My computer tends to restart when first I run a program and once it restarts once it usually is fine for the rest of the day. It is still very annoying because it has done when a game of league of legends has started, and even when I started an exam for school. I have tried changing my power supply, CPU, and RAM. None of this has worked. The only thing I have not changed is my RX 470 graphics card but it is the newest componet I own. In my event manager when a restart happens two things are of concern.
- A fatal hardware error has occurred
Componet: AMD Northbridge (I believe this is on the motherboard?)
-The system rebooted without cleanly shutting down. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
