Random shutdowns without error msg

[sonic72391]

So for about 2 months my computer has been shutting down at random without any error messages. I tested the gpu and the system would crash. I took it to a computer place and they said the same thing. I then contacted asus and 

got an rma, I did the rma got the gpu back repaired and it happened again. I got sent a replacement from asus and it does the same thing. I also reinstalled windows and this also happened and contacted Microsoft support. My house is around 50 years old so maybe electrical problems.

There is everything I'm using and its alot I guess for 650 watt. I think it may have been a power surge because my grandma was fooling with the main electrical shit and she shut it off and on. I 

just bought a surge protector and it still happens so I have no idea what the hell it is.

I have not uninstalled any drivers or updated my bios because I do not know how to

Have you gone to event viewer to see what the reason for shutting down is?

Power issue. It's either the PSU dying or the motherboard mis-delivering it.

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. The id is 41 and its something to do with kernel-power. I have gotten the psu checked and its fine but the motherboard may be the problem.

Also there are tons of errors and warnings in the viewer
