Question Screen goes black, peripherals turn off, but PC stays on ?

[annoyedAtAnything]

Hello, I recently build a PC and while it does work great and it can run anything so far, but sometimes while playing the screen goes black and there's no audio anymore, I see my keyboard turn off as well, but when I check the PC, the ram and fans lights are still running normally (fans spin doesn't go up), and it won't display anything until I long press the on/off button of the PC and then restart like nothing happened (while in the black screen, no error LEDs light up on my motherboard).

Specs:
Mobo: Gygabyte B450M DS3H
CPU: Ryzen 5600X
GPU: XFX RX 7600 XT 16GB
RAM: 2 x 8GB (clocked at 3200 using XMP)
PSU: MSI MAG A650BN 650w

I've checked temps and they don't even go more than 60° for CPU and 70 for GPU before going black, and sometimes as low as 40° and 50°
Event Viewer only shows an error that I forced the PC off.
Both old and new games, high or low settings, capped or uncapped fps, it's just really random.
Anything helps at this point, sometimes I even think my monitor could have something to do because everything with the PC seems fine, and if more info is needed please don't hesitate to mention, I appreciate any answers.
