Hello,
so i recently upgraded my PC from an GTX 1060-3GB to a 8GB Palit GeForce RTX 2070 SUPER Gaming Pro OC and a 750 Watt Corsair CX Series CX750M Modular 80+ Bronze. Since then my pc started rebooting after playing for short duration of time (30sec to 3-4min). It only happens in few games however like Planetside 2, Wolfenstein 2, Apex legends or cs go. In cs go turning on V-sync fixed the issue and I have not encountered any crash since. this did not help for other games. It is most likely not an overheating issue as games like Warframe or FarCry 5 can be played at max settings with a stream in on my second monitor with no issue. Also running benchmarks like Heaven Benchmark 4.0 or cinebench did not cause a crash. I have installed the latest Nvidia drivers. I just updated my BIOS aswell.
My system:
MSI MPG Z390 Gaming Plus
i5-9600k (4300Mhz)
be quiet dark rock 4
2x8GB Corsair Vengeance LPX (3200Mhz)
Palit RTX 2070s
Corsair CX 750M
Sorry for any mistakes english is not my first language.
I dont know what to do and my next step would be to send everything back, so any help is welcome
