Question Monitor shows no signal

[Ssgsscj94]

I recently installed a new gpu in my pc. I uninstalled old drivers and installed new ones. It ran fine for 2 hrs and now I'm getting no signal to my monitors when I start up. The pc stays on and I can't turn it off without switching off the power supply.
