Windows 7: Event 41, Kernel-Power

I've installed Speccy, but in the summary it shows me "CPU 5C" whereas "Motherboard 20C". Thought the PC runs only like 5 minutes so far. Funny, even the HD's are shown with 23C.

Power Surge Protection, well in Europe i didn't need one. We had very few fluctuations in electricity, here i think every time the Air Conditioning outside jumps on, the power here fluctuates.

For the Voltages, i suppose the readings have to be in Volts, right? I did search the whole Bios menu, didn't find anything apart from
Core VID 1.4125V
Current Core VID 1.392V
Also, i still have the original manual, on the same page 24 it shows me the Cell Menu, as you said, but just like in the online Manual my Paper Manual shows me a picture of the Bios Cell Menu, and the three options:
CPU VDD Voltage (V)
CPU-NB VDD Voltage (V)
DRAM Voltage
All those three are set to "Auto" and greyed out.
But i will take a look again, lets see if i overlooked something.

BTW, how do i check, what did get damaged? I mean, if the CPU got damaged, how do i check it? I just hope, that not half the System got damaged.
The past few days i didn't experience the System to just Hard Hang.

It's possible the monitoring programs can't read your CPU temps correctly.
After your computer is warmed up, re-boot into BIOS and check the CPU temp there, if it shows it.

Go to the voltage section in your BIOS and set them to 'Manual' this should allow you to see a voltage number, post them here.
CPU VDD Voltage
CPU-NB Voltage
DRAM Voltage

We'll go through the settings and testing process step by step, then we can determine if there is any damage.

Hi Dave,
The PC was running the whole day, i played Farcry3 for quite some time. Just before i read in the Bios 25C, while before the reboot into Bios CoreTemp and Speccy told me 3C.

So for the Bios and Voltage. Do you mean Volts, or Hz? Earlier i searched for "Volts" in the whole Bios, but found none. The downloaded Manual is the same as the Booklet i have from the Mainboard. In the Picture that is in there about the "Cell Menu" you see 2 sections, one at the top and one at the bottom. The one at the top states:

Current CPU Frequency 3.60GHz (200x18)
Current DRam Frequency 1333MHz
Current CPU-NB Frequency 2000MHz

Is that what you meant buy Voltage? Would have helped if you told me you search for GHz/MHz values, i searched for Volt ~.~".

Frequency is in MHz and voltage settings are in (v) volts.
We need the voltages settings, not the frequency MHz.
Page 24 of your manual, at the bottom of the picture.
Scroll down when you are in BIOS.
CPU VDD Voltage
CPU-NB Voltage
DRAM Voltage

That's a problem. That where the place, i first thought of, when you said Volts. The problem is, that there is see only(like in your picture) "[Auto]".

Pressing Return does nothing, on the right where usually some explanation is i see no Volts, apart from DRam Voltage where it says "Auto = 1.50".
For the other two (CPU VDD & CPU-NB VDD)i can only speculate, as the only way to change those is through the + and - buttons. Pressing from [Auto] the - button shows a red "1.5500", and pressing the + from the [Auto] shows a white 1.1000, another + adds 0.0125 increments, so 1.1125 > 1.1250 > 1.1375 and so on.

Can you confirm:
The CPU VDD is showing a red "1.5500" as the next choice?
The CPU-NB VDD is showing a white 1.1000 as the next choice?

I can't recommend any setting adjustments until I know what the current voltages are.

I can confirm, that all three stand on [Auto]. Just like you can see on page 24. Both show if i push + (plus) it jumps to 1.1000, and if i push - (minus) from the [Auto] setting, it jumps to a red "1.5500". I suppose 1.5500 is the max value, you eventually get there if you press consistently long enough +, as it's going up in 0.0125 increments.

But, one more thing. I didn't have a lockup as before for quite some while. Also when i looked into the Event Viewer, all past Events of Kernel-Power where gone, erased, thought i didn't manually erase anything, nor did i clean up the Harddrive C: with any software or anything. That's very strange.

Leave CPU VDD on 'Auto'.
Increase CPU-NB VDD to 1.150v.

Check for stability, let us know if it's stable.

So you think if i set it to that Voltage, then the Ram will work correctly in Memtest as well?

It's a good place to start, if it's not stable we can make another adjustment.
This has worked for many AMD motherboards.
When you have 8GB RAM most of the time you need to bump the IMC (CPU-NB VDD on your motherboard) voltage up a little, the more RAM you have will require more voltage.
