When I press the power button all of the fans come on, the hard drive sounds like it engages.
Why do you have the HD plugged in when trying to POST to BIOS for the first time? Unplug it, there is no need for it to get to BIOS. I would unplug everything except CPU/HSF, 1 DIMM RAM in slot one, and video card and try getting to BIOS. If you have onboard graphics, you might try without the 9500GT. With the system 'bench tested' like this, if it still will not POST to BIOS be sure you have a working speaker attached to the MB speaker header. Remove all the ram. If you get no beeps indicating there is no RAM in the system, you have a bad MB or CPU.
I have a M3A78-EM and had the same problem, in my case it was a REALLY strange problem with my ram. (2 x 2)Gb Kingston HiperX Cl4.
First the pc will not boot. I tried removing the slot "B" RAM module and no boot.
Then i changed slot "B" with slot "A" and it booted with the two modules but BIOS will only detect 2Gb instead the 4 that i had installed. I thought that was one of the RAM modules that stopped working.
Then i tried the faulty module in another pc and it worked!. I run Memtest86+ from Ubuntu for 6 Hours and no problem.
I put it back to my pc and it worked, Bios detected 4 Gb of ram, cpu-z 4Gb and now it works just fine. I run OCCT Ram and no problems. I dont know how i solved it but now it works
I actually built it right the first time and had no faulty hardware.
My wife's old computer had an old video card (ATI9800Pro) with a VGA port that was hooked up to the monitor / VGA cable.
We used the same monitor in this build however I tossed the VGA connector cable and replaced it with a DVI cable.
The PC actually booted on my first attempt. The problem was that my wife's Samsung monitor did not autodetect and switch from Analog to Digital so it remained in sleep mode and did not turn on.
I swapped monitors and the computer posted fine.
Swapped back, got messing around with the buttons and found a button that switched the input setting from VGA to DVI. Once I did that I got a visual on the POST screen and from that point my wife was able to install OPENSUSE 11.0.
My wife is happily running on her new LINUX computer now.
@basa - This type of problem can also be caused by forgetting to plug in the 4-pin CPU power connector in addition to the 24-pin motherboard power connector. There are multiple posts on here every day where that is the reason why the board isn't posting.
You should start your own post on this and list your complete computer specs. I'm guessing you mean BIOS update when you say "bias upgrade". It's a little hard to diagnose a problem without knowing what hardware you're working with.
Thanks for the help, have tried one stick of ram and also swapping them about as mentioned above, but still will not boot,

Hi, I think that I have the same problem. I have an Asus M3a78-em motherboard with AMD Phenom x4 9750 and 4gb of Kingston Ram.
Every morning when I start up my pc, it doesn't boot, the power led, fans and the mouse works, but the screen shows violet lines and nothing else, then I restart it and it works without problem.
Can somebody help me?
pd : Sorry for my english, I am from Argentina!! : ).
I just bought a Asus pq5l-em motherboard. Same problem here. No image on DVI cable. D-sub works fine.
After read a guy post here, i can confirm that. I just noticed my samsung monitor dont autodect the digital signal. I had just to press "source" button on monitor and there is it! Digital image was waiting for me.
my lcd is Syncmaster 2232bw.
I dont know if its a issue about samsung or the onboard video card. I had tried several differents computers in that lcd monitor and signal was being detected flawless... until now.
Anyway. Its working 100%. Sharp and no flick image.
Just to let u know. If you are sure monitor dvi imput works and u are not getting image and have that funny massage "analog no signal found" poping on screen, just change the lcd source manually with just a finger touch on a button. Easy as a pie.
