tech help for old Asus A8N

[niggles]

Hi All, thanks in advance for reading this, any suggestions are welcome.

I have an Asus A8N that has pretty much stopped posting with any regularity. The only thing I have done to it lately was that I swapped out the board from an older case that was making a huge racket. Moved the guts into an Antec Sontata case and now it purs... sadly it rarely posts. It'll power up but for the most part I get no beep and nothing comes on the screen. My wife will try it over and over again by shutting the power off on the PSU and then on again and then hitting the reset button. Eventually she'll get it to post... it'll beep finally and start listing what information it's finding in terms of connected hardware.

I'm not 100% sure that there are washers between the screws holding it onto the case spacers or not. I realised that today and then went to my parts vendor to get some more. They don't carry them but said that it wouldn't be that... Is it possible it's that, or is the Mobo simply pooched? Could anyone offer any suggestions?

Since you recently swapped the board from an older case to a newer case, I would pull the board back out and see if the board will post outside of your new case.

Disconnect all power connections, ensure all the power connections are not broken, then reconnect to the motherboard. Make sure any cards are properly seated. Make especially sure that 4pin cpu power connector is properly connected.

Double check the wires from the front case panel to the bottom right corner of the motherboard.

I ran mine till just recently, ran an old barton mobile 2600xp with the wire trick, overvolted and she ran up in the 3ghz region for years, had that Bliss 7800+ PCE>AGP card in it....memorries

OK, If I remember right that sounds like the symtom of the MB battery starting to go, pop in a new one and see if that doesnt fix things for you....

1. Make sure there are no standoffs installed that are not aligned with the screwholes of the mobo. BTW washers are bad because the screwholes are supposed to be grounded to the casing.

2. Take out the CMOS battery and try booting and see if problem goes away, dying batteries can make mobos not boot.

3. Unplug everything and replug again.

Thanks for the direction everyOne, I'm going to get parts today and will post back with the outcome.

I would for sure follow the suggestion made above about building and testing outside the case in order to rule out problems with the case.

And ditto on the CMOS battery replacement post. I've had that problem surface in the past, all because of a $3 part.

Good luck.
