fpu test Hardware failure

[hannibal]

Hi it is my system spec:

Cpu: 6700k intel

Ram: 2x8 GB gskill trident z royal 3600Mhz ( run at xmp 3600 Mhz)

mobo: ix code asus

vga: xFx Rx 580 gprs 8 GB

Power: cooler master 650 W

long short , sometimes when i playing games i get bsod Watch dog timed out error or game crash to desktop, i did not have this problem before and i did not change anything in my pc since i have no bios change or hardware change i mean, i tried reinstalling windows also and update driver etc ...

well after all of this i decided to check my system with aida 64 stability test and well here i am : FPU test after 10 sec stop and show me system failure error. ( i do not get bsod watch dog error during this or other stress tests) also i ran other stress testes for 30 45 min and no error seems like it just happen for fpu.

i just wanna figure out what part of my pc is making this problems. 

pls help since this is the most weird problem i had ever.

The most basic things you should check, system overal cooling, CPU core temperatures and power supply. But of course it can be basically anything including the CPU itself or the motherboard.
