ECS nForce4 A939 Rev1:0 will not POST

Posted on 2006-10-29

Client's computer would not fire up. I replaced the PSU, and now it displays the first BIOS screen (Main Processor...Memory Testing...Memory Information...) but will go no further.  There is no POST beep.  The keyboard is non-responsive - hitting DEL or ESCAPE has no effect.
I have replaced the keyboard twice, still nothing.  I have reseated RAM and disconnected everything including the harddrive.  With the RAM removed I get beeps, but with the RAM in place I get nothing, just the initial BIOS screen.
Replacing the motherboard will be a lot more expensive than just a PSU, and I don't feel that the mobo is necessarily the issue...but I can't find anything else to blame!
Does anyone have experience of this board?

If you have 2 memory sticks try removing only one at a time.  Also try reseting the bios and or flashing it to new

I have already swapped the RAM one at a time...I'll try clearing the CMOS settings and loading defaults.

i suggest starting with the minimum :
mobo + cpu + 1 ram stick, video card, keyb + mouse and power supply.
Can you access the BIOS screen now? yes? --> then connect the disk drive.
Does the disk spin up? does it boot? any messages?
You can also only connect a cd drive, and try to boot from that (use a bootable cd, like the windows XP cd)

I have already tried a minimal boot - no change;
The HDD spins up, but the pc does not boot;

It looks like it is time for a new mobo...
