There's a problem with 2 of these which have floppy drives that are unreadable. They don't light up or post when computer's booting up. I tried leaving a floppy in there while booting, nothing happened. I installed a new floppy, and even used another floppy cable, nothing happened. I tried uninstalling the floppy and floppy controller drivers a few times and rebooting. The only conclusion I've come to is that there's something wrong with the onbord floppy controller. Has anyone else run into the same or similar problem? Any suggestions whatsoever will help me.
