It sounds to me like a virus. Boot up from a recover cd or windows cd and reinstall freashly.

If you don't have a recovery cd, contact Toshiba for one. They go around for $40 to $50. If you can't get one, buy Windows Vista and boot up from that and reinstall.

on a friend's Windows 98 SE or Windows ME computer, create a floppy "Startup disk". Insert in your pc floppy drive and turn on. If floppy drive was not accessed, then get to BIOS and ensure "Boot from floppy drive" is set prior to "boot from hard drive". Once at first screen, select "Boot with CD-ROM driver". Insert CD-ROM and initiate entire re-install of Windows. Windows may do some self-restarting. At first restart do this: get to BIOS and ensure "Boot from hard drive" is set prior to "boot from floppy drive".
