August 30, 200916 yr Short version, friend's computer, a HP desktop about 6 or 7 years old. Started having problems on start up. I do not have a meter handy but it seemed to be the power supply The power supply shut down while I was troubleshooting. POS HP case used a 150 Watt PS, can't find a replacement locally that will fit in the space allotted. Picked up a new case, started moving components. Installed mobo, HD. Started up and zero activity. PS on new case does not start. Outlet and cords are good. Started hooking up SW from mobo to front panel, old case does not use reset. Couple questions. Shouldn't the power supply fire up even without any load from the mobo, etc? Or are the switches on the case front necessary? Unlike the old case and PS, their is a switch on the power supply itself. Thoughts? I'm starting to think I have a case with a DOA power supply, but that seems really unlikely.
August 31, 200916 yr My first guess is that there's a problem with the power supply, the power button isn't connected from the case to the motherboard correctly, or there's a short somewhere. Do you have another computer to test the power supply with?
