KERNEL POWER ID 41 TASK 63

That error, from what I find, is a CPU error and related to the CPU voltage.  

Thus, I would suspect the power supply is the problem.  

Unfortunately the only true way to test the power supply is to replace it with a new or known good power supply.

Thanks so much for your reply, I appreciate it.

otherwise what PSU brand or type that I can replace the original one with, how to know if it will fit correctly + the voltage and power and such please ?

And is there a way to test the actual PSU to see if it still givine enough power with the right voltage ?

Thanks in advance

It uses a standard "ATX" power supply.  I would get at least a 550 watt and preferably a "modular" type so unused power leads do not clutter the inside of the case.  

Here is an EXAMPLE of a modular power supply:

As far as testing the power supply, it would have to be measured under load for each voltage.  There are "power supply testers" but all they do is show a light for each voltage, they do not test under load or show the actual voltages.  Pretty much useless.  Unfortunately, the only sure way to "test" a power supply is to replace it with a known good one.  If the PC works with the known good one then the old power supply is bad.  If it still has a problem with a new power supply then obviously the old power supply is good.

Hi, thanks again, Im sharing with u, with the hope of helping me with any info i can use.

I have made a test by taking out completly the PSU and turning it on (alone) with no computer or any cable atached but the power cable of course.

And the weired thing, it been runing now for 1H straight, didn't turned off or anything !!
So after all, is it realy the PSU ?

That's not a fair test. The PSU may work ok all by itself, but fail when it's under load, eg when it's connected to the motherboard, drives, etc.

And I suppose you might have a CPU failure, if it's not the power supply...

Yes i see now, its logical, thanks

Im going just to add, that i have tested every single pin and cable from either the 24 Pin, Sata, or the 4 Pin cable (CPU Power connector) as well, with a volt-meter, and the output voltage is correcte.

On the other hand pls, can you enlighten me more abt the Possible causes of the CPU failure ! Will we be talking abt the CPU it self or just the motherboard ! And the solution if its so, thanks

Measuring voltage at every pin is still not testing under load, so that's not really a valid test, even if every pin appears to have the correct voltage.

The only way you're going to know for sure is to install a known-working PSU. And until that's done, the fault could be in the CPU itself or elsewhere on the motherboard.

A processor might fail and not detect voltage (or data signal) on one of its pins even though everything else is working correctly, so that might cause this kind of error message

Whatever turns out to be the cause, it's impossible to know for sure what might have caused the failure. Unfortunately, electronics do fail...

I had a similar problem with a Dell XPS-410 (running final BIOS and Windows-7 Pro (64bit)

Solution was to simply disable Sleep mode in Power Profile. 

From my notes ...

-------------------

Problem: Kernel Power Event 41

For the last few days, we find the machine has rebooted itself over-night.
(It does BSOD, and Windows is set to reboot on a BSOD event).
Windows says it has recovered from a serious error.
Events Logs show several of these, about the time machine would have tried to go to Sleep
- Kernel-Power Event 41 error

...

lots of trouble-shooting

...

Turned off whole machine Sleep Mode. Monitor(10 mins) and HDD(30 mins) is still set so those will still sleep.
- One less thing to troubleshoot. Machine will be either be ON or OFF (Shut-Down) for a week or so.

----------------------

Hope that helps

Leaving it off for an extended period could go back to heat related issues.  Replace the thermal compound as I suggested and see if that helps.

 

thanks for the reply and help

just that what i already tried what have suggested indeed :

- changed the POWER option and created a new custom power-plan where its to the high performance with no sleep or hibernate of the hard drive or else everything is off

but unfortunately nothing changed the same exact problem was always there

---------------------------------------------------------------------------------------------------------------------

PS :  I am just going to add that lately what I did noticed is that if  left my computer completely off for some time, like 24h or so, after when i run  it can hold on for quiet some time more than the usual, but of course the error will always happen, just that the duration is more imortant

i don't know if it's a clue some how about where the prob is

Yes indeed i have changed the thermal compound for either the CPU and the GPU, and cleaned very well the fans and all but still

But what i have noticed indeed right after changing the CPU's thermal past it holded for up to 4h10 which the longest duration by far ever since the issue started, and after it went down to a coupl of minutes again like before
-------------------------------------------------------------
But on the other hand, which is bizzar is that i use monitoring soft to keep an eye on different either power or heat related changes, and it doesn't show anything unusual (i guess) except if I didnt read that correctly.

I'm sharing with you two photos i have took on two differents occasion in less than a second before it went off

https://drive.google.com/drive/folders/10mqspDnUc-SxceNmTXwLB3bkdBskZT6m?usp=sharing
-------------------------------------------------------------

I know we are probably talking about a hardware issue more than a soft one, but Im curious enough a'd determinated in a way to do the diagnostic and find the real cause by my self as I beleive a have a certain technical knowlage ans such, before i start changin some hardwar componnements or else

I'm going back to an ailing power supply, but have you physically removed the video card and connected the monitor to one of the onboard video ports?

Try this next time you start getting the error message, immediately reboot (assuming you can) and press F12. Look for option to run the diagnostics. The diags you ran might pass when it's not hot, but something seems to be failing with heat and/or stress.

Is it on a good UPS (like a APC) ?

Hello RoHe
That's actualy a good sugesstion i didnt thaugh of before, but now thanks to you i did followed what you suggested to the letter

And it kept happening even during the test at different point each time. Sometimes it went thru everything check ok and then it went off, and sometimes at the end of the memory test (because its the last test anyways in the diag checklist).
I even did the test with one RAM at a time to see if its just a timing or because of the physical memory it self. But it kept happening randomly at different point of the diag

Hello Tesla1856
Thanks for you reply
To answer you questio, it is on Dell stock power supply (460 w), i havent added or changed any physical part of the tower it self
