So, earlier on tonight returned to my PC for a night of gaming (which is pretty much switched on most of the day) only to find it off. Strange, press the power button - hear a tiny clock and the fans move a fraction and nothing else. Unplug PSU, start again same thing a tiny click and fans move a fraction.

The mobo has some lights - the normal ones I'd expect to see, using the mobo start button results in the same thing. There is no diagnostic LED though.

Not sure if this a PSU - after all I get the lights on the mobo - or some other component issue. Is the PSU a good place to start?

edit: maybe just coincidence but the NZXT X62 failed a couple of days ago (pump). Reverted to air cooling - the temps have been just fine with a NH-U14S
 
Corsair rm800 - good call on the papercliip I'll give that a go, quick and easy to do! Late last night I removed the ram and gpu's but still had the same problem.
 
Paperclip test doesn't power on the PSU, so looks like a dead'un. Quick sanity check - unplugged from mobo, paperclipped, switch on PSU and nothing happens. It should power on fans, spin PSU fan etc. right?
 
Some PSUs run in fanless mode until they reach a certain temperature. If you've plugged fans into the PSU and then tried the paperclip test, the fans should spin.
 
Sounds like your powersupply commited powersupplyicide. RIP.
Get a new one and your machine should have you gaming again in no time.

Just want to rule out a powersurge having fried your PSU- are you using a quality Surge Arrester (such as a surge arrest power strip) or a UPS (uninterruptible power supply) or a surge arrester in your fuse box?

You should run one of these to protect yourself. Having a surge suppressor in your electrical panel in your home as well as for your computer power strip is good protection.

Swap these components out every couple of years as they do wear down with minor surges that happen all the time and offer less protection as time wears on.
 
Well, new PSU and still the same problem - the mobo isn't posting (or doing anything apart from lighting up the various LEDS - all look ok by the way) when you first apply power.

I've taken all components out, including the CPU tried applying power and nothing - no diagnostics or anything. So I believe I'm dead mobo land? Or any other ideas?

(I have the PSU wired up to a PSU - not powered but on the "clean" power supply side)
 
It's a Asus X99 Deluxe - everything is out including CPU, memory and GPU - literally nothing attached. It clicks the diagnostic LED's (where you get the codes) lights for a literally a split second and then it goes out.

I'll see if I have a spare battery for the CMOS. EDIT - no joy with replacing battery.

Tried that, there is no diagnostics codes coming up at all, zilch. Looking through the manual you should get a code for missing CPU / memory etc. It's not evening getting to that stage. But the pre-diagnostic LED's are coming up - weirdly.
 
Aye, dead methinks.

Since I don't really use the workstation aspect anymore (VM's etc.) but just the gaming I was thinking of jumping to a Z270 / 7700k platform - what do you guys think?
 
Bugger, after getting a new mobo and organising an RMA on the other - it's the CPU that's dead :( :( :(
