Initially, my cpu fan and power supply would only come on for a fraction of a second; then I noticed that I had some bad capacitors on the board; I replaced the capacitors and the power supply and cpu fan come on but there is still no output to the monitor. One other thing that seems odd is that I could start the computer with no problems by pressing the power button but I cannot turn it off. The motherboard is an AMD board that is apprx 2 years old that had a 1600+ AMD athlon chip on it. I think the motherboard is gone and needs replaced. FYI, the PSU has been replaced and I tried another AMD athlon chip on it; still no go. Any suggestions that I could try before throwing it away???
