The Issue

Moved my computer to a new house, and did what you always do after moving, which is plug everything in to check nothing was broken during transport. Everything powered on fine, got to the desktop perfectly, no problems whatsoever. Put it to sleep for the night.

Couldn't sleep, so I got up and tried the computer. It wouldn't start up from sleep mode. Turned it off, but now when I try to turn it back on, I get lights for an instant, and no fan power, before the computer turns right off again. With the PSU plugged in, I still get motherboard lights on. Help!

First; I would unplug your machine and then press and hold the power-on button for at least 10seconds, this will drain any residual power left in the electrical system especially the capacitors.

Reinstall the power plug and press the button to restart the machine, if the machine exhibits the same symptoms unplug again and open the case.
Make sure all connections are secure, your machine has taken a journey and even though it did start the first time the act of starting it up in its new environment could have caused enough vibration to jostle a connection loose. I would even go so far as re-seating the RAM sticks.

After checking all the connections and trying a restart, I'm hoping your problem is with the connections, but if it still exhibits the same behaviour, have you tried to use F8 to boot into Advanced Boot Options ?
I know it happens quickly, but try pressing that F8 key either repeatedly or continuously before you press the power button. If you can get to the advanced boot options screen try using "Last Known Good Configuration (advanced)", press enter or return key to finish booting.

Since you have motherboard lights, have you tried getting into the BIOS using the F2 or Delete key? If you are overclocking, return all settings to their defaults. Try restarting the machine.

What are your advanced power options for sleep? it would be better if you select hybrid instead of hibernate, see: Step 5 | Power Plan Settings - Change
You don't list it in your system specs, but what brand of anti-malware do you have installed?

If Last Known Good Configuration doesn't help try to get back into advanced boot options and try booting into "Safe Mode" to make changes.

Hello there, and thank you for your reply!

I've drained any excess power, reinstalled the power plug, checked all connections, re-seated the RAM sticks, swapped around the RAM sticks, substituted a new PSU + wires in, taken out the CMOS battery and put it back in again, unplugged the hard drive to check it wasn't that, and yeah, still the same symptoms here I'm afraid. I had suspected the problem was with the PSU because the clicking seemed to come from the power supply (and still does), and the fact that it just wouldn't boot, but now I'm thinking it's more of a motherboard issue? I wouldn't be surprised, with how temperamental this mobo's been.

As for the other options you suggested, I'm afraid I can't boot to test them at the moment, sorry!

I was a bit surprised to see a 450psu in a custom build, usually customs are no less than 600. The clicking could either be a fan misalignment or the psu is arcing against the case.

You say you do have a new psu in?? Then I would lean towards the Motherboard (MB) being dicey.

I threw the other options in, in case you were able to get the machine started.

Why the 600 generally? A safe threshold, I guess?

But yeah, I've just stripped the build down now and taken it out the case. On wooden/plastic surfaces, with just the psu, the gpu, the cpu, the ram and the mobo I'm still getting the same symptoms. Yeah, I think it's the mobo too. I'm guessing it -should- hopefully just be a straight fix by just getting a new mobo? Any recommendations? :P

Do you get any on-screen output at all if you remove RAM and video card and attempt to start? Maybe with a video card (I'm not sure if the i7-5820K has built in graphics).

And that happens with 2 different PSUs, when all components are outside the case?

And you can't even get fans to spin?

If the above is true, it's almost certainly a motherboard issue.

Yeah, all of the above is true. Must be a motherboard issue, looks like!

Yes, a safe threshold; No recommendations really, just figure out what you want to do with your machine and then get a MB that would be able to handle those needs, and don't forget about the wants in case you wanted to upgrade later.

Hello again! I downgraded to an old mobo, this time with an AMD processor and compatible board, plugged everything in, and I still seem to get the exact same symptoms. Very strange.

**EDIT**

To clarify, the only things that have now stayed the same are the 970 and the case. The power-source has always been the same, but this have been replaced throughout. Are we dealing with a faulty case here?
