How will I run hard drive corruption to scan on XP?
When I did update to my computer such as anti-virus updates and others, the electric power suddenly shut off. After that, the electric power comes back and then I turned my computer immediately. But when my computer opens it just display a blue screen and it says that the hard drive was corrupted and I should scan it.
Or disable my antivirus protection of my computer. I did the instruction that the computer told me to do but nothing happens. How will it help the computer? And how will I do that?
