Kernel Power 41 Error

[jozefmery]

Hi everyone,

last week I upgraded my computer:
CPU: Intel i5-680
MB: Gb P55A-UD7
to:
CPU: Intel i5-4670k
MB: Gb Z87 UD5H
From that day, my computer turns off when Im playing games like Ac4.
It happens all of sudden, and after that I am unable to switch the PC on for about 10 minutes (maybe less I dont know exactly). When I press the button Its like trying to turn on but fails like 10 times and then turns off itself. The problem isnt always during the hardest events in game It happened even after i turned of the game. When I play Game like League of Legends it never happens, only harder games (harder i mean for the pc )

Other specs:
keyboard + mouse, headset and an external hdd (western digital my passport), nothing else is usually connected to the pc
Asus monitor 1920x1080
GPU: GB Nvidia gtx 770 4gb
Ram: 8gb(2x4GB) corasir cl9 vengeance
Supply: Tagan 700W
HDD: Wd 1 TB 64 mb cache (this is old and slow, changed it for a new ssd today, dont know how is it gonna affect it. The new ssd is intel 530 180gb)
Windows 8.

What I tried so far and ofc failed:

I constantly monitored the CPU temperature, once it happened when it was around 60°C.Im using stock fan.
I tried to use old CPU fan since I never had issue like that.
Completely reinstalling Windows.

I m guessing It may be some RAM issue or power supply or overheating, but im not sure. I am asking you for any help or advice that could be of help. Im really frustrated about this since it wasnt that cheap.
This is my first post on this site, if you think I put it in the wrong place, or you would need additional info to help, please let me know, I will answer asap.

Thank you in advance.

Looks like the PSU issue.
What make and model is it?

 

[jozefmery]

Its a Tagan 700W PSU (post now updated), I believe they dont have any other and it should be some piperock version or something.

My opinion about the psu is that 700 W isnt little and The problem wasnt occuring only when highest events occured as I mentioned above + Its isnt logical why it wont start right after it, because when the PSU fails it needs some time to recover ? I dont really know 🙁

Thank you very much.

It looks like the PSU should be able to handle this cards without problems. According to specification it has two 12V rails dediacted to power GPUs. However, you may experiment and unplug 6pin PCI-E power connector and use 2xMolex to 6pin (included with card). According to specifications molexes are powered from another 12V rail.

Your symptoms surely point to something overheating. When it cools down, you are able to turn on your pc again. My first thought is PSU, but maybe it is something else? Check GPU temps with GPU-Z.

GPU I don't think so. Why?
This never happened with the old CPU and MB + I'm using msi afterburner to check fps and temperature and it s always 60-70 c the gpu has three fanswhich are working about 50-60% under the highest load.

1 thing i tried but didn't test yet:
in bios i enabled xmp profile for ram and now it shows 1600 mhz instead of 1333 could that cause it? + Now i use the new ssd... Could the hdd.be failing?

And about the psu: could the difference in power consumption be so high so it fails under load?

Thanks, sorry for more and more questions 😛

I doubt it can be RAM or HDD. It could cause bsods, yes, but not immediate shutdowns.
