Asus Maximus V Formula Problem

[M4to1987]

Hello,
I have bought this PC on september 2012 and I didn't have a single problem up until only recently, it started in the end of may 2014
Here is the setup specifications:
CPU: Intel Intel Core i5-3570K (o/c: 4.6 Ghz)/
GPU: Gigabyte GTX670OC-2GD SLI(o/c: +110Mhz/+500Mhz)
Motherboard: Asus Maximus V Formula
Memory: Kingston 16GB DDR3-2133
Audio: Creative SB X-Fi Titanium Champion
PSU: Seasonic 860XP 80Plus Platinum 860W
Tower: Tt Armor VO200M1W2N Revo
HDD sys: Crucial M4 256 GB
HDD: opt. 2x300 GB WD VelociRaptor 32mb cache
HDD: opt2. 1 TB WD + 1.5 TB WD + 3 TB WD
Sennheiser HD 598
Logitech G400s
Gigabyte Aivia Osmium
ASUS VG278HR 144 Hz Nvidia 3D vision 2

Everything is running just fine when I manage to turn my computer on, but the problem starts whenever I shut the PC down, and go to sleep, the next morning it just won't start up. It won't boot unless I plug the cable out of the PSU for a few minutes and after plugging the cable back in and reseting the bios setting through the CMOS button it eventually starts, but it didn't used to act like this, I don't know what could be the problem, it doesn't matter wheter I overclock the cpu or not, I tested it, it won't start after the night even if I leave the bios settings to default and I have to do this tedious procedure again.
I have the latest 1903 version of bios
Any help would be highly appreciated, thank you

Well I was happy that the problem was fixed, so I tought, but today after I wanted to start the PC after I was watching some football, it just wasn't starting, so I need to the mentioned tedious procedure of unplugging the cable for 5 minutes, reseting cmos and setting up all the bios settings again.
So the problem still persists 😞

If possible see if you can borrow a PSU and if the behaviour is with the different PSU RMA the motherboard.

Hmm, I don't have another free psu, I will do a cleanup of the whole PC though, remove all the components and clean them with pressurized air and reinstert them back again....Maybe dust could be the problem? I will give this a try. I will do that on the weekend when I have more free time, I will return here with the results HiVizMan. Thanks for the help so far

HeY HiVizMan,
so I managed to make some free time at the start of the weekend to clean up my pc.
I basically dismounted everything from the ground up, tore everything apart, took cpu off from the socket, reapplied the thermal paste, removed the mobo from the case, very gently cleaned it off of dust, cleaned the cpu radiator, the gk radiators, all the optional case fans, literally wiped all the dust from the filters and also cleaned the psu completely with compressed air, man there was some magic dust in that box, it's unbelievable that after almost 2 years so much dust can be gathered in a single PSU unit.
So after removing all the pesky dust from the components I managed to assemble the pc back to the working state and wanted to try if everything was working now properly as it should.
But to my disappointment the pc wasn't starting when I pressed the power on button. So I power cycled the psu and it almost instanteniously powered up without me pressing the power button on the front of the case....So at that moment I've become very suspicious the problem can't be in the pc or the components, but in something else.
So I plugged out the apc power surge protection from the main socket and plugged the psu power cord to another apc surge protection I had in my house and the pc started without a problem when I pressed the power on button in the front side of the computer, without me having to do any powercycling on the psu or clearing cmos or anything. As it stands now, the pc is starting now as it should be, at least it was for the whole weekend.
I will test it more when I come home from work tomorrow afternoon to see if the pc can start from the cold boot and give you some more feedback if the actual power surge protector unit was the main culprit in this case.
If that might be the case,then I couldn't be more happy, because I don't need to RMA the motherboard or psu or anything and that would be perfect scenario for me.
I have my fingers crossed and sorry for the long post.

[HiVizMan]

That is outstanding news mate. Well done.

[M4to1987]

Allright,
Iam back, sadly....it turns out the other apc surge protection wasn't good either, because when I came home from work today, the computer wasn't starting again, but strange thing happened, when I hit the power on button, the light on the keyboard has been lit, so were the power and reset buttons located on the motherboard, and the red led stripe that is integrated into the motherboard, however the PC wasn't starting. So I plugged the PSU cable directly to the power socket and everything worked, but this wasn't happening for the whole year and a half when I had the old APC surge protection inbetween the PC and the power socket to protect my hardware...
What can be the issue here, please help me HiVizMan

*EDIT
Well it turns out the problem isn't in the apc surge protector, it must be something else because just now I turned off my PC and when I wanted to turn it on , it just wasn't starting, again when I hit the power on button, the light on the keyboard has been lit, so were the power and reset buttons located on the motherboard, and the red led stripe that is integrated into the motherboard. So I had to unplug the power cord and then replug it and then power cycle the psu again to get it started. Iam in despair right now...

[HiVizMan]

Please try and connect directly to the wall socket for a few days. Leave the current protection up to the board and the PSU.

It is sort of sounding like a motherboard issue, but that may simply be your PSU not functioning correctly, really hard to tell at a distance. So try with connecting directly to the wall socket.

if that fails to do anything RMA the board and/or the PSU.

[M4to1987]

Iam just doing some tests.
Iam shutting down the pc and powering it back up with pressing the power button, and almost everytime when I try to do this on the 4th repeat the computer fails to start but the light on the keyboard is lit, so are the power and reset buttons located on the motherboard, and the red led stripe that is integrated into the motherboard.
This can't be a motherboard problem, this must be something else.

*EDIT
Nah, scratch that, it's doing randomly, sometimes the computer starts and is booting and sometimes I have to power cycle the psu multiple times in order make the PC to start.

Just found this forum thread on another website from january 2014

It seems lot of the folk with similar PSU from seasonic, the X series are having the cold boot problems as me
It's more likely now I have to RMA the PSU.
