PC rebooting when loading certain games

[clemos]

Hi guys,

Got a strange problem if anyones got any ideas. Upgraded graphics card from Asus GTX 960 4GB to Zotac RTX 2060 6GB, but now when loading certain games (MotoGP2019 & 2020, Assetto Corsa tested so far) when going through the menu to load a game the PC will shut down and reboot. However I managed to load Call of Duty 2019 online and start playing, need to test further to see if it will eventually crash and reboot. To me it doesn't seem like a hardware fault e.g. graphics card, PSU, temperatures of both CPU and GPU are not high, all fans and watercooler pump are working. I've updated mobo BIOS and latest drivers, used DDU to remove and reinstall only the latest graphics driver with no additional software. Windows is up to date. Tried running a game with nvidia debug mode on, unplugged all other USB devices.

PC was built in 2016;
i5 6600k @ 3.5GHz
16GB (4 x 4) Crucial DDR4 2400
Asus Sabertooth Z170S
Corsair H100i
Zotac RTX 2060 6GB
Corsair CS750M
Samsung NVMe 512GB M.2 (OS/apps)
WD 4TB (games/data)
WD 4TB (backup)

Given you've upgraded the graphics card and nothing else, i'd suspect the Power Supply. I'd start there.. can you source another and test to see if the crash still happens?
