Question about ASUS M2N-E SLI (M2N-E SLI GREEN) Motherboard

2 Answers

Serious problems with an Asus M2N E SLI motherboard.

Hi,
I tried to build the following system:
AMD Athlon 64 X2 6400+ Black Edition
Asus M2N E SLI
XFX 8500GT 256MB
2 X 1 Gig Kingston PC2 5300
Thermaltake Toughpower 850W
When it is all put together just nothing happens its as if the power button where broken but it isnt because it still switches my old hardware on, a small LED light on the motherboard lights up when i switch the power supply on. I have tried the CPU on another motherboard and the same thing happened (MSI K9MMV). I then tried another CPU a cheap AMD sempron and this didnt work either. I have trioed multiple PSUs and still no change i'm becoming desperate any ideas what it could be? thanx in advance.

    Just tried it without memory and a hard drive still nothing. Nope none of the fans run, as far as i can see it is still off.

  • RyanUk Nov 22, 2007

    yeah its brand new, so is the other motherboard and CPU I tried. From what i can see all the capacitors are fine.

  • RyanUk Nov 22, 2007

    Yep i ahve the 24pin connector and the 4pin 12v connector on there aswell.

  • RyanUk Nov 22, 2007

    Well the motherboard comes with a Q connector to make connecting the power and reset switch easier and i have tried moving them round so i dont think it's them. I did consider that the case may have shorted the motherboard but then i tried it outside the case on an insulator mat and the same thing happened.

  • RyanUk Dec 01, 2007

    I'm not sure to be honest, i sent the motherboard back and they said it was damaged but that doesn't explain why the processor didn't work in the other motherboard i tried. Anyway i have sent the CPU to AMD for testing and a replacement if it is damaged. As soon as i find out i will rate the comment.

    I had this problem with this motherboard. The green "ready" LED would light up, but no fans, no power. I solved it by checking the power polarity required on the 12V plug. Then I checked the power of the power supply plug & found that the polarity was switched. I located a different power supply plug that matched the polarity, plugged it in & now it works.
    I hope this helps.

    Seem to have the same problem, same board Asus M2N SLI. New board, New CPU, New ram dual, New PSU, New case, New video card. No post, board light is green, all fans on (case, cpu, video card) no keyboard light or mouse infrared. Re-set the CMOS, pulled the battery,pulled the cards and ram, pulled the case usb and firewire cables, even ran the board outside the case with only the CPU, vid card and one stick of ram. Still just the fans and green board light, no post, no beeps. A previous response mentioned reversed polarity at the 4 pin CPU connector. I do have voltage at the connector but any info on the + -  configuration of this plug would be appreciated before I send this RMA.

Hello, I have a similar set up and it worked fine, i.e. brand new mobo like yours, 2GB Crucial DDR2, 512MB Xpressvision cheap graphics card, Thermal take armour case w/ 250mm fan, Big Tyhoon Cooler, thermal paste. Didn't plug all fans in, no optical drive, booted fine. Green light on mobo constant green when rear power switch is on and when turned on at front. Later I installed new HDD, formatted and loaded XP Pro no problems. Sorry you've had your problems.

    how about the power and reset switch, they ok?

  • Thomas Christopher
    Thomas Christopher Nov 22, 2007

    when you installed it, there are no shorts where it mounts in the case, are there?

  • Thomas Christopher
    Thomas Christopher Nov 22, 2007

    I am afraid that you may of gotten a bad one then. Take it back and get it replaced.

    You have tried everything possible. It shouldnt be that difficult.

Hi Tomokato,
This maybe nothing but the first thing I checked is the CPU.
Supported CPU list through Asus web site for M2N-SLI
(Click on this link). http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us&model=M2N-SLI
The first supported 64 X2 is;
Athlon 64 X2 3600+ (CU),512K,65W,rev.F2,SocketAM2
Second CPU supported;
Athlon 64 X2 3600+ (DD),1MB,65W,rev.G,SocketAM2

The CPU that you are using is not supported.
Since this is a new CPU, you might be able to exchange it for the Athlon 64 X2 3600+ (CU),512K,65W,rev.F2,SocketAM2.
Link to Asus main web site for M2N-SLI.
http://support.asus.com/download/download.aspx?modelname=M2N-SLI&SLanguage=en-us
Suggest you add the above link to you're favorites.

Even you're memory is not supported. As seen in user manual page. 2-13.

Have more questions, feel free to ask.

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.
