Hello to you all:
So I built this PC about 6 months ago. It was running completely fine for the first 3-4 months. After the 3-4 months I started getting random crashes where when I played game the screen would switch to a random color (Red, Green, Etc.) and then go black and the whole PC would crash. The fans are still all running but there is no display and there is a red led light on the motherboard. On the side of the light it says "CPU". I checked the Mobo. manual and it means that the CPU fails. I took it to a repair place and he switched out the CPU, Graphics Card, and Rams and it was still crashing. Therefore, I got a new Mobo. but it still has the exact same crashes. It only happens when I play games. Like 2 minutes into the game and it crashes. I also upgraded to a stronger PSU but it still crashed. I can't really think of anything. Maybe there is an issue with drivers? If anyone could help I'd greatly appreciate it 
SPECS:
Radeon RX570
Gigabyte B450 wifi pro
AMD Ryzen 5 2600
Corsair vengeance LPX 16GB
Corsair CX Series 550 watt
Have a great day
