Have you connected the 4-pin ATX+12 power connector? It's located in the corner by the backplate.


I had the same problem, and found this connector when removing the card for returning it. After plugging it in, it started working.

Remove the processor and ram from the mother board. now connect the smps to the motherboard and on the motherboard. if the problem persists again then u have the problem with the motherboard. if the board gets on then insert the cpu and on the board if this dosent work then their is problem with the cpu. this applies to all the motherboards

I have asus m2n 68 se2 motherboard and amd processor.when i press the power button ,the cpu fan just run then off. .cmos cleared

Before anything you should suspect the power supply. It may be able to start the board for a second, but doesn't have the oomph to keep it running.

In my experience, there are some fans that are loud. It could be bad bushings or possibly a fan that is out of balance. The Cool and Quiet utility will not solve that problem.
Are you sure it's the CPU fan?
If the computer (or it's parts) are less than a year old, they should be under warranty.
If it's the case fan, I'd replace it with either a new single-speed fan or one that has a variable speed adjustment.

Motherboard problem

Chances are the CPU fan may be running too slow, dust & dirt build up under & over the fan blades can be a big factor. CPU fan could just be going. Are you over clocking the system. (IF so buy a better heatsink & fan for over clocking the system).
To check if CPU is getting too hot. Enter the bios & go to the title, "Power" page 2-28. Open Hardware monitor & check the CPU temp & mother board temp. (Make sure the case is closed in normal running conditions).

Asus motherboard M2N-E will not power up

It could be a memory card too. I would start by pulling the memory cards and see what happens.

Is there a connection on the motherboard for your hard drive?

Still same problem. Computor wont come on. Motherboard green lite is on.

would need to get a 4 digit bios post card

like this one on ebay

remove the front panel connectors from the motherboard and use a screwdriver to start up the pc. Thats incase the power button is faulty / stuck somehow.

Can't say which is faulty or what is wrong without haveing a look at it myself..

basicly if you remove everything else but psu, motherboard, vga, cpu, memory. so you have the basics to start up. btw try removeing all the ram, you should hear beeps do you hear any beeps?

So it shutsdown right after power on? Might be the psu, I can't say for sure.

Serious problems with an Asus M2N E SLI motherboard.

I understand how this must be driving you nuts. What I am going to suggest might sound stupid but I have to ask. After your assembly was finished (1st time around) did you check the 4-pin ATX + 12volt connector was correctly & fully inserted into the board? Pg. 2-28 section 6. in your manual? Did you add thermal grease to the CPU. A bad pin on the CPU will give you this symptom. I completly understand if you do not agree with this next part but it is extreamly important you go with it. Take the static bag your board was wrapped in & lay it on a table. Place a piece of foam on the static wrap & place your motherboard on the foam. You can use books instead. Connect your PSU, CPU heatsink & fan, Hd & video card & 1dimm to motherboard. Connect mouse, keyboard & monitor.
Check that PSU is set for 115v (small red slide switch near the off/on toggle switch). Plug in the PSU to outlet.
If the green led on board lights up you have power to board. This is known as a standby led. If it's not on, flip the toggle switch on the PSU to on.
Use a pen to short the power switch. This will turn on the board, no different than you pressing the power button on your case. Goto pg. 2-30 in your manual. Find PWRSW two pins. If the system starts up than somewhere durring install the board was shorted to the case.
