So I have a question for anybody that may have the answer.... The other day my son was using the home desk top, nothing special just a Frankensteined IBM compatable running XP.... so anyway, just after he got done downloading something ( I really don't know what) the PC crashed. Upon reboot, it defaulted to the Safe Mode option.... so far so good. I chose to boot in Safe Mode, however, the PC ran through the Motherboard Bios Screen then hung on a black scrieen with a horizontal cursor blinking. There it sat. When I rebooted it again, it gave me an invalid drive error. I rebooted again, and entered the MB bios setup screen.... It was still recognizing the hard drive. Once again, reboot... now it came up with an error something to the effect of "cannot enumerate files on hard disk..." I decided that my son may have down loaded some kind of boot sector virus.... although I am running McAffee AV (with a current update on the virus profiles). I changed the bios to boot from the CD drive and inserted my XP disk.... thinking I may have to try and reinstall windows.... and it booted up just fine, everything appeared normal. Strange thing is that it didn't even give me the option to install or repair windows.... it just booted. I am thinking that since it allowing me to get to all of my documents and things, I will move all of them to an external drive and wipe the drive and reload windows.... or setup and smaller hard drive that I have as the master with the OS on it.... and use the current drive as a slave. Is this how a boot sector virus typically manifests? Does anybody have any suggestions on how to proceed.... any input would be greatly appreciated.
