My computer lately routinely shuts down about 10 minutes after I log in. I have to wait a few minutes before I can start up again. Usually it automatically starts a disk check, and I get a message like this: The size of the \Documents and Settings\acer\Local Settings\Temp\~DF6F93.tmp [or ~DFECFD.tmp, or ~DFA86B.tmp]entry is not valid. I have an Acer Aspire 5100 computer and use Windows XP.
