Question My pc randomly turns off, but keyboard and mouse lights remain on


Jun 19, 2020
So, I built my PC around 2 years ago but recently (last month or so) i have been getting this problem where my monitors lose signal and go blank, but the audio from a yt video, my keyboard lights, and my mouse lights remain exactly how they were before the monitors lost signal.

It might not help but the specs of my pc are:

Ryzen 5 2600

16GB 3000mhz ram

Vega 56 8GB

700w evga bronze psu

1tb hdd and 240gb ssd

Admittedly, there is a lot of dust in my pc and I will clean when my new fans come. (in a week)
Is this problem due to the dust build-up?
