The computer shuts down and reboots on its own when I try accessing the floppy drive. It will sometimes open the folder on the floppy but when I try to open a file in it...... well it crashes. The floppy drive was on the same power cord as the HD so I moved it to its own and it still does the same thing. Does this sound like a power supply problem or a floppy problem? It does it with win98 and XP which I just installed.
