Kernel Errors

Hi there, a friend of mine has asked me what these random errors could be caused by and I am not too sure. He gets freezing and rebooting always when gaming but at random times and event viewer show these errors which I am guessing are prob down to his overclock. He is using Windows 10 64 bit and gets no other issues. I have tried looking online about this error and there isn't too much information to explain his problem. Anyone who could help him I would appreciate it.
Here is an image of a page of his errors.

He also has some other errors

Like I said I am thinking his overclock isn't quite stable, can anyone 2nd that opinion? or is this something else?

Kernelpower = certainly due to the overclock, either try bumping up the voltage a touch, or drop the OC speed down a touch, that would be my advice, but I'm no 8pack

Yeah i thought it was down to overclock too haha, ok I will tell him thanks mate.

It's quite likely that his OC is unstable.

The first thing to check is if he gets those errors at stock speed. If so, it's not an unstable OC. Kernel Power 41 errors are simply caused by an unexpected shutdown. You'll get one any time the system crashes or you do a manual reset/power-down.

The other errors are 0XC0000188 BSODs. These seem to be something to do with "Windows Readyboot". A bit of Google-fu might give you some more info. In all probability, it's a bad OC, but it could be something else.

Right thanks, he has just set his to stock and said he will run it today and see if the errors continue, the windows readyboot errors I have sorted for him now after looking at his system earlier on, they where a common error and easily fixed.
If the errors continue I will post back, if the errors stop completely we know it's what we think the overclock and I will overclock it for him this time instead of him doing it.
Will post back when I know more, cheers lads.
