Hy fellow readers,
I`m not sure this is the right topic to post this?
But i see a lot of topics about Random restarts of the Pc.
Two weeks ago i unfortunately had the same issue,
after upgrading to a Turing GPU ( i had a GTX 750 Ti).
First I swapped the GPU (gtx 1660 S) to another one and the problem persisted.
Swapped again to an GTX 1660 ti still to no avail.
Then finally i replaced it with an RTX 2060, but as you would guess,
still the same problem.
So after some reading and different trouble shooting i replaced my 80+ gold 650Watt psu
for a tier a 750 watt 80+ gold psu (Corsair RM 750 (2019) ).
but as the issue was now far less it however still prevailed.
I finally found the real culprit .......
in the bios of my gigabyte Z97 mainboard there is an option called DMI gen 2 speed,
for some reason it was set to "auto" .
should be no problem as assumed, but after setting it to enabled all the random restarts are now gone.
just my two cents, ( hope for some with an issue like this it can help)
