Display, Keyboard, and Mouse lose signal; red CPU light on motherboard turns on?

[donald.wpic]

As the title says. I recently built this PC about a week and a half ago. Sometimes when I'm using it, the display loses signal and the LED lights on the keyboard/mouse turn off. I originally thought it to be a motherboard issue, but this most recent time I noticed the red LED CPU light on after it happened. It may still be the motherboard for all I know, but it may be the CPU? If anyone say some insight, I'd appreciate it. Not sure if I may have to exchange my parts or if I can fix it without that. When this happens, I literally have to force turn off computer to make the display, keyboard, and mouse to come back.

Currently using a Gigabyte AB350 Gaming 3 mobo and a Ryzen 1200 CPU. Thanks in advance for any help.

1. Clear the CMOS.
2. Go into Device Manager and look for any yellow warning signs.
3. What is your PSU?
