Kernel Power 41 Crashes my PC

[emiliftz]

Hello
A while back i bought a R9 390 Sapphire 8GB and have been using it for quite a long time.
I never had any issues until recently I started getting crashes with error Kernel Power 41.
After reading through a lot of forums etc i saw that people were saying that it could be the cpu gpu psu and many more causing the problem.

So i decided to bite the bullet and buy a "new" gpu ( 1080TI ) and a new 700W PSU.

My pc worked without any crashed after the upgrade.

But here is the main issue and also why im writing here.

 

On my little brothers bday i built him a PC and used my old R9 390 completely forgetting about the issues i had with the Kernel Power 41 issue.

After 2 weeks of him using the pc with no issues he got his first kernel power 41 crash and i instantly knew that its the GPUs fault.

 

Now im asking for help trying to figure out if anyone on this forum knows how i could find the problem on the gpu and fix it.

Ive heard of Heatgunning the GPU but idk if that will fix it.
I know its all a high risk high reward type of situation.
 

Thanks for reading.

Kernel Power 41 isn't causing your issues, it's simply telling you what's happening. It's a report, not a cause. Essentially all Kernel Power 41 means is that "the PC shut off and I don't know why". Most of the time, it's due to a loss of power or something along those lines.

 

Did you re-use the PSU from your old build? I would be looking there, first.

honestly there isn't really a fix for that... heatgun, yes, if lucky it'll fix it "temporarily" for a few weeks, is that really worth it, possibly frying the rest of the system in the process? 

 

id rather get another more newish gpu tbh

Yeah, as @Skipple said, Kernel 41 simply means the PC(s) didn't shut down properly. The real error message that's causing the GPU to crash is something else. I used to have a defective RX 5600 XT, it would crash like you described. Checking the event viewer afterwards, I get WHEA 18 (Cache Hierarchy Error) errors, which since my CPU is fine, can only mean that my GPU is faulty. (I sold it off for parts.)

 

See what other errors besides Kernel 41 that you and brother's PC got when it crashed. If it is indeed WHEA 18, it means the GPU's broken.
