So i want to delete everything off of my computer except the operating system and the other necessary components.

I want all of it gone. I dont want a single trace of it.

I have vista ultimate and no cd. Is there any way to do it?

Mods: Hey guys. I understand this should go in a computer section...but honestly, more people look here. I would appreciate it if you didnt move it, but if you gotta, i understand.
Hmm... what have you been up to? *ponders*

The only things I know are to delete your cookies, cache and temp. downloads. That, and going into BiOS and deleting it permanently.

Don't do the last part UNLESS YOU KNOW HOW. You could delete something you need on accident.

This is ALL I know. :(
