I have a feeling that you may have cleaned too much! Did you just clean temp files, cookies and such, or did you have it also remove programs? Maybe you removed a startup program under "Tools" that you needed to keep in the startup sequence. Somebody more tech savvy would have to go through the process of helping you decipher what is in the DOS listings you mention, but I think that once you're able to get that analyzed, someone can get you up and running. At this point, it doesn't sound like you can access the place to reinstall Windows, but I hope you don't have to totally reformat your drive! Hope you'd backed up all your data.
