Hey guys. I built my pc about 3 months ago. No issues until today. Basically random times my screens will go black, all usbs stop working, and even the case buttons dont work when this happens. But the pc is still fully on. All leds and fans. I tried taking my gpu out and just using the motherboard HDMI But there’s no signal. Is it safe to say this is a motherboard issue? I tried flashing bios and resetting cmos and nothing has helped. Thanks again!
