What is the most probable things to cause a computer to hang up when it is booting up. From time to time, this computer will get stuck when it reaches the point during boot up, where is says "checking DMI files."
Sometimes all I have to do is reset it and it goes ahead and boots up successfully. Today, when my wife was using the computer, it suddenly reset itself and started trying to reboot. It got hung up in the same old place and nothing I tried would coax it into rebooting. I shut it off and gave it a rest and then tried again later. It still wouldn't boot up until I monkeyed around with a DOS startup floppy. The startup disk didn't really do anything, but after I hit the enter key a couple of times and then reset again, the computer went ahead and booted up successfully.
Any suggestions?
