Dell Dimension 5150

So i'm helping to fix a Dell Dimension 5150. It won't boot at all. When plugged in, the green light on the mobo is lit. There's no light on the power button.

Any help?

Edit:Yeah, it's definitely the button. I took off the front panel--which is actually really, really annoying--and the power button isn't making contact with the black button behind it.

Using a screwdriver to press the button, it boots fine. Well, as fine as a 5 year old dell will boot.

Anyone have any experience fixing this type of a problem? It's not under warranty.

From the best I can tell, the power button connects to a clear plastic connector, which connects to a black button. If you bypass the plastic connector, and press the black button, it boots fine.

I had one like that. On the back of the button, the stem, that pushes against the switch, had a small hole
I was able to use a small screw to add length to the stem
Any momentary on/off switch will work

Make sure the front bezel is fully seated
