Hi, as you can see in the title I ran the "Intel Processor Diagnostic Tool" and got a fail at the Prime Number stage.

I decided to run this tool, because since last month my PC has shutdown randomly and when I open Event Viewer it gives me Kernel Error 41. I have run memtest with both of my RAM sticks connected without any errors. I'm now using only one stick of 8GB of RAM, and the PC seems more stable, but I have run memtest in each of the slots of the motherboard without any errors, except for the second slot that doesn't seem to work. I have checked temps and everything seems ok. I have changed the PSU.

My specs are:
i7-8700k
RX 580
16GB RAM (2x 8GB) (currently using only one stick)
2x SATA SSD
2x HDD
Tempest Gaming PSU X 750W
ASUS B360M-A

No crashes during gaming, only when using Discord or Opera.

I can't try the CPU onto another motherboard, i have spare RAM so I could try other sticks and have another PSU.

My question is if it is a CPU problem or it could be an issue with the Motherboard. Also if there is anything else to check.

Thanks for your help.

Prime calculations are used for a lot of security encoding algorithms. But it's also a power hog for a lot of CPUs. That's why prime 95 is used as a stability test tool for CPU overclockers.

Please grab Prime 95 and run it and see if you see any large variations between the processor core process times for calculating primes.
I solved it by changing drivers. It seemed to be a problem with the CPU integrated graphics drivers. Now i get a pass at the test. My PC continues crashing but it isn't CPU related. It must be the motherboard.
Also the fail at the Prime Number stage was only appearing on the GUI, in the log the Prime Number test shows as passed. Nevertheless, thank you for your help.

Ok, thanks. I managed to get a pass in the test after changing some drivers. So now the only thing that looks broken is my motherboard. Is there any chance it has any solution without buying a new one? As I said before my PC crashes randomly and second RAM slot doesn't seem to work. Is there anything left to try or I am doomed?
