recently i have been running into an issue where i load into my desktop and try and start a game as it is loading before reaching the main menu of the game within minutes my screen blackscreens and im greeted to a message on my monitor screen saying “ No signal “ after this another message pops up saying “ please check your signal , entering power saving mode “ and after that i cannot stop this process of entering power saving mode and the only way for my signal to be acknowledged again is by fully shutting off my computer and turning it off however there are times where i do this and no power is going through my power supply even though it is clearly connected to power so i check my motherboard and see if my 24pin cable is the problem after i fully push it in it comes on but whole process occurs again and again like a loop , i tried to reset my computer and reinstall everything but i still run into the problem of my screen black screening , not only when i try and run a game but also when i try and edit on after effects.
