So I recently got myself a R5 2600X, an Asus B450M PRO4-F and 16GB of G.Skill Ageis ram. I decided to play some RDR2 and after about 30 mins the game just crashed. It kept doing the same thing. I decided to run MemTest86 and it came with a few errors. I cleaned the ram contacts with alcohol and now i get no more errors. After the cleaning for about a day i had no problems. After that it has been crashing again. Also its not only RDR2. GTA V and other heavy-ish games crash like this. Also some more info - 1050Ti and a 480W psu. Neither the CPU nor GPU got above 65 C. I hope someone can help me out.
