Entire System Crashes after some time

Hello guys! I’m new to Ubuntu budgie and havings serious problems with it.

I’m Using the 18.04 Ubuntu Budgie 64bits

Here is what happening : Everytime I’m on firefox or stremio my entire system just crashes randomly sometimes after I opened another ones after a few minutes. I’ve tried to reinstall from scratch, install the Nvidia drivers and nothing worked.

My Specs

i5 4960k
GTX 970

This only happens to Ubuntu, when I was using Solus it was just fine.

PS: Dual boot with W10 (Because of Gaming)
