My computer will not boot up
I have been having a very strange problem with my computer. It all started a few months ago when I lost both my hard drive and monitor within a few days of each other. Since that time I have gotten another computer, but I am trying to get this one running again. The problem is that no matter what I do, it will not display anything on the monitor when I turn the power on. I have replaced everything I can think of. I have used a different monitor, a new motherboard, a new CPU, and I have recently tried swapping cases. The only thing I have not done is use RAM other than what was in the system. That is because I had three different chips. Back to the display...when I turn the power on, the light on the monitor just changes to amber, and never goes green again. Everything spins up...the hard drive, the case fan, and the heatsink fan. If anyone can think of anything that I could do to fix the problem, I would love to hear it.
