I'm hoping ya'll can help me troubleshoot a friend's computer. Recently his computer began failing to boot up. when power is on, the fans would start, but it would not continue to boot up.
At first I thought it would be the PSU, because the same thing happened to mine, and a new PSU did the trick. However for his, the new PSU did not resolve the boot up issue.
What would be your next steps for troubleshooting where the failure is? The computer is a Dell Dimension 2400. I could take the hard drive out and put it into my machine to make sure it works, but I don't know how to test the motherboard (however when power is on, the green LED on the board right next to the power connection is on).
I guess I could buy a new motherboard/RAM for it, but trying to get this fixed for as absolutely cheap as possible.
