my screen has flashing blue light and yellow pixel block while gaming

[bkrites13]

hi. for some reason while I was gaming on steam my screen suddenly started flashing this blue pulsing light and has a yellow block that keeps flashing in different areas on my screen. don't know what the issue is. just happened within the last 10 min or so and don't know whats going on.
Update: now my screen has green flashing lights as well and screen goes completely yellow sometimes. don't know if it helps but the game I'm playing is called NieR: Automata on steam and I have an ASUS ROG product number 00325-95972-76841-AAOEM with an NVIDIA GEFORCE GTX 960M graphics card. any help would be greatly appreciated

Monitor temps with HWMonitor, see how high it gets. Could be overheating, could be a failing video card.

How do I know if the graphics card is failing though?? What is the safe temp for the graphics card and the laptop itself??

Seeing those image issues is a sign of the video card failing, what you need to do is rule out everything else you can so there is only one possible thing that can be wrong. I would say 90C for both CPU and video card is too hot.
