This is terrible...Xp pro crash...help?

[Illuminaughty]

Had an svchost.exe hogging cpu while checking processes in
avanced Process Utility and accidentally killed it.

I run XP Pro sp2 on a HP a1100y Asus Grafito mb

Told me "windows needs to close" then blank screen. In system tools I attempted to reactivate said process, then reboot...

Now Win starts - then nothing; blank screen.
Tried "last working" option: nada
Not even safe mode will run. Just a list of driver.sys then frozen..

And I no longer have XP disk <but is legit ver.>

Am I hopeless?
