Dead motherboard? Or wrong testing?

November 3, 2013 at 11:10:29
Specs: Windows 7, Athlon 3.2ghz/4 gigs
My old psu died, then I switched to an Cooler Master GX 550W. I had booted it up with one of my freinds old PSU (400W). But with the new PSU nothing happends, even when I touches the Power switch with an screwdriver. My new PSU works I have testet it with the paperclip trick, and it works! :)
So even with new working psu, and everything plugged in nothing happens. And i also tried clearing CMOS, Connection and connection the battery. I even tried disconnecting all my expansions cards. But still nothing happens, no spinning fans, or vibrating HDD's, absolute nothing happens.

So is my motherboard dead?

My specs:
Cooler Master GX 550W
4gb ddr3 1333mhz
GA-M68MT-D3P motherboard
AMD ATHLON II x2 3.2 ghz

Expansions:
Wifi card
GT630 4 gb ddr3
Audigy 2

The paper click trick doesn't necessarily mean that the PSU is working properly, although it is a good start. It could still be a faulty unit (it can happen with new stuff).

First step is to remove all connections then re-insert them firmly again just to be absolutely sure.

Some PSU voltage measurements might pin-point the trouble.

Always pop back and let us know the outcome - thanks

Try running without the add in graphics card and drives connected. You have on board graphics, use it for testing purposes.

Be sure you connected the auxillary CPU power connector directly to the motherboard.

Reconnect your friend's psu--the one that worked--and see if it still works. If yes, then the motherboard must be good.

I don't know why you'd be clearing CMOS or using a screwdriver to short the power pins. The BIOS has nothing to do with a PSU swap & there no reason to be messing with the plug for power button. If you tried a 400W PSU after your original PSU failed & the system booted, the board is fine, unless you did something to it that you're not telling us? My guess is you overlooked something when connecting the new PSU.

"GT630 4 gb ddr3"

Well it's certainly not the HTPC graphics card that's drawing too much power, lol. If no 6-pin PCIe plug is required, the card draws less than 75W.

I now it may still work, but i am planing upgrading it anyway. I have looked at an 760GA-P43 (FX) motherboard, is that wise. Because of the unlock CPU core function and cheap price, that would give me 2 extra cores for the Phenom II X2 CPU. I do not have an Atlhon but Phenom. Should that work all perfectly together? Someone who haves experince with that? (CPU core funcion, or just the
760GA-P43 (FX) motherboard.)

I have plugged 24 pin to the motherboard, 4 pin to the CPU. There should't be any more connections between PSU and motherboard, to booting the machine up? Should there, i am an noob in pc's i can't see what more to connect between PSU and motherboard

Lot of general stuff here (inc links to videos):

EDIT:
Probably a silly question at this late stage but have you ensured that the PSU is set to the correct power supply voltage for your location?
