I have a Dell laptop that had no AV software installed. I could see right away that it was infected with various types of viruses/spyware and used AVG and AdAware in safe mode to remove them. After the scans I am able to boot to normal and safe mode but Windows does not load after login. The screen just remains blank - in safe mode it's just a black screen XP version at the top, and in normal mode, it just shows a blank screen with the desktop background.
All I seem to be able to do is ALT+CRTL+DEL to shutdown, restart or logoff.
XP Repair Install doesn't seem to be an option. I am able to get into the recovery console though and have already tried chkdsk.
Is there anything else I can try before a clean re-install ?
