My rig is a Pentium i7 machine, running Win 7 Professional. For the last 3 months or so, I've been advised by my ISP Comcast that I may have a bot.
I've run several scans using Malwarebytes Antimalware, ESET, MS Security Essentials, without any detection of malware. However the machine started to crash more and more often, especially while I play an online game, World of Warcraft. I did several chdsk to find out and repair any disk error but that didn't seem to help either. Finally it crashed to blue screen a couple days ago, and has since been unable to boot, giving me 2 options each time: Repair computer or Boot normally. I've tried doing the Repair computer route several times, and it's told me it's repaired a corrupted file system, but when I try restarting, it would fail to boot again normally. I've gone back to the original Windows installation disk, with similar results. Essentially I'm stuck in an endless loop of "Repair my computer", without any apparent hope of breaking out of this.
I would be very thankful if you can help me with this problem. I've looked through the website here but have not found any specific thread addressing this problem yet. If there is such.
Thank you very much for your help!
