Tehcnologically Impaired

Here’s the scoop.

My girlfriend’s laptop is fucked. Whenever I start it up, Vista runs something to verify everything’s running smooth, and some other crap. It gets to one point and stops all together, no matter what. Left it go for hours and still nothing.

So it barely boots, can’t get into setup or boot menu, nada.

Personally, I don’t like Vista, and I don’t know anything about laptops.

Is there any way possible I can completely wipe everything and start fresh with the Windows XP Professional disk? Or even Vista if I have to, but anything I can do to fix it and get it running again…?
