Supervirus

I have some kind of super virus on my computer or something. I cannot log in for more than 30 seconds without it crashing, f11 does not work. Safe mode works for as far asi know. I do not care about any Of the data on there or my installed files or anything g else. I just want to destroy ALL the data on there, even if it means downgrading back to vista.
I have a hp laptop with windows 7 ultimate on it. I bought it a few weeks ago and idk what happened to it. Please help me and don't give me a link to another thread, as I have not seen a solution to this yet.

Well it's kinda annoying because ive subscribed to 3 other websites today and all they gave me were links that didn't help at all

I can't get on the computer to download anything, and if there's too much stress on the computer in safe mode (like notepad) then it will crash. I'm using my iPhone right now so is there a way I can do that from here?

Wow now safe mode just appears in a blue screen with a buncha code on it and the computer crashes

The only friend that I have that lives close has a Macintosh so if it's possible to do it from there il call him up

I don't think he's home. Is there a way to restore my hard drive without a computer?
