PC sometimes wont Post

Right for the past month or so my PC will randomly not post / boot sometimes it boots just fine.

But other times the lights comes on the fan spins etc but the post code display remains dark.

It can sometimes be fixed by just turning it off and on again sometimes by turning off / unplugging the PSU and holding down the power button to "flush" it out.

Some times its fixed by removing the power from my powered usb hub.

although im not sure if any of those actually fixes it or if its just a coincidence that it happen to post / boot after doing those things.

Once the pc is booted it works perfectly fine to crashes no freezes no performance drops nothing.

 

My CPU is a Intel Core i7 4770K

My Motherboard is a Gigabyte Z87X-UD3H-CF

My PSU is a Corsair AX860i

And im using Windows 10

Well it does sound like a power supply issue. When you try to replicate this issue, can you switch off and then back on the power supply and see if that makes a difference?

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - dark mode Ubuntu (and Win7, cuz why not)

 

How many watts do I need? Seasonic Focus thread, PSU misconceptions, protections explainedgroup reg is bad

It dose but only sometimes its like 50/50 chance sometimes it dose nothing and sometimes it works just fine.

There has been times where the pc just works fine for weeks without any problems but it always comes back.

Check your 24pin cable.

Just check all cables and made sure none of them where damaged in anyway / also the connectors on the psu / mobo it self and i made sure they where all plugged in all the way the no post / boot still occurred
