so i bought an alienware computer from some guy in the newspaper today and it still had all his junk on it. it came as a tower and a keyboard, no CDs or papers or anything. most of the parts aren't the same, he had been upgrading it for the past 3 years. anyway i want to do a system restore back to factory settings and i don't have a cd or know anything about any backups he had made. is there any way to do this without a cd?

What operating system is it running?

Starter, Home Premium, Pro or Ultimate?
32 or 64 bit?
