before that happens my screen would blink like dim then light dim then light. If i change the hz to 60hz the blink would go slower. Ive tried the win ctrl shift b <censored> doesn't work either. When my screen is black my mouse is frozen and i can't do anything ?
UPDATE: I connected my PC to my TV and it worked fine. Damn, so i guess it is my monitor.
Any reason why this could be happening and potential fixes?
EDIT: My monitor is Acer Nitro ED270
