I have build this pc over a year ago. This is the 3rd one I have build for myself, I have build noumerous for others. In all those years i never had problems like I have now.
The pc crashed in october last year, i had just upgraded to windows 10 and was starting up a game, when for no apparent reason the pc crashed. I didnt have any overclocks running at that time. When i finally got my OS (windows 7) reinstalled, it didnt have any problems, so I updraded to windows 10, still no problems. It began from the point that windows did an update. From this point my pc posted and wouldn't load into windows, so I pushed the resetbutton. It posted and then loaded into windows. The next time i booted my pc it did the same thing, only now the famous blue screen appeared. It says there was some kind of driver error, driver_irql_not_less_or_equal, it didn't say which driver was corrupted. I looked online for solutions, and started updating the drivers on my pc. Tired of trying which driver was corrupted took alot of time, time that I didn't have. So I just settled with it, as it took only half a minute extra to boot.
Now, in the last week, I got another booting problem. Now the pc doesnt post, and constantly restarts, while still not posting. I ,then, have to shut the pc down and start it up again. Then it does post, but it needs 2 boots to load windows.
I have no idea what causes this, or how to fix this.

system specs:
Gigabyte Z97X-SLI motherboard
I7 4790k CPU (stock speeds)
Corsair H100i v2 cpu cooler
G.skill ripjawsX ram 4 stick from 4gb @1600Mhz
Msi r9 390 GPU
Samsung evo 840 250gb ssd
Samsung evo 850 500gb ssd
WD green 1tb
saegate barracuda 2 tb
Antec edge 750w PSU
BIOS verison: F8 2015-04-24
 
It would suggest that you have a problem with the cpu or memory in the system.

As you know if you get a problem with a system booting when you overclock the cpu, or the memory of the system if doing it manually.

Because you are pushing the cpu, or the memory in the system at a higher speed, particularly in the case of the cpu.
It requires you in some cases to add extra voltage to the cpu core voltage.

Even if you don`t have a overclock on the cpu in the system as it currently stands.
You should still check that the core voltage set in the bios is set correctly for the cpu`s default clock speed.
The same also apply`s to any memory of the system.

Both should be checked in the bios.

If the settings for voltages of both the cpu and the memory are correct.
Then as a test for the memory lower the frequency it runs at in Mhz to a lower value.
Test the system to see if it then posts first time, and consecutively.

If that fails to give a result.
Then you may want to increase the core voltage slightly of the cpu manually.
And the voltage slightly both in Mv power steps of the ram modules.

As a lack of enough power to the cpu core or memory modules, can cause booting problems when first powering up the system.

It can be the case, if the board fails to boot, and you get no bios posting of the board.
Or when for example the board posts, begins to load windows OS, but then resets mid way through loading windows.
Or the system powers off completely when also doing so.

The other thing to check is all of the hard disk drives and SSD drives you have connected to the system.
Sometimes something as simple as one faulty Sata data cable can prevent a board from posting.
Or a connection of it from the motherboard to the drive not being seated right in the connectors.

You can also try to re flash the bios of the motherboard, with the same Firmware version the board is currently running.
To rule out any bios firmware corruption, it does not happen often, but if it does
It can be another cause as to why the board has problems posting on initial first time power up of the system.

The last cause of what you are describing, is more of a case of a fault with the motherboard it`s self.
And the most common cause of a board not posting to bios when first powered on not working, but then after a few attempts is down to bad capacitors on the motherboard that may be failing.

The signs of a bad capacitor, are if the capacitor it`s self is domed on the top of it, where a good one should be completely flat on the top of it.
The most effected capacitors, or the most likely to fail or exhibit the visual signs will be ones where the board gets hot in set areas of it. Near chip set heat sinks, or Vrm of the board also with heat sinks on them.

That`s about all i can suggest.
But they are all the most common causes as to why a motherboard will, or may fail to post when powered on for the first time after being off for a few hours or more Barriegamer.

Anyway I hope it helps, take a look at all the points mentioned.

I have read through all the points you mentoined Shaun o. Apparently i got a corrupted bios of some sort, and the reflashing of the bios did the trick. The pc posted everytime i tried it, without any problems (I have tried it around 10 times).
That fixes the post issues, but you said this:
Or when for example the board posts, begins to load windows OS, but then resets mid way through loading windows.
Or the system powers off completely when also doing so.

It still resets midway through loading windows, sometimes even powering off for a couple of seconds.
