PC not stable

[spat55]

Everything is stock, I've ran Memtest86 for 4 hours with 4 passes without an error but sometimes my PC will just crash with a black screen and a kernel power 41 error. Some of the BSOD's I've had are IRQL_NOT_LESS_OR_EQUAL, IRQL_GT_ZERO_AT_SYSTEM_SERVICE SYSTEM_SERVICE_EXCEPTION

 

All these have the same module related to them ntoskrnl.exe but Prime95 isn't stable with errors within the first minute or a complete BSOD, I've flashed my BIOS from F11 to the latest F20b (Beta Bios) but it's still got the same issues, my thinking is either PSU/CPU or Motherboard but the RAM still has me guessing.

 

UPDATE: Just wanted to do an update on this, RMA'ed the 3700x and got another back it's been running fine with XMP on (which never worked on my old CPU) for over a week now so it was a dying CPU.

Specs ? 

Clear the cmos and then try.

Temps ?

Specs are on my profile, temps are fine, CPU isn't even hitting 70c same with the chipset hitting 72c. 3700x|x570 Elite|2x8GB Patriot Viper 3600mhz CL17|EVGA P2 1000w.

 

Wouldn't updating BIOS wipe the CMOS? I'll give it a bash because it's something I'd forgotten about but thought the BIOS update would be the same?

Technically yes but just to be safe 

Clear it

Try setting the soc to 1.1 and dram to 1.35 and then try 3200 and check if the instabilities go away.

The RAM is also at the stock 2133mhz without XMP running, I've got the BIOS completely stock so absolutely nothing is overclocked even Afterburner has no OC on it and shut down.

Well I had a look at kernel power 41 

And it could indicate a bad driver apparently.

Highly unlikely but try ddu 

And as I said above 

Clear the cmos.

Tried something, left everything on stock settings except changed LLC on both VCore and SOC to medium instead of Auto and it's now been Prime95 stable with small FFT's for 20 minutes, the frequency seems to be slightly lower because it's not boosting as high but it's been stable for that little amount of time. Some of the BSOD's I was having was in really light workloads with some chrome tabs open which made me originally think RAM until it was fine in Memtest86 but thinking about it if the voltage wasn't reacting fast enough it'd make sense for it to crash when changing workloads.

 

Going to continue messing around with things in BIOS as it's got me curious, opened an RMA request with AMD telling them of my issue, if they accept my RMA I'll probably do it even if it means no PC for a few weeks, it use to be stable with the stock BIOS settings.

 

I'll also run Prime95 for a good few hours when I sleep and see if it holds up for 4+ hours.

You are correct, clearing your CMOS is a complete waste of time.
