I think I broke my computer, please help!

[Mike Harrison]

Sorry if this is in the wrong place, couldn't find a forum for non-FIRST related technical discussion and I really don't know who else to ask, so...

I will try to explain this the best I can as I am near computer illiterate:
My computer plugs into the wall near the floor, this plug is behind some stuff and is normally really loose, as in hanging there barely giving passage to electrons. So I'm on the computer and my cat unplugs the cord as he is extremely intelligent and helpful. I thought this was no problem until when I tried to click on my account (i have windows xp) my cpu reboots and comes back to an HP screen that gives me some options and then continues to go back to the logon screen. I try logging on several more times and I get the same result. So as it is in this blue HP screen with the options I see this option called "System Recovery (F10)". I press f10, my computer does some loading stuff and then it goes downhill. I've done some research now on system recovery and how i think i'm in deep trouble. When I get to the logon screen, all of the old users are gone, there is a new one called HP_Owner. I log onto that, for some reason my desktop icons and shortcuts come back (I'm assuming because I was on the computer when it got jacked?) but I am still missing all of the other users and such. I found all of my files and the other users files in the documents and settings so it would be really simple to just make new users with the same names as the old ones and then just move the files to their respective "My Documents". Only problem is I also lost almost all of my applications. I now have no Microsoft Word, Excel, Powerpoint, no Windows Media Player, no Turbo Tax, none of the applications that I installled on the computer myself. I tried doing a system restore but I believe the system recovery wiped out all of the data points prior to that date. I also tried the "go back to previous working configuration" (i forget what it exactly was) option and it didn't change anything. This wouldn't be such a bad situation if i had all of the cd keys to these programs, I could just spend a couple hours re-installing all of them. But of course I'm unorganized and I would be hard-pressed to find all of the cd keys. I am running out of options other than just taking the computer in to get fixed or buying some program that might not work. Please help.
