Hello, my previous pc was WinMe and I had a similar problem, but after I went to microsoft winme update and had all the patches installed the problem disapeared, also have you checked how much space you have allocated for System Restore? it might not have enough, I would also check the system tab on control pannel and make sure system Restore is enabled, other than these it could be spyware, a trojan or other malicious software trying to stop you from restoring your pc to a previous time. good luck , mrobto |
