Computer shuts down like power outtage, Kernel Power Error ID 41

Arc · 13 Jul 2013

Both the CPU and GPU are running hot.

Dismantle the PC. Clean everything inside. Clean all the fan grills including CPU fans and GPU fans, all the air vents so that it can blow the hot air out easily. While re-seating, apply new thermal paste to the CPU.

Then it is to observe if the temperatures are reduced or not. Post a similar speccy shot when all is done.

A 420 watt PSU is never enough. It will not be able to supply the adequate power that you need. Have a bigger one, at least 750 watts.

So it is hardware, as I suspected.

I guess there is no point updating another SF-Diag zip, but I will do so nonetheless

Yes, the diag tool zips are not needed ATM. Apply the suggested changes and then report back with another speccy screenshot.

I have cleaned both CPU and GPU's fans.
Re-applied thermal compound on CPU.
Should I also apply it on GPU? (the same compound)
At the present time I cannot afford a new PSU.

As you can see by the screenshot, CPU's overal temperature suffered a great improvement.
The same cannot be told about GPU (I still need to know the answer to the thermal compound question)

Edit: I'm sorry for taking so long to reply, I've been busy and only had the chance to do it now.
Edit: After correctly applying thermal compound to GPU, the average temperature values, after boot, are as follow:

NOTE that the image previous to the last had a similar temperature on Graphics, however it would always rise to the risk limit of 76-77º C;
now it's stable on 63-64º C temperature.

GPU is connected to the PCIe port, no scope to apply the thermal compound there :)

CPU is showing a better result now. GPU is better, too, but not the best.
It indicates either the GPU is failing to take the load properly, or the power supply is not sufficient (it is true that we already know).

Monitor the temperatures regularly. See if it is going beyond control or not. If it goes beyond control (the letters are showing in red) leave one side of the case open .... point a fan to the direction to blow air there.

Try to replace the PSU as early as possible.

And let us know how it is running now.

What I meant was applying the compound between the heat sink and the shiny chipset of the GPU, just like on the CPU.

I've had one side of the case open in a while (maybe 2 weeks).
Maybe I haven't played long enough, but ever since the cleaning, my computer hasn't shut down unexpectedly.
It seems that the CPU's temp was the one influentiating these shut downs the most.

Anyway, replace the PSU as early as possible.

420 Watts is never enough.

imho this problem is ms generated. I used to have this problem, and like other posters,
it only happened during gaming. when I turn my wifi adapter off, I never have this
problem no matter how much gpu power I am using. some will still have a problem
starting games with wifi off, but there is a workaround. open regedit, click on
computer, hit ctrl+f, type in servicelocation, just like I typed it, and wait for the entry
to come up. in the right pane, double click on games, and enter any valid path on
your c drive. this will fake out game explorer, making it possible to start games
without having an active web connection. after you make the change, you may
want to export that part of the hive to somewhere convenient so that you can use it
again after windows changes it back to the original update target.
