Guys, sorry it took me so long to answer. I was in the middle of midterms.
First, this computer I'm working on for my roommate (not my own) is seriously messed up. I don't have a basic Windows XP CD to reinstall, as Jiro suggested.
Secondly, I went to Dell's website. I cannot get anything for the Dell Dimension 4700c. Remember, this is my roommate's computer. if you do a search on Dell's site for that, it doesn't give you any support options. Will calling them and asking them for a new restore CD work?
I have tried both F2 and F12 boot and setup options, I cannot get anything to work. This computer is dead and slow as f*ck, seriously. It's enough to piss me off :0
So where do I go from here? I would SOOOO truly appreciate step-by-step instructions since I'm good at that, and everything I've read so far from Dell and etc. has not been in the least bit helpful.
By the way, the Service Tag # is 893M571 and Service Code 24494873293, if that helps anybody any.
