Screen became dark grey all of sudden

Hi, I bought my gpu on January 2018 and never had this issue. The whole screen suddenly turned into dark grey, but I could still see my cursor as normal color and others really dark. I could perform Restart while this happened , although it was dark greyish. What is happening?

check the monitor connections. Check I/O on the GPU. power off, reseat GPU power on.

After restarting my PC , it's back. What could have happened there?
