Hey gang, I have an unusual situation with a machine that I build for a friend of mine. It is a Duron box, everything was installed new, including the case. Here is the problem. When he turns the computer on, the monitor light stays yellow and doesn't come on. If you turn the monitor off and on, it sometimes comes on. But even stranger is, if you turn the computer off from the switch on the POWER SUPPPLY and not the front of the case, everything works ok ?? Any ideas ? Thanks a mil !
