I've been looking all over the internet for a power switch for this mother board. I have many spare PC's lying in my attic and not one power switch off of any of them will fit this. Anyone know a place to where I can find a power switch?
I would like to get this PC running ASAP. Thx in advance!

Re: Power Switch for this PC?
I've read your question & am still confused about which switch you need. I'm guessing that it's the power switch on your case that is broke? If so you can go to just about any auto parts store & buy a push-button two wire off/on switch. Even in a Low's store. It may or may not fit just perfactly on your case but it's better then turning the power off with a pen directly off the motherboard. Been down the road your on. It's either this or buy another case. You will not find your case a new switch. You can use your case's wiring connector to plug into the board listed on pg. 1-18 in your manual. It's two pins. You can splice the two pin connector from your case to a new switch's wires. As far as connectors go. You can buy a small pack of single connectors for a computer from radio shack to connect to the boards (power) ATX power switch. All the parts shouldn't cost you more than $10.00. Cheeper than a new case!

Bad power supply first, or just the switch. The mother board will keep it from posting, but lights should come on. a bad power supply or switch it will be dead like fred. If your handy there are many tutorials on diagnosing a power supply on the internet. Usually when it is the mother board there will be a few beeps or flashing lights then a shut down, or frozen pc on boot then death. But all these symptoms can come from a dead or dying power supply. http://www.overclock.net/t/96712/how-to-jump-start-a-power-supply-psu-test-a-power-supply-and-components Do this at own risk..
there is a 9 pin color black at lower right side of your board if your infront of it, in usual position. firs t(2) two in upper right is for the power switch, and the two pin behind it is for the reset switch. the two pin beside of power switch at left is for power LED/Light, behind that is for HDD LED. spare the last pin left at lower right.
Check ALL your USB ports..
If any of the USB ports have shorted contacts or if the 5v rails are shorted to ground, the power supply WILL NOT switch on.. Also, if any of the items connected to the board have a supply rail grounded, again the board will not allow boot up. Unplug everything from the board and the drive power connectors too, except the power connector to the board and the front panel switches and try to switch on, if it still will not boot, check and recheck the USB ports and all power connectors, if it does, switch off and plug another item in, then switch on again. When you get to the item which prevents the board from switching on, thats where your problem lies. Dont forget, plug things back in one at a time, including the power plugs to the drives and try and power up between each item, and dont forget to power down after each item has been checked..
Could be either one, or it could be the toggle switch.
Start with the easiest first to check. Unplug the power toggle switch from the mainboard and take a screwdriver or something and short out those two pins to see if it starts the pc. if it does, then your pc case switch is just bad.
If that's not the problem, check the power supply next.
Jumper the ATX 20 pin power cable's green wire to any black, just to make sure the power supply is working. The fans in the power supply will turn on along with anything else hooked up.
To jumper the power supply use a section of wire or a bread twisty (with the insulation removed from the ends) and just connect the green wire to any black wire on the 20 / 24 pin power connector. Make sure that the power switch on the back of the power supply is switched on.
If neither of those seem to be the problem, then most likely it is the motherboard or the processor.
