Urgent help needed with X2 4400 and Asus A8N-VM CSM mobo

[Skinleech]

Hi

I have recently purchased an X2 4400 and Asus A8N-VM CSM motherboard, and am setting it up with 1gb 3200 ram that I already have. The problem is, I can't get the damned thing to work!

Everything is set up correctly, AFAIK, and the green light on the mobo is on to show power is getting to the board. However, when I turn on, all the fans spin, but nothing else happens - no image on screen via the on board vga or the on board dvi, no PC speaker beeps to indicate an error, and no spoken errors from the speakers plugged in to the on board audio.

I'd originall tried it with an Asus 300w PSU which I figured would be underpowered, but reliable, and I have also tried it with a brandless 450w PSU with the same result. I got the PC to boot once, and got into the BIOS to set up the machine - it hung after about 1 minute and hasn't worked since.

I've tried to clear the CMOS, and I also found a thread on the Asus support site where a few users have to reboot after a cold start in order to boot the PC up - I've tried that and it doesn't work either.

Help please! TIA.

Have you tried some different RAM?

Is there any posibility of a short circuit motherboard to case? Check all mounting screw... in fact you could remove motherboard from case, and lay down on safe surface, connect up ony essential devices (PSU, RAM - one stick and HD) and try that to see if it boots. I had to do that once.... turned out to be a duff PSU, but a short could also do it...

Yeah, sorry forgot to mention - have tried 2 sets of ram, 2x512mb Twinmos & 2x512 Corsair. Tried each set together, then individually. No luck.

Don't think so - have tried 2 cases also...

Hate to say this but a RMA on that MOBO may be the only fix

Just got a 4400 x2 myself and struggling also. I had problems booting (well didnt actually) when left on Auto on the cpu voltage. I had to put it on 1.425v to boot on my DFI NF4 SLI-DR which seemed strange ?
Try giving some extra voltage, it may or may not work.
Now to try to figure out the blue screens of IRQL not equal etc etc

That had crossed my mind - I've noticed a few threads around and about where these boards have been returned for on board card issues. Shame I don't have another skt 939 chip to test, or a PCI-E card.

I don't even get a picture to get to the BIOS to increase the voltage...
