PC Not Powering on... Why not?

Also, try powering up with nothing plugged in, then add one component at a time. Even the ram, if you get some beeps about no ram, that's a good start.

check for the yellow/green lights on the back of certain dells. odds are power supply or mobo, they both suck on Dells. Well, pretty much everything on Dells suck.

Follow the black cord from the PSU to the wall socket.  Is it plugged in?

You be surprised how many of those calls I took at Tech support.  :lol

Depending on the model, alot of them have little boards for the button/error lights, which connect to the motherboard via a ribbon. annoying. However, if this is not the case on this model, he means there should be a set of wires that goes to a 2 pin switch on the mobo, and you would just kind of pock them with either a jumper or a screwdriver.

What model is it? GX240 ? 270/280?
I would bet it's the power supply, especially if it is a 620.

I'll check tonight.  I've poked around inside but haven't gone too deeply yet.  The wiring behind the power button is difficult to get to without removing plastics and components.  I'll try to trace back what/where I can.

I currently have everything (monitor, speakers, keyboard, etc.) disconnected, it's just the PC and it's internal components at the moment.

I'll unplug some internals and see what happens.

No beeps, no buzzes, no crunching of HD.

Ha,
Understood, but that's why I made sure to mention that the MB was getting power of some sort as evidenced by the little green light. If I remove the plug the light stays on for 5-6 seconds and then goes out.

Not a complete spaz!!  ;D

Thanks for help so far.

OK I reread your original post.

Check power coupling on the mainboard.  Take the MB power connector off, switch on the PSU with the drives unplugged.

Reseat power coupling on board and slowly attach each drive (if you have more than 1) to the PSU.

I had this problem on a Gateway, drove me nuts until I did that and it came back.

Drain BIOS and then retest if above didn't work.

Again outlet check voltage with a multimeter, maybe you are not getting enough juice, try other outlets in the dwelling.

Reseat the I/O cards.  I had a problem with a faulty video card that did something similar.  One day it was working, then after a server move it did not.

Lastly check the mainboard for any damage or vibration that might have goofed a component or is something on the traces.

Other than that - bin it.  :cheers:
