About a week ago I started having some problems. I decided to first unplug all the additional items (usb printer, etc.) and just left the monitor, keyboard and mouse connected. But then when I went to plug the unit back into the electrical outlet the little green lite on the back of the tower did not lite and I had not power to the pc. I went to the HP website and followed the trouble shooting steps ---
which is why I am now thinking that it my be the power supply unit. I was doing some research and instead of just getting a new psu some sites state to test the power supply unit first. Some of the sites suggest testing the power supply unit manually with a multimeter or with a power supply tester.
I do not have a power supply tester so I would have to go out and get one of those first. I do have access to a Simpson 260 VOM. The Simpson 260 VOM (volt-ohm-milliammeters) looks different from the multimeters I have seen online from this one. Primarily because this Simpson unit is much much larger; in a hard black case and is not digital.
Can I use this Simpson VOM to test the power supply? If so is there anything specific I need to know or does anyone know where I can get information on exactly how to do this (don't want to make things any worse than they already are but the closest place to take it in for service is about 40 miles away and I can't easily take the tower in since I am disabled).
I will look at the information for the paperclip trick - I did just look over it briefly but I do not have a power switch on my psu - I just plug the power cord into the unit and into an electrical outlet and turn the pc on with the little button on the front of the unit.
