hello guys , while i am using my pc the screen turns black and the red cpu led is working.
After pressing the restart button everything run smoothly but after some hours using my pc I have the same issue
(my cpu is working on base clock)
Amd ryzen 5 2600
MSI TOMAHAWK B450
and latest drivers
have you check temperatures on CPU and motherboard, just after the reboot ?
Sometimes CPU too hot do this.
Try to monitor cpu temp with cpu burn software running.
(CPU-Z to burn and Ryzen master or HWmonitor to see temp)
I have checked the temperatures of motherboard and of cpu (cpu idle 40-45, while gaming 75-85 stock cooler) but this issue happens when I do not do heavy work, for example while browsing. By the way thanks for answering.
