You can try booting into the repair console on the CD and run chkdsk on the drive.

You will notice it has a problem in the beginning clusters

The system may have a virus run the virus scan and other malware utilities to see if you can troubleshoot error.

When booting system press F8 and use safe mode to run scndisk on the system,you should be able to run your anti-virus from here also

Have seen similar behavior on 2 PCs. Both were heavily infested with adware and spyware and, I think, several viruses probably downloader trojans.

If winlogon is corrupt, you cannot logon in safe mode either.

Are you getting a WinXP background screen with no icons or taskbar? If so, press Ctrl-Alt-Del to bring up task manager and run explorer through task manager. Post results.

Do the following disconnected from Internet.

If you have WinXP install CD, boot from it and run the install. When XP installation screen appears (after several minutes) see if you have option to do a REPAIR INSTALLATION. (Am not referring to recovery console). If Repair installation is option, do an overwrite install. As soon as possible after installation, boot into safe mode and run msconfig. Choose Selective Startup and uncheck Load Startup Items. Reboot, install a recent version of Ad-Aware or Spybot and remove what malware you can. Run a virus scan.

Reconnect to internet. Install other ad-ware removal program not previously installed. Update definitions and run both.

Keep running adware removal software until you get clean scans in both or they show VY Better Internet or Cool Web Search left. You may need specifig removal tools for these. Search for CWShredder, Cool Web Search removal, and Better Internet to locate removal tool (site changes).

Post back and let us know more. Hope this helps.

I ended up calling Dell Support. They advised the same as you, only it didn't work. The ended up having to send me a Restore CD (not sent with computer originally). The has gotten the computer back to working but in process lost ALL info that was on the computer. Dell support said they have ran across this before and it seems to be a combination of adware/spyware/virus/and another unknown factor. They said the only way to get computer back up and running at the stage this one was in was to restore it to how it was when it was taken out of the box. Thank you for your help though. MsGwen
