Looks like a power issue. You need a good amount of volts keep up with a good graphics card. I'd check your driver settings when you boot up the computer and check how many volts you are getting.
Yo, I just had this issue on my laptop. Here's what you do.
Uninstall the graphics driver through the device manager. Your screen may go off. Then, restart your computer. Windows will load a default display driver so the screen will work. Then, install the updated driver. Restart if necessary.
