Many apologies if, somewhere in here, this has already been addressed. I have no clue where I would begin searching. Anyway, if someone can help it would be greatly appreciated. What has happened is this ... we bought a used tower and kind of got hosed on it. For one thing, the ad said 1G ram and it only has 512 mb ram. Bad news right off the bat, I know. Secondly, the system boots up as Win 7 start up, etc. then major problems start happening (black screen and all). When I went to Computer and checked the hard drive listed, this is where it gets weird to me. The hard drive listed says it is WinXp_pro on the hard drive. What?? I am assuming that the person who had this before tried to do an install over XP and it didn't work and they flogged this tower to the first unsuspecting sucker (which would be me). Anyway, just wanted to ask if my assumption is correct? There doesn't appear to be a windows.old folder on the system so looks like reverting back isn't an option. Any thoughts on what kind of a mess we have here? Thanks!
