About 3 days ago, I was on my computer. I tried to switch out of my login to a different one, and I got the blue screen of death. Since then, every time I have tried to boot it up, it will get all the way into booting up, but right before the login screen would normally come up, CHKDSK begins running. The lines on the Windows XP blue startup screen say ____________________________________________________________________________________________________________________ Checking the file system on c: The file system is NTFS The volumes is dirty CHKDSK is verifying files (stage 1 of 3)... File verification complete. CHKDSK is verifying indexes (stage 2 of 3)... 8 percent completed. ____________________________________________________________________________________________________________________ It will only get to 8 percent before freezing. I'm very worried that this means that my computer has been hit by a virus, or my hard drive is dying. The computer did this a while back, maybe 2 or 3 months ago, but after a few reboots, it was fine. Even if the computer is dead, is there some way to safely extract my files?
