Question PC reboots while playing any game

Jan 4, 2020
Hi Everyone,

I have an issue with my PC, while playing any games my PC reboots randomly, no error massage, no blue screens, just reboots or sometimes will freeze for a sek before rebooting. I tested the memory with windows memory diagnostics - no errors, Samsung Magician shows that everything is ok with the SSD. I used the OCCT5 to stress test the CUP and GPU and no errors or reboots.

I pulled the windows logs and it shows that The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

I have attached some screenshots from CPUID monitor and HWinfo.

Can anyone see something suspicious here, possibly with the voltages ? to confirm if this is a PSU fault ?

Build: Motherboard - ASUS STRIX Z270F Gaming.

CPU - INtek Intel 15-6600K

GPU - Asus STRIX GTX 1060 6GB Gaming

RAM - G.skill F4 3000c15 32GB

PSU - Corsair HX750i Platinum

SSD - Samsung 950 PRO 512 GB!ApyHFDhvTy7_wyzJg67vEiu6woCN?e=3wzzZl


From the 2nd picture, the +3.3V is not that good, because it shows only +3.18V, which is about 3.6% lower than the +3.3V, usually you want to see the voltages (+3.3V, +5V and +12V) are within +/-5%. And the problem maybe from the PSU.

First, use the DDU to uninstall the GPU driver, then reinstall it. Test the PC, if you still have the same problem. Next you may try to use the MSI afterburner to set the GPU power limit to 90% or 85%, or even lower from 100%. After that, test the PC to see what happens. If you can, you know the problem is from the PSU or not.
