Solved Kernel-Power error ID 41 (task 63) causing total PC freeze.

Here's results of full stress test of cpu, gpu, fpu, ram, cache after 34min with shutdown after I stopped test:

Here's results of full stress test of cpu, gpu, fpu, ram, cache after 34min with shutdown after I stopped test:

34 Minutes that sounds about right for a PSU to warm up enough to shut down just so happen i was doing the same thing and about the same time frame it would shut down so i am now sure it's your PSU

It's faulty you should try a different one and see if that makes a difference and also check your PSU fan if it isn't spinning after like 5 minutes of stressing that means it's not working or cooling off this is exactly what happens to everyone in this situation

 

[pczoran]

I did CLEAR CMOS and I started full stress test over an hour and all is fine. I'll let you know if everything is ok for couple of days , I returned C-state back to Enable just in case... :huh:

 

[essenbe]

I would see if you have a friend or someone who would loan you a PSU, just for testing for a few days. That would answer that question.

 

[ICIT2LOL]

Yes mate agree with the others on the PSU and you remember what I said about ok volts but dud current?

Just think of a near flat car battery - it will give you good volts but no grunt to turn the engine - just a rather simple analogy.

 

[pczoran]

It just happened again, it happens when I'm working in Camera Raw (Adobe Photoshop). When I moving cursor quickly from one to another point. And after 5-20sec of that, comp restart, everytime now. Because PSU or? I will try another psu tomorow...

 

[ICIT2LOL]

Ok Marc best thing to do mate as it could just be something gone south in that device - it has a self testing circuitry inside that governs whether the machine fires up the system and if the volts are not right or go down then it is an auto shut down it is called the Power_Good signal and that occurs at pin 8 (grey cable) on the 24 pin board socket.

It is detailed here
Voltage Rails - Power Supply 101: A Reference Of Specifications scroll down page 2 until you see Power_Good signal it will explain.

Now it might not be that but a possibility.

 

[pczoran]

How to check voltage with VOLTAGE TESTER (UNIMER) and to examine validity of board and psu? :huh: First I need to buy it.

On Monday I will be replace for new psu Cooler Master M2 1000w, same one. And if problem is still some, then is mb for sure... It is my opinion... :huh:

 

[ICIT2LOL]

Yep well any meter like that one can be bought so cheap these days and is quite good enough for what we need running volt checks.
Now I know it is a hit or miss affair but testing pin 8 and hoping to see if the pin signal falls out and you seeing it when that happens but is worth a try.

 

[pczoran]

Quick update!

I changed motherboard and the problems disappeared... Now, my new mb is Asus Crosshair V Formula-Z!

 

[ICIT2LOL]

Well then it just goes to prove that these things can be right out of field sometimes. But mate I would still check out that PSU after all the board is new and if the board was out of whack (old one) who knows if the problem may have been caused by some askew in the PSU - takes only a few minutes and what have you got to lose.
See my little ditty and use it to check the volts out
Using HW Info
You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic.
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
FOR OTHER COMPONENTS
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.
It is a good program to have on board so to speak for any of the component details.

 

[pczoran]

I took PSU to examination test in some pc servise, and the power supply is completely correct and without errors. After that I changed the motherboard and problems are completely gone ... Asus is Asus

 

[ICIT2LOL]

Good to hear but hang on to that program HW Info it is very handy to have and is not space hungry

 

[pczoran]

I have it , HWinfo, Aida64, HWMonitorPro, cpu-z, Open Hardware Monitor... I think it's a lot and enough

 

[ICIT2LOL]

Now I know I am a fountain of confusion LOL!! but one last thing you might like is this if you haven't seen it already - I use it on all my machines (6) it really makes the machine more efficient if you don't mind losing a little of the "bling"

In my case, "Disable ReadyBoot" brought about stopping the random crashes (id = 41).
Please try "ReadyBoob.bat".

No kp41

 

[essenbe]

The meaning of Kernel Power 41 is simply The system has rebooted without cleanly shutting down first. That can be caused by any number of causes from a bad PSU to a short in the system, or anything in between. There is no single cause for that.

 

[asifsound]

I think Win7/8 Kernel Power 41 issue is depend on OS.
If the same HW, and in different OS, perhaps the 41 issue will not occur.
I think the most dark culprit is "ReadyBoot" function from my experience.
I'm convinced that ReadyBoot has a bug.

To see is to believe.
If old HW circumstance can be available, please try "ReadyBoob.bat".

 

[essenbe]

The point is that every BSOD is different. If there was a bug in Windows 7 ready boost, every Windows 7 would suffer the same fate. They all do not. Every computer with new hardware does not suffer from Kernel Power 41 errors nor does every computer with old hardware suffer from it. I am happy you tried that and it fixed your problem, but that will not fix everyone's problem.
