PC has no signal to monitor and periferals [Closed]

Hello. So I was playing pubg and suddenly i have a huge frame drop. And i ve still played some games afterward to see if the frame drop will consist. It did and i decided to restart my pc. So now it doesnt give out any signal to the monitor and periferals. Mouse and keyboard. These used to light up on startup. I closed it using the button on the case and powered it up again but still no signal. What should i do.
Specs are : amd ryezen 7 1800x think so
Msi gtx 1080

Dont know the power supply either..

Thank you
first check the power supply. Then check the motherboard.
