did u put the RAM properly?

no HP PC stated just a MOBO. must we guess?
no the power button is just 2 wires, a digital line and ground
it must be plugged in to the correct MOBO jack.
in fact i can turn it on with a simple jumper wire, there.
i guess you found the board, in garage sale, just tossed in a box?
if the local vga jack and added in VGA card both fail then its a mobo issue.

im googling for you.
lets see what POPS
Compaq Brio ATX PGA370 New D7580-60003 *
This motherboard is only compatible with Celeron 400 CPUs
With integrated SiS Super AGP graphics controller?
takes 1 good RAM stick.
if the fan fails to stay on, that means the PSU sees errors.
mostly sees shorts on MOBO(remove things to find it)
that one old mobo is rare, now.
is the coin cell at 3vdc, or below 2.9v, if yes, needs new one.
HP has zero data (information) on this old mobo or the COMPAQ BRIO anything.

The spray on the MB should not be a problem - unless it was plugged in when you did it. Yes, you should be able to put in a new Dell motherboard. As long as the processor is of the same class, the Dell license should work fine. However, you may need to download new drivers for the machine to run.

If you really want to check the power supply, I would suggest you buy a tester. They are fairly cheap: $10-50. You want to be sure that your board is getting the right power at the right places. 12 V to the fan is fine. However, 3.3 v or 1.5 v?

It sounds like you have done a fairly good test of the motherboard. I've definitely seen bad Dell motherboards with the light on with/without a bad power supply.

If you have another case (an ATX), I would buy an Asus or other motherboard and put your equipment in it. The cost of a Dell motherboard is excessive. Of course, you will have license problems with XP.

You motherboard has onboard video. It's possible it needs to be disabled and the option changed to use the pci or pci-express slot for the Ati card you installed. Since you have no post error beeps this is the best place to start. Also I had built a system not to long ago and had a similar problem. Resetting the cmos on the motherboard (usually a pin combo) solved the issue.

Start by hooking up your vga cable to the onboard video.

Hope this helps.

When you say "does not start", does that mean none of the fans spin, the hard drive does not power up, CD drive door won't open, no lights light up on the motherboard?

If any of these are happening, let me know. I would start by unplugging all the things you added except the CPU fan first and see if it now powers up.

If it is indeed powering up, but there is no display, perhaps the video card is not properly seated (assuming video is not integrated). Also, you did not mention if you had plugged in keyboard, mouse or any other peripherals.

Start with as little as possible and when you get power, add one item and check, then add another and check.

Let me know if you need more help.

Try taking out the mobo and ps out of its casing, lay it on a table, hook things together and power it up. I had some problems before caused by mounting studs or try insulating all stubs from the mobo. hope this will help.

it could be your power switch, veriy that it isnt the power supply by

1.) un-plug it from the main board
2.) look at the main board connector(one coming of the power supply)
3.) you should see green wire and next to it a black one
4.) using a paper clip bridge the too wires
5.) if it works proceed to net step if not get a new power supply

to check case switch and board switch

1.) plug in power supply to main board
2.) look at the pins where the power button connects to
3.) using a metal object (blade screw driver) bridge the pins

if the board should start up>
then its your power button on the case that is bad, you can try to repair it, chage it or buy a new case,

if it doesnt work.
1.) ensure that jcms(jumper to flash the bios) is set correctly
2.) unjack each drive one at a time to see if any is causing stalling
3.) get a new main board

try the board with out memory and hard drive.
Do fans run?
Anything?

Its the Mother Board..I had the same problem and had to have a new MB put in
