Why is there a black screen after sleep mode?

Question

Iron

When I wake up the PC from sleep mode, the screen does not turn on, but the unit itself works (cooling buzzes). I tried many ways: I updated the video card drivers, unchecked the "Quick Startup" checkbox, in general, everything that needed to be done in the control panel has already been done. Already tried reinstalling. Previously, sleep mode worked, which means that the PC supported this function. How can I fix it?
