My unit won't power up - power supply is good and not sure about the on switch any help would be appreciated -- motherboard is in an old HP Pavlion 700 case

Remove the little watch type battery from the mother board check the voltage with a meter should be about 3.5 volts. Then replace the battery on the mother board. This battery holds memory within the Bio chips on the mother board, if there was a problem that it sensed for turn on it will be in the Bio's memory, and maybe not allowing the computer to turn on, by removing the battery for a few minutes, the Bio's forget they had a problem, if you will. and the computer might turn on.
If you have all the voltages to the mother board from the power supply, it should turn on.
unless there is some reset circuit interfearing with it turning on. Or you might have a blown fuse on the mother board, I would check everything I could, and try everything I could, and if you still cannot get it to turn on take it to a computer shop and spend a few bucks for them to fix it.

Will not boot

You can goto BIOS setup be pressing DEL, ESC, or one of the "F" [function} keys just before " memory count " finishes.To see what is turn 'on' or 'off' look through the menus & submenus.look for video [ ON if you have 'on board' video and off if you have a EXTERNAL video card.]
temperaty take EVERYTHING out by unpluging the wires going to computer (mother board) [cd's, h/d, floppy drive, and any other extras] You can keep them 'dangling' from e.i. floppy, cds [rom,ram,dvd etc.] keep the memory, display adapter (if you have a EXTERNAL video card) and boot up the computer.You must see the memory "count up" in DOS (black screen with numbers running on left side of screen) .At first if the machine does not turn on, replace the video card.Then after UNPLUGING a/c power put back ONE piece of equipment at a time (of cause you will replug a/c power)and rebooting.

The power led and reset was both on

We have to open the system unit where the motherboard is located, but first pull off the power of your computer so that there will be no ground.

Removed the cover, before touching any part inside the system unit (motherboard) touch first the casing or chas-is of the system unit to removed the static in our body.

Let us first remove the reset wire usually the color is red and black it has a name reset at the connection pin at the mother board usually found at the bottom of the mother board, or follow the reset botton wire found infront of your system unit.

After you have removed, try to plug the power of your computer and turn it on. We can open our computer if the reset connection is off.

That will be the first step to know the cause of the problem. Try also to clean the motherboard using vacuum cleaner the portable only or clean paint brush, cause some of those problem due to dust.
