire, it has infected system 32 and when i start the computer, it sends hundreds of windows at me, so it is near impossible to do anything before start up.
I have the disks in order to do the restore and I heard that if you press F1 key at the start up screen it will bring you to the BIOS but it doesn't seem to be working, and if I hold F11, it will bring me to a black screen.
I needed to know a possible solution before bringing it to an expert or having to get rid of the entire thing.

Please help.

Try hitting F2, then DEL, you need to set the system to boot from the CD

at the startup screen while it's loading?

Yes the HP discs may be too old. You can purchase a generic Windows XP off-the-shelf disc to get your system back up and running
