Asus X58 No start

Hardware Hub Motherboards
1

In the interests of saving the planet, I made the horrible mistake of shutting down my computer this morning.

Now it wont power up, it wont even try and boot or POST or spin a fan.

Asus P6T Deluxe v2, X58
PSU OCZ Mod-Xstream 600W

Checked front connectors, they're fine, no start
Removed front connectors, and used manual power switch on motherboard, no start.
Removed video card, no start still
Disconnected power supply and used a jumper wire to connect green to black - supply starts right up.

Motherboard is getting standby power - manual start and reset switches on motherboard clearly lit.
Machine has not moved or had anything done to it for 6 months.
In the past if I've stuffed up something like the RAM, or pushed the CPU too far, I get a power cycle - I've never had this board fail to pump the supply.

I'm going to pull it to pieces now, give it some TLC / clean and see if I can get it to work properly.

Any other Ideas? Experiences?

reseat power connectors to the motherboard.
24pin ATX and the 8 pin cpu powerconnector.

Thanks for quick reply, I did try that too a few times :(
Also attempted to start with mild-pressure applied to the connectors.

Edit: but I will keep trying this after a clean

try a power on with the ram in single channel (1 stick)

You could also try to take the mobo out of the case lay it on its cardboard box.
re-seat the cpu, install a stick of ram, gpu, and connect the psu.
And try to fire it up outside the case.

If the cpu fan is still not spinning at all, then i´m affraid that your mobo is dead.
And that would be a disaster, since it will probably very hard to find a new X58 mobo.

Ah damn it.
It was power supply related. I took the motherboard out as suggested, so I could poke/prod it.

But I was writing a reply using my wife's i3, and noticed how long her power supply cable was, after gathering permission I borrowed said cable and attached it to the motherboard, hit the power button on the motherboard, and it fired up the PSU - even with the RAM and 8 pin auxillary power disconnected.

Put it back on my power supply, and nada.

I can only guess (it's too late, and I don't feel like getting my multimeter from the garage) that the standby voltage from the power supply isn't quite high enough. So I'm off to buy a new PSU tomorrow :(

(part of me was hoping I had a good excuse for a Skylake build)

Lol, I always think its awesome being able to squeeze every last drop from old tech. Glad it wasn't the mobo. Do you game on it? Or do you use it for common tasks(Facebook/youtube/movies etc)

I used to love the days where I could build a new PC every year or so. But with other responsibilities, and the fact that it's still pretty brisk, I need a good excuse.

It's had RAM and an SSD upgrade, but still rocking an i7 930 2.8 (at 4Ghz though), and an ATI-4850.

I did use it for modern gaming when new, but these days the games I play on the PC tend to be quite mild as far as requirements go - stuff like Civ V etc. Best workout it gets is H264 video encoding, otherwise it's all facebook/youtube/movies.
