Last Thursday, the computer would not get past the Windows loading screen, the blue bar under "Windows" scrolls across several times, then it freezes. I did some searching on the forums here and found some possible solutions, which I tried. I ran a virus scan and found a couple of viruses in the Java folder, I deleted them from the computer but that didn't solve the problem. I ran Hijack This and it was clean. I also looked at Event Viewer and it had several red X's, most of them being in True Vector Service, Application Hang and Application Error. Sunday I installed an additional fan because I could hear the ones in there kicking up into a higher speed when I was running a virus scan; the scan didn't finish before the computer shut itself down. Last night I used the Recovery Disk and ran chkdsk /r. It went through 75% of the C drive, then it said "there seems to be an unrecoverable error." I would appreciate any direction as to what the problem might be. I don't want to reformat the hard drive if I don't have to; I was not able to back up all my files prior to not being able to access the computer.
