ok sounds like you may have multiple problems, a corruption on the operating system could be one of them and it could be caused by bad sectors on the hard drive - reinstalling doesn't fix this.

you say its so old, how old? comet only have to replace in 30 days otherwise it takes on the manufacturers warranty.

If you want to I'll look at it but you would need to send it to me. I won't charge for my time, you just pay the carraige.
