Question Display no signal from time to time, maybe ram causing the issue?

[EmielBakkur]

Hey, I built a new pc and it has worked fine so for a week, but a couple of days ago I noticed my screens suddenly showing no signal. I did a restart and everything worked fine again. But 3 days later it completely gave up on me. It wouldn't get past bios logo. I managed to fix it by reseating ram and GPU, but today I again noticed my screens showing 20 secs of no signal (did not have to restart though).
I am wondering whether it is the ram or GPU or something completely different. I need this computer to make online exams so having my monitors give up is kind of dealbreaker .

Sidenote: I have checked both monitors on other computers and they seem to be working perfectly.

Any help would be very much appreciated .
