Have you tried to reduce/disable the CPU's overclocking as suggested in the other post? Are you using the stock cooler or an aftermarket one?
Too much temps will make the system to go unstable and crash, so I still need to know the temperatures for CPU and GPU: for CPU, max. 40 Celsius idle/ max. 65 Celsius load; for GPU, max. 80 Celsius. Maybe you should consider to change the thermal compound between the cooler and the CPU.
i am using silverstone argo 1 my max temp for 24 hours is about 75c i havent oc my gpu so it should be regular temps
also how do i reset my OC because if it happens again i prob just not OC it. Could be because my room is super hot maybe 85 degrees. And i had it OC to 4.2ghz for 1 year.
Reset the overclock: go into BIOS, put both the CPU multiplier and CPU voltage on AUTO. I didn't ask about the GPU overclock, but the CPU overclock, because you stated the CPU was running 4.2 GHz instead of the 3.4 GHz stock.
If you already passed the 75 Celsius on the CPU is a very bad thing cause, according to Intel, the max temp for the CPU should be 72.7 Celsius:

Also, did you clean the cooler and the fans? Maybe it is full of dust and the airflow is reduced. Did you change the thermal paste between the cooler and the CPU?
