Maximus IV GENE-Z won't post, no LEDs, no fan movement

Formerly working GENE-Z, now won't POST, no LEDs, no fan movement. Stripped down to one stick of memory in far slot, no video or disk, removed CPU, cleared CMOS, replaced CPU, still no luck. Tried different memory sticks.

This is all without any overclocking. All worked OK for a few weeks, no changes were made, suddenly refuses to boot.

POST succeeds maybe one or two times in 100 attempts. Runs fine then, but will hang up again when restarting or trying to wake from sleep. Perhaps slightly better odds after complete power-down overnight.

Anything else I should try before returning the motherboard?

pythagoras to me it sounds like power supply going bad,but really need more info like what cpu you have,power supply make and wattage,os you are using.if you try to boot up in bios will it go into bios and if you can get into bios is date and time correct?
try taken every part out of pc and putting on a piece of cardboard and see if it will power up out side the case.

Good call - right first time. I am now up and running with a temporary PSU cadged from an old server, and minimal devices on the Gene-Z. Reboots reliably now.

Was led astray slightly by the symptoms being initially similar to some issues on this forum.

Thanks for help.

Plug a laptop in and see what it says.

That sounds like the power supply to me too. I had one die on me before. The PC would sometimes boot, sometimes not. It would also shutdown at random times. I replaced the PSU and all the issues went away.
