i7 8700 Crashes under intensive renders

[keenwads]

I recently got an i7 8700 (I didnt get the K because i have no intention to overclock my CPU as I normally use my GPU to render) and when i tried to render a complex and high res model my rendering software instantly crashed, and this has happened multiple times. I checked my temps and my VRM and CPU temps were all normal and everything I have is on an SSD so im not sure what the problem is, I havent been messing with my DRAM clock speeds as well and any advice would be greatly appreciated,

Thanks in advance

(P.S, I have also been experiencing a weird situation which requires me to press my PC's power button twice for it to boot windows).

Hi, the CPU cooler is not that good but it should be okay. Can you do a Prime95 version 26.6 blend test run and tell me the temps to rule out the CPU...

I downloaded it but it ran indefinitely although my CPU performed fine, with temps ranging to mid 50s at max

(My CPU cooler is an AIO Corsair H80i V2)

P.S Thanks for your help so far

Looks like there is no problems with the CPU as those temps are spot on. What power supply are you using?
