BAD PC problem HELP

I think they usually suggest a registry backup first. Did you perhaps do one?I think you should be able to, (but I'm guessing) run programs that aren't "installed". That is just run an exe since they shouldn't have any reg entries. I don't know what ones would help. I'm afraid this isn't very helpful. But maybe it will attract the attention of someone who knows something.To save others this problem, what was the name of the cleaner?

I think, if nothing else, your computer is just too slow and with two little memory for XP.

Mike! I am astonished that XP runs at all on that machine.I hope you can find some money to get something better. But don't try to upgrade what you have. Start with a whole new box (well you might save the case).
