It has been very frustrating lately, almost all of my games crash if I play for more than 1 minute

I tried BO3, Forza Horizon 4, RDR2 and Stardew Valley, and the only one who didn’t crash was SDV

I tried updating and having the steamOS on stable version, I tried reinstalling SteamOS and all, it just makes this device so obsolete that I can’t play the games I own

Does anyone have this problem?
