CPU overheats, the reasons for failure?

For the beginning my specs:
Processor - intel i5 6600k;
Motherboard - MSI Z170A Krait Gaming;
Memory - Corsair Vengeance 16 gb;
Graphics card - Nvidia Geforce GTX 970 4Gb;
Power supply - Corsair RM750x - 750W;
CPU cooler - NZXT Kraken X62;

What's the problem half a year ago I left the computer and didn't use it at the time, it worked fine and doesn't overheat, and there was not any problem. Just yesterday I decided to play on and he was involved for a while and then abruptly turned off, I tried to join but it is either on and immediately off, or turn on and sent to the selection screen ( like in Windows log or BIOS, or reset all BIOS settings-a), I don't know that it overheats and tormented, then I saw the temperature and decided to change the thermal paste as soon as I changed it, the result is not changed, it still overheated. I decided to clean the radiator and fan it still overheats and gets 100 degrees, and in the end he made a scalping him, and the result what do you think ? Also successful has not changed, I do not know what processor I have and the cooling set on the top, I'm to be the water gets into the pump and it's not cooling down, but it's still hot, I don't know already what to do, who knows what's the problem ?

Clean all the dirt, put working cooling. There is nothing more to advise. The processor is overheating because its nothing cool, or not cool.
And with the motherboard can be the problem ? - enoch.Schroed commented on March 19th 20 at 08:43
@wulfdognot, it's not the sensor, I removed the cooling and everything was very very hot - enoch.Schroed commented on March 19th 20 at 08:46

Maybe the motherboard? visually, she's all right? the power supply circuit? conder? if you have a motherboard tester to check them all the codes for errors.

Best to all the factors to eliminate, it's your stone to test on another Mat.Board. If so, then stone. If not - most likely the motherboard. But about no health stone, it is very strange..
I'm thinking now to check the motherboard and cooling, and then I'll have to look, thank you for the answer - enoch.Schroed commented on March 19th 20 at 08:45
