Why Won't My Computer Boot Up?

Episode 1767
Larry fromLarry is having an issue where the computer he built is suddenly freezing up and not letting it reboot. So he's gotten into the habit of using a bootable backup. But now he can't get the computer to boot back up. Leo says that most problems like this can be solved by just reinstalling Windows from scratch and starting over. But if it's freezing during the boot, then it could be a host of things, including cabling. One key is to wait for the "beeps," or Power On Self Test (POST). If it beeps, that indicates an issue. Also, pull out your dedicated video card and try rebooting.
