i go to log on screen and put in the password and it takes 2 min to get to the desktop and nothing loads. all of the processes are running in the background because i got task manager to run once but i cant run it any more. how do i start windows in DOS without logging on. I downloaded some new stuff and it is probably a virus, i can delete it, but i cant get to it. the computer is fast but now it is running very slow and the mouse lags
 
Hi Trevor,

If you know exactly what the name of the file is that is giving you
trouble, you can boot with the Windows XP CD, and go to the Recovery
Console typing R. Once there, select the Windows installation you want
to repair (usually 1) and enter the password you used during
installation (there might have been no password, if that is the case,
just press enter).

Once you have the prompt, go to the directory where the offending file
is and delete it.

If the directory is not in Windows, you have to type set AllowAllPaths
= TRUE in order to go to other directories.

More info about the recovery console here:

Good luck, hope this helps.

I ran into the same problem recently.....I could hardly run anything because the CPU was pegged continually at 100%. I did an 'F8' at startup (right after the display of the XP Home Edition banner page, and before the welcone page appears....picked 'safe mode' for startup....used the run command and ran msconfig. When I deselected (click on the box in front of the application) realsched. the cpu returned to normal and the lllllooooonnnngggg periods between the ability able to execute anything went away. I still have the 2 minutes from startup to full desktop functionality problem (which doesn't appear on my other XP machine), but hopefully I'll be able to figure that one out also. I've been working on this one intermittently for the last couple of days
The msconfig is a pretty good way to do some preliminary diagnostic work and could help point to what ails.
