Specs: Soyo computer, Via bios, Athlon 2.3g, 640meg Ram. All electronics on motherboard.
Symptom: Power up, hard drive runs. No display. No beeps.
Mfr suggestion: Disconnect everything; cards, ram boards... everything but the speakers and reboot. They wanted to know what I hear when I do that. I don't hear anything. They say this indicates either a microproccor error or a bios failure.
If it is the microprocessor or the bios chip I will replace the motherboard and be done with it. My question is, could it be the power supply? I can easily test +5V and +12v, and they are present. Is there a way to test the other voltages coming from the power supply? I tried unplugging the cable to the motherboard, but there must be a connector-interlock - I didn't even get the +5V.
If you were me and were ready to shotgun this thing, how would you proceed? Keep in mind that it is my wife's computer and it has been down for over a week. My main priority is to get it up and running as fast as possible. I hate to spend the money for a new motherboard and CPU and then find out that it was the PS all along.
Choices have consequences.
