Can't fix BSOD errors

Hi.

In December I bought a new computer (built it by myself at home) and I have been struggling with BSODs since then. I ran several system checks, tried to re-assemble the whole pc, but it didn’t help.

The configuration is the following:
-Intel Core i5 6500 CPU
-Noctua NH-D14 Cooler
-2x4GB DDR4 Crosair Value Select (2133) RAM
-ASRck H170 Pro4S Motherboard
-2GB Gigabyte GTX 950 WindForce 2x OC VGA
-600W ThermalTake TR2 Challenger 80+ PSU
-240GB Crucial BX200 SSD
-2TB WD RED HDD
-Windows 7 64Bit Home Edition OS

The most demanding games I run is Diablo 3, Elder Scrolls Online, and Hots.
I installed the latest drivers for every component, I updated the Windows but it keeps freezing at random times. Usually I can play for hours, then suddenly I get a bsod or the simply Windows crashes. After the first crash it keeps crashing for several times, then I can use it again for some time… Once it also crashed whilst I was in the bios.

The messages were the following:
-A process or thread crucial to system operation has unexpectedly exited or been terminated
-system service exception
-system thread exception not handled
-memory_management
-IRQLNOT_LESS_OR_EQUAL
-CACHE_MANAGER
-Also, I can't update the bios (the Flash version wouldn't recognize the update file, and the Windows version just simply doesn't work)

I already tried these solutions:
-First I checked the temperature of the CPU: during load the maximum temperature was only 45-50 C°.
-Then I ran a memtest, it ended up with 0 errors.
-I checked the temperature of the VGA: I got ~77C° during games, so I used the oc tweaker, and set the manual fan speed to 100%. I got 70C° during games.
-Tried to remove the VGA and use the Intel IGP, got the same errors.
-Also tried to put the VGA into another PCi slot, the same errors occurred…

Since it crashed in the BIOS, I think it could be a hardware fault. I think the motherboard’s faulty, but I’m not sure. Any ideas?

Every help would be appreciated.

Oh wow, alright. So if you already did that then my second guess is RAM. I know you said you ran a memtest which came back with zero errors, but according to those BSOD errors, that's the second thing to look into. May try removing a RAM module at once to see if it persists and trying the other if so?

Those BSOD errors look like Windows is having the issue. I would run a repair on the operating system.

To be honest, this probably happened from Windows Updates you ran. One or more of the updates may have corrupted the Windows install and it's now blue screening out during a certain process. Seen it happen before, it sucks.

I know it will be a real pain, but I would reformat, reinstall and only install the necessary drivers you need from the manufacture websites.

I already tried that. Originally I upgraded to Windows 10, and the same errors occurred with and without the drivers. Went back to Win 7, and still the same...
But there could be a driver problem, too, I guess...

So I removed the RAM which was not blocked by the cooler (the other one cannot be removed unless I remove the cooler, too. but i don't want to waste the thermal paste if not necessary...). It's been continuously running for 26 hours!
I will keep testing. If the removed RAM functions well in an other slot, then I have a faulty memory slot on the board, right?
