Hey I have a 1.6 Ghz AMD Duron with 512 ram that I built yesterday. When I booted it up and installed everything, the computer worked fine. However when I shut down the computer and try to reboot, nothing happens. The power is there, the cd drives are blinking and I dun even get to the bios. However, when I unplug the cd drives, then I get to the boot screen. THe keyboard will work only while the ram is counting. Afterwards, nothing works. Anyone can help me? I tried clearing the CMOS already and no go.
