I am working on a Dell E150 that won't boot up from the hard drive. The computer also won't boot up from any CD I place in the the drive. I've tried with the Dell Windows CD and it get's as far as the "Windows is starting" message. I've tried the Ultimate Boot CD, Ubuntu CD, and Knoppix CD. I can't boot into any of them. These CDs work in other computers just fine.
I've tried replacing the cd-rom drive, the power supply, video card, and removed all other non-essential parts connected to the motherboard (like the USB connectors and a modem card). It's not a hard drive problem because I've put in a hard drive that I know works and I still get nothing. I've reset the BIOS settings as well as well as played around with disabling onboard functions of the motherboard. I've replaced the RAM with sticks I know are good.
At this point I am suspecting a faulty motherboard or CPU. Any suggestions?
