Re: Asus M3A No Video On first Power UP
Posted: Sat Jul 05, 2008 10:13 am
Hello,
this is just to tell what finally made my computer with the M3A motherboard boot.
When I first time assembled my computer with the Asus M3A, it didn't boot up as expected. It started in stand-by mode. Power-light-diode was blinking and fan speed low.
I read in this forum that other people were experiencing the same problems as I. So it gave me some new energy and hope, that I would get my M3A to work as it should.
I assembled the computer several times before it finally booted. It took a few hours in all. But what might help other people to get their M3A to boot is the following:
The last time I assembled the computer I did two things that I didn't do the other times.
I cleared the CMOS as described in the manual page 1-25 - by moving the jumper for 10 seconds - but with this exception to the manual - that I left the onboard button cell battery in place. I did not remove it. My thought was, that there has to be some kind of electrical power to erase the CMOS data.
The other thing that I did with the last assembly before the computer booted, was - that the last things I connected before pushing the power button - was the power supply cables. The 4-pin and the 20-pins power cables to the motherboard, and the main power cable to the external jack on the power supply. Before this, I had installed the videocard and cable, sata-cables, mouse and keyboard etc.
So, clearing the CMOS with the onboard battery installed, and connecting everything else before connecting the power cables. After these two changes, my M3A booted and has worked fine since with no problems at all.
Regards
Karsten

Great thread here, I'm in a similar situation myself, no video, any help is greatly appreciated.
M3A
5000+ Brisbane
BIOSTAR GeForce 7900GS
x2 Kingston ValueRAM 1GB
500w Antec
It seems to POST, I get numlock and I can soft reboot from keyboard, I.E. ctrl+alt+del, all fans/lights work, power button shuts it on/off instantly. Originally I was getting beep codes of two long, pause, four short however through the course of my trial and error I reset the CMOS, now it is two long tones i.E. bad date/time from the reset.
The strange part is that my monitor acts as thought it is being sent a signal, it comes out of standby mode, however nothing appears. My thought on this is that the mobo is PCI-e 2.0 however this is not a PCI-e 2.0 card, does anyone know if there are legacy issues there?
Wikipedia has the following to say about PCI-e 2.0:
PCIe 2.0 is completely backwards compatible with PCIe v1.x. Graphic cards and motherboards designed for v2.0 will be able to work with v1.1 and v1.0, and vice versa. In some rare cases it is possible that a PCI-E 2.0 card will not work correctly on a PCI-E 1.0a slot. This is only limited to certain video cards.
Also I have tested with another 5000+, another M3A, another 7900GS another DIMM of Kingston 533 and an Antec 380w with the same result, all equipment last known good of about a week ago, the board is sitting on cardboard with only the PSU/GPU/CPU/One DIMM installed right now (I am shorting the pins to start it)
Any advice would be greatly appreciated.
