Question Reboot when playing games on Chrome

[KB1968]

Have a Dell XPS 8700 (system details below). Recently upgraded the GPU to GEForce 1660 to get better performance on flight simulators. The upgrade installation worked fine only had to get a six pin to 8 pin converter cord for the power supply connection (still using the factory 450W PSU). After install the flight sim programs run fine with much better performance however when I play a game on Google Chrome the computer reboots. I have run stress tests from Dell and Intel and they have all passed. I have also checked the computer performance and the temperatures and memory usage are in normal operating ranges (both CPU and GPU). I also have upgraded to the latest BIOS and reloaded the GPU Drivers but it is still rebooting. I can't figure out why a simple game on Chrome is causing a problem when a much more aggressive flight sim program runs fine? Also, there haven't been any helpful messages in the event log. Any suggestions would be appreciated. Thanks

Reset Chrome?
Run Chrome with no add-ons?
Tried the same game with the new Edge (which is just a re-skinned version of Chrome?) or Firefox?
