Hi

I have bought a:
Mach4 NVIDIA nForce 2 400 Socket A ATX Mainboard (NF24-ALH)

I have everything connected. When I turn it on, everything boots for a few seconds, although the monitor doesn't even have time to turn on before the whole thing powers down.

Two red LED's are lit when the power switch is on, and stay on after it has shutdown.
Before I turn the power on, one LED is lit.
I have to take the power plug out, and put it back in again before I can have another go at turning it on again.

This has got me baffled, and there is no technical support yet for this motherboard!

Someone please help me!!
Many thanks

Gary

Hi and welcome. Sounds like it's shorting against the case. May as well take it out, hook it up on a flat surface and test everything.

Gary..
Do you happen to have the manual of the mobo? If you do , look under BIOS settings and see if you have a " SHUTDOWN IF CPUFAN FAILS".
It's possible that the fan that you are using now doesn't report the rpm to the mobo , thus making the mobo think that the fan fail , hence shut it down.
Might wanna try a different fan ( with 3 wires, yellow , red and black ) and see.

I have isolated a grounding problem earlier, and fixed it. However I am fearing it may have hurt the board.

Will try taking it out tommorow on a flat surface and see what happens.

Yep, I've got the manual but no mention of "SHUTDOWN IF CPUFAN FAILS". The fan has the 3 wires in question also.

Could it be a dodgey mainboard? The fact that I get some output tells me otherwise, is it worth me returning the item?

Thanks for your help.

At this point, if i was in your shoes ( and still under warranty ) ,instead of troubleshooting and hoping it will be stable , i would RMA it and get a replacement.
