I recently finished upgrading my PC today, everything runs fine I am able to browse the internet properly and watch videos. But every time I try to run a game specifically Rainbow Six Siege, the whole PC restarts with no errors message. I tried various solution which I will be listing down below along with my specs.
Solution I've tried -
Changing the PSU
Set it to Undervolt
Fresh install Windows 10
Disabling OC
Setting Zero RPM off
Setting frequency on both GPU and Memory to dynamic
Temp is usually 40 - 50c
Clean install my GPU with DDU in safemode
Download the graphic Driver 18.12.3
Specs
Gpu - AMD Vegas 56 Sapphire
CPU - AMD Ryzen 5 2600
PSU- Corsair Cx series 750 watt
Ram - Corsair Vengance LPX 16gb
Motherboard - MSI performance B450M
I've been trying to fix this for hours at the moment, but I will try to fix this in the morning any suggestion would be very helpful. Thank you for your help!
