ok im not sure how it happend, but here's the story:
i installed system mechanic 5.5a on my computer and ran the junk file remover thing. since it was taking so long finish, i hit Cancel and deleted the files it had found (over 400). then i just restarted my computer and the problems began.
the first thing i notice is the the Welcome Screen on windows has been replaced by the one in windows 2000, where you enter your username and password. second, after i log into my account, the task bar is all messed up, its being blocked by a white line of some sort (even the Start button is gone). now i start freaking out (i ran many virus and spyware scans but nothing). then i click on the system mechanic icon and then it says something about a corrupt registry. ok so now im really scared because i go on the internet and download some registry cleaners but when i click on them nothing happens! Windows wont let me start up programs taht i download!!! so then i try Scandisk and nothing...i cant even run Windows Update...all i can do is conneect to the internet
i ran sfc in the command prompt but nothign happens. it just scans all the way through and closes
now im REALLY scared i don't know what to do. i dont want to reinstall windows because my important software is on the computer...CAN SOMEONE HELP ME PLEASE???
