My PC kept flashing a blue screen and rebooting immediately after the Windows XP loading screen finished loading. I used the XP CD to run a repair install and ran CHKDSK and it said "One or more errors were found on your HDD" and thats it. After that, windows boots but before the standard quick loading screen, a plain black screen with a white dashed bar on the bottom loads for about 6 minutes, very slowly. What is going on and how do I get rid of it?
