I just recently got a semi-newish computer fixed (had a power source problem) to use at college that had previously been a family computer. My brother had downloaded a lot of spyware and adware, so I used a program to remove it. Then I decided to fix a message I had been getting on startup about my cdr driver not working and the "device being disabled." I deleted a few drivers that were "unsigned" and also accidently uninstalled and then reinstalled my cdr drive. Since doing this, Windows XP will not load. I get a message while booting that says "We apologize for the inconvenience, but Windows did not start successfully. A recent harware or software change might have caused this." My options are:

Start in safe mode.
Safe mode with networking.
Safe mode with command prompt.
Last known good configuration setting (most recent setting that worked). Start Windows normally.

None of those work, however; each one just reboots to the same error message. I think "Last known good configuration setting" would work if I hadn't disabled Save State, but I did that when I was removing the spyware.

As you can probably tell, I'm mildly computer illiterate -- if I knew more, I probably would not have raped my computer with such savage disrespect. I don't know the make or model of my computer or the patches it has. If anyone could help me make it turn back on, though, I would be forever indebted to that person, because my classes started yesterday, and I really need it to work. Does anyone know what to do?
