Windows 10: PC Randomly Turns off and Restarts

As the title indicates, my PC has randomly restarted ie screen black, mechanical light up keyboard and mouse go black and then restarts. There is no rhyme or reason, most of the time I am just browsing the internet i.e a fairly light load. About a month ago, my CPU was replaced after it failed with a new identical CPU Hard crash, couldn't boot to BIOS at all. I am afraid that my new CPU is heading down the same path of total failure and I am really trying to avoid that.I should add in that this has only happened twice now since getting my PC back in early Feb after having repairs done f

PC Randomly Restarting after installing new Ram!

Tried your suggestions, but still had a restart! Also ran memtest overnight (13 hours according to memtest) and had no errors! Also ran Passmark Burn in test for a couple hours testing everything and had no errors or restart. Could fitting the new ram have triggered something to go bad like my mobo or psu?

 

Laptop Randomly Restarts / Turns Off and comes on with No Wifi

Thanks for the reply

I dont get any errors when the laptop restarts, but it happens randomly and instantly everything shuts down with no warning. Its not like a restart because it doent say restart it just turn off. And sometimes switches ot self back on.

I dont think I have downloaded any applications to cause the problem.

Te problem happens randomly, i think most of the time when im using the internet or using cpu heavy applications. But i think it happens randomly.

I tried the troubleshootin and it doest have the wifi adapter when it randomly shuts down. It just shows ethernet and bluetooth adapter. When i restart it again wifi works.
