Re: Power Supply is Okay - Morherboard ???

Nothing you have said confirms your title that the power supply is ok.

Anything in the entire computer can cause this, even a disk drive.

The power supply is the first thing I check, as much because it's easy as because it's a likely cause. The next most likely thing is the motherboard. After that, memory, CPU and then expansion cards and drives.

There is no easy way to diagnose this type of situation. Ultimately, it's done by some form/combination of device substitution(s) and testing where that is possible (really just the power supply).

First off, I apologize for this not being a Dell problem but I am working on a HP Pavilion a532x for my daughter's friend and am stumped.

When the power button is pressed, the CPU, case and PSU fans come on full speed but nothing else happens. The PSU tests okay and the HD spins up. The capacitors look to be in good order with none having visual signs of swelling or rupture. All the cards have been pulled with the same result.

I don't have any experience with testing motherboards and my feeling is that this one is cooked. Is there something that can be done to verify that this is so using only simple tools and a multitester? I'm trying not to spend $150 on a new motherboard to find out this one is okay.

I have to say HP Web support is better than it was the last time I used it years ago but I can't find a newsgroup or forum like this to post questions.
