Can't find the mobo on the asus site but think this may be the suppimentary gfx card power. Have you got a gfx card you canborrow or slave in in place of the current one as this seems like it may be dragging the power down and giving a power bad signal which then shuts down the PSU.

Alternatively what happens if you remove the GFX card and boot. Should get a beep code or similar for your mobo. This will cnfirm the gfx card or not.

Try with the gfx card removed and the connector conected then disconnected. If wont boot with the connector connected and gfx card out closely inspect the area around and in the conector for build debris on the mobo. Slivers of flashing from the case may be trapped on the mobo or in the connectors causing the issue.

Right I feel I am narrowing it down now. I tried removing components in turn and seeing if it would boot, and it still would not whichever component I removed.
However I found that if i remove the four pin 12v PSU connector next to the graphics card it will power up on the button, all the fans come on and the hard drives powr up, but no monitor output and I cannot turn off with the power button, I have to switch off the PSU.
If I replace the four pin plug and then press the power button it will then momentarily turn all the fans for a split second and then go dead and pressing the power button does not get even the momentary start a second time. If I then switch off the PSU and wait for the motherboard LED to go out, then switch the PSU back on I can get the momentary power-up again.
If I take out the graphics card the behaviour is exactly the same and also the same if I take out the PCI cards as well.

Slippy your going to need very deep pockets to buy one.

Been looking myself, but can't find much about the various makes.

I missed one last year at an liquidation/ bankrupt auction, went for about £400, at the time it was way over my budget.

OK that quite a few things to look at, I will post again when I have done the checks you suggest

No probs. Have you tried stripping the rig back down to the bare essentials? It could be duff RAM, a duff graphics card, a duff DVD drive or hard drive causing the protection circuits in the PSU to shut it down.

Alternatively, chuck a spare PSU in there if you have one and see what happens. You could try taking the PSU to a local system builder to have it checked out under load. Ask what they charge first though.

I am planning on pricing up a proper load tester for 600Watt PSUs at some stage just for giggles. I'd imagine it'd cost a lot more than most of us spend on a new PSU though. ;)

Cheers, Slipstreem. :cool:

Oh I should have mentioned that I shorted the two pins together that turn on the PSU. all the pins were at 0v before I did that. I will try to get the PSU properly tested before I go any further.

Thanks for your input slipstream, I do appreciate it.

Hmm... I suspect a PSU related problem of some kind then as the rails should all sit at (or very close to) zero volts with the PSU unplugged from the motherboard. :)

Well I found pinouts for all the connectors and checked there was the correct voltage on each pin, but this was with the PSU out of the PC and no load. I am not sure how to check it under load, I presume you need a special adaptor.

All the voltages check out OK with what? Have you tested the PSU under normal load conditions? :)

Is my Motherboard dead

Hi, newbie here, hoping someone can help!
I put together a system recently........

Asus M2R32-MVP motherboard,
AMD Athlon64 dualcore 6000,
XFX GF 7200GS, Supporting 512MB DDR2, 256MB Graphics Card
Kingston 2 x 2 GB DDR II 800 MHz CL5 1.8 V RAM
3x Seagate SATA2 250 GB HDDs,
Liteon DVD RW drive,
Pinnaccle PCTV capture card
Creative soundblaster card

It all went together fine, I installed XP Home and XP Pro 64bit in dual boot mode on one of the HDDs partitioned 125GB/125GB one OS on each partition. It was all going fine, then last night I was using it and all of a sudden it just went dead. It will not boot, POST or anything now. Not even a beep. The green LED on the Motherboard is lit but that is the only sign of life.
I have removed the power supply (Hiper type M 580W) and all the voltages check out OK.
I strongly suspect the Motherboard is dead, but would appreciate any other suggestions, I don't want to be sending it back to Amazon and it turns out to be something else that is wrong.
