Computer problems

[frawst]

My computer has a trojan virus where as soon as you turn the computer on it shuts down in like 5 seconds. Its a dell with no floppy disk drive and the ctrl + f11 function was deleted or erased because it does not work. I have no xp installation cd because it was built in the pc. If i do a clean installation and delete then recreate a new partition do i need an xp installation cd to reinstall windows or is ther way i can do it from the hardrive?

Borrow a Dell Windows XP CD from someone.
