Default PC Randomly Sleeps And Cant Be Woken

My PC will randomly go into sleep mode or at least my monitor will say that but the PC will still be on for example I could be watching a movie and the monitor will go black with the sleep message but I can still hear the movie and at this point I cant power off the PC with the on/off button unless I hold it down for 7 seconds or use the reset button and also nothing will awaken the PC at this point. Ive disabled letting the PC sleep in power and sleep settings.

Ive tried different monitors and its still the same, ive tried different video cards like RTX 2070 and GTX 1050 Ti but its the same, I thought it was my power supply Corsair AX1200i becase I couldnt change it to single rail mode so I bought another power supply Corsair HX1000 and ran it in multi rail first and then single rail but it sleeps in both modes. Ive got DDR3 ram using XMP profile.


I have an Asus Rampage 4 black edition motherboard
i7 4930K CPU 6 cores/12threads @ 3.9GHz
Windows 10 Pro

Ive changed the OS SSD and ran Memtest 86+ on the 32GB ram and it is good, The timings of the ram might be to blame even though its with XMP profile or it could be something with the motherboard but I dont know exactly what.

It's your monitor going into sleep mode, it says that when the data signal cuts. Problem is, why is the signal cutting.

does it go to sleep when you're actively using the mouse/keyboard?
