I was using my computer the other day and it froze up so I tried to reset it but it wouldn't so I unplugged it and it will not power back on now at all. I checked my surge protector I even plugged it straight into the wall and still nothing. The green light on the back of the power supply was blinking so I pulled the power supply out and tried another one fromm a different computer but still no go. When I unhook the supply from my board the light will go to a solid green and when I start to plug it back into the board the fans will kick on and off but when I plug it all the way in nothing works and the light goes back to blinking. Is my mother board more than likely shot? I am going to try the HP troubleshooting on the power supply but I don't see that helping. Any advice would be appreciated.

This is a desktop by the way. Also, there is a battery on the board would that have anything to do with it if it went bad?

I have everything unplugged from the computer and power supply all I have hooked up is the power to the board.

Barebones. Take out everything but the essentials
One RAM chip
One Hard Drive
Keyboard
NO USB DEVICES
See if it still does it
Plug back in one-by-one to see what is bad
Same thing happened to me with my HP and it was the board, but you might get lucky.

It sounds like you have an electrical short between the connection of your power supply to you motherboard. Is the same exact symptoms occuring when you tried the other power supply?
I would take the power supply from the broken computer and install it into the known good computer. If this works this takes the PSU out of the equation.
I would also go to the bad computer and disconnect every connection, pull out all the add-in cards etc. Now reinstall everything and ensure all your connections are good. Smell the Motherboard, do you smell a burnt smell? Double check everything and try again, hopefully this will work for you - I'd even pull out the processor and the CMOS battery and reinstall them. Make sure no metal contacts are hitting the motherboard. Like i said it must likely will be a short in a wire, connection to MB or internal short in the MB itself. However, its best to try all the easiest and cheapest checks first before replacing components

This could be the power connector on the motherboard has a broken circuit on it. The thing wasn't designed to be plugged in and out a lot of times. If the plug on the mobo moves at all, it has been broken from rocking the plug back and forth to remove it from the mobo. Might be repairable at a local computer shop. Probably created a short on the mobo. Make sure that you use a power supply from HP as a replacement, others won't work. The battery is for the CMOS, don't remove it.

I know this sounds stupid but make sure that the voltage on the power supply is right. If it says 220 flip it back and try again. There is also a button back there, flip it and try to fire it up again.
Otherwise, if none of the answers above work, its definitely your motheboard.
Good luck!

It sounds like it could be your motherboard. Try and get hold of another to test it.

Time to take it into a repair shop.
