I had an old Gateway PC (model e6300) sitting around and I decided to upgrade the memory and video card. I maxed out the RAM @ 4gb; worked fine. I had a PCI-E vid card, installed it and everything worked fine. I also had another vid card that I wanted to test out (which I know was good) and everything worked fine. The drivers were out of date, so I updated them and then my computer would boot up and when windows should start to load, the video would go out (obviously a driver problem). Now, I turn it on, the fans turn on but the drives do not boot, nothing happens. It doesn't even boot to BIOS, I took out all of the RAM and vid card and powered on to check for the beeps (easy way to check a mobo's integrity, no?) and nothing. I'm pretty sure this means my mobo is no mo'. Now, I know that my cd drive was on it's way out when I started all of this. If my cd drive kicked, would this prevent my system from booting up? I believe that my cd drive was first in the boot order, so if it was dead, could this be the culprit?
