Hey Guys you helped me when I had a problem 
But now sister has downloaded a beauty of a virus (I think) 
Windows XP Home starts up with the welcome and her name click to log in an it says loading your personal settings, then it shows the desktop with no icons for a bit then shuts the desktop and her name comes back on the screen and then logs her out.. 
It won't let me start it in safe mode, it will let you select safe mode then it just takes you to log in, the same for last known good settings and I tried to boot to the windows disk after going in to the bios to change to boot to cd rom 1st and it gives you the option to install windows or Repair so R it is and it asks which version of windows to repair and comes up with 1:F:\WINDOWS_ makes no change what you enter..
HELP.. thanks Mark
