Check the hard disk if its properly connected, then remove the cmos battery for 30 minutes then put it back, try to boot to cmos/bios then check if its reading the hard disk.

Check your power supply. Sounds like a bad or insuffecient power supply.

Cant get computer to


Disconnect everything from the motherboard except the power supply, CPU and power switch.

Turn on the computer. You should hear 3 beeps because you removed the memory.

If you don't hear any beeps, check the power supply. Check all the connections. Did you connect the 4 pin power? Did you skimp on it? A common mistake is to get a cheap, high-power supply. Just because the box says it's 1000 WATTs doesn't mean that will carry a steady load.

Still nothing...

It's either a bad motherboard or processor. If you have another processor that is supported on that board and you know it works, try it. If it boots return your CPU for a good one.

Unfortunatly, if it doesn't boot with a known-good processor that just proves the board is bad; it doesn't prove your CPU is good. You may have more issues.

I had an asus P4S800 MX motherboard and power supply and I think I have everything setup the way it is supposed to be. The power light is on the motherboard, the monitor and keyboard are plugged in, and...


hello brother..you must replace your motherboard! the problem with this asus series led consumers to panic. P4s800-mx boards are sensitive on power surges..this boards i think did'nt pass from power test tolerance. they can't withstand abrubt power changes. even the green light onboard indicates power presense and the proccessor's fan is working, believe me.that is already totally dead, even if you try to change the power supply it will not work either unlike asus's early version like p4s533mx, p4b533, p4v533 etc...are more reliable on power changes.this is the downfall of p4s800mx..but if want to still revive it, you must have a good skills on soldering small components..p4s800mx regulators sucks and even you replace it, it will bear the same problem.i only have the chance to post this solution because i noticed that anyone seems dont have a concrete solution regarding this..i already dumped 300 units of this boards. because there is no posibilities to elongate the life of this boards you are very lucky if you still have this boards(just try to use HQ voltage regulator to protect it.) the thing is, the tiny capacitors lied accross the processor at the solder side is always malfunctioning and the power regulators(component side) always changing in value that dont sychronizing to the power needed by the board...please pass my solutions to our members for them to understand. i am a filipino and we have a wide posibilities of solving this problems we love technology and technologies are just made by us we all have the solutions.

thanks brothers.....

Go to the Asus website and download the drivers for this board. It's most likely that it did not come with drivers installed. Hopefully this will fix the problem. Good luck.

Power supply


I think your problem is not with the power supply, its the hdd or memory thats causing the problem. try to check the cables, and re insert the memory then start up your pc again.

No Output to monitor, no beeps, fans all OK


Hi karanda,
The green led on the board shows green letting you know there is power to the borad.
Does your GFX card have dual outputs? Try plugging into the other output.
If your monitor light goes from green to amber than your PCI-E is not putting out signal. Pull & re-seat video card.
Did you check Asus to see if your CPU is supported & check what bios version you may need to run CPU?
Chcek here: Check what your M2M-E supports.
http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us

Your board only supports these two CPU's
Phenom 9500 (HD9500WCJ4BGD),2.2GHz,95W,SocketAM2+,Quad-Core
&
Phenom 9600 (HD9600WCJ4BGD),2.3GHz,95W,SocketAM2+,Quad-Core

You need Bios version 0802 in order to run the above CPU's.

Good Luck & kind regards!

Ensure that you got the cpu fan connected to the correct place, the board has 2 one for the cpu fan andt the other for a system controlled case fan.

If that dont work check to see you got the power supply connected to the board propperly, there is a seperate 4 pin connector using 2 yellow and 2 black wires ensure it is correct.

Check your power supply

unplug the power supply and bridge the green wire with the black one next to it to see if it comes on. OR JUST CHANGE THE POWER SUPPLY TO SEE IF IT WORKS.

YOUR PROBLEM IS A POWER PROBLEM EIGHTER FROM A BAD CONNECTION OR A WRONG HOOK UP AND IF NOT THAT A BAD POWER SUPPLY

No respons at all !


I think your power supply cables is not able to start your B-board if your power supply is working properly then check mother board jack where you insert your power supply plug in M-board. Then you have to change or repair that jack where you insert power supply wire in M-board. With best regards M. Khalid Shaikh from Pakistan Mobile: +92-332-2631983
