I got home the other day and I had an illegal operation from my firewall. I got out of it and it shut my firewall program down. So normally if I have any kind of illegal operation I restart my comp. and start fresh. Well I did that and during bootup it told me one or more of my sectors on my hard drive may be damaged and it needed to run a thourogh scan disk. I let it do it which took about 4 hours. Nothing was found. Now anytime I boot up I get the same message. I just exit out of it. Do you know what could be causing this. I keep my virus scan updated and I scan my entire system and nothing came up there either. Any ideas.
