Question Encountering random freezes and pc crash while playing games.. Ez debug lights for ram and cpu flash

[Ryjin210]

Hi guys Good day, i hope you could really help me with my problem which is troubling me. i have a pc which i use for gaming usually. when i play a game specifically valorant sometimes a random freeze will occur. after 3 seconds the monitor turns black and the ez debug lights flash back and forth by the cpu and dram debug light but the pc is still on (rgb lights are still working and all fans are still spinning).

am i encountering an overheating issue with my pc? i recently bought a set of fans and the intake and exhaust of my pc case is cooler than before it was installed. i also tested my rams with memory diagnostic tool and memtest to check for errors but it didnt detect any errors at all. i hope you guys can suggest what can i do to fix this problem.
it occurs randomly though, my complete pc specs are the ff:

What are the idle and under load temps for the CPU and GPU?
