PC loses signal to monitor and freezes

[pepezinhoneto]

This has been happening ever since I upgraded to a legitimate copy of Windows 10.
Whenever it occurs, my monitor displays "No signal", my RGB keyboard keeps shining but the effects stop working (they remain static), Bluetooth devices are disconnected and no sound goes through. Basically my PC is now frozen until I push and hold the power button.

I tried updating Windows to the latest version, reinstalling Windows, cleaning my components and even tried booting up with 1 stick of ram at a time in case it was a ram problem as a friend suggested.

This is very unlikely to be OS related.
More likely to be a faulty power supply.
