Upon pushing the power button of my PC , it starts up normally with the Windows loading splash screen and then the desktop. Seconds after I can see the desktop the PC just turns off. Clicking the power button just flashes the blue led color of the button. After unplugging and putting back power suply cables it worked. This happened about 2 days and I did the same thing with each day the procces of trying to turn it on being slower. I did do a virus scan with malwarebytes it it didn't find anything. Today I try to turn it on, turns on normally and then just powers off again. Unplugging the power suply, waiting, it always turned off after the splashscreen before the desktop with a black screen. I tried going in the boot menu but it wouldn't let me choose anything with the arrow keys, nor did it let me click enter. It just sat there and then turned off itself. Please help me.
