My computer is crashing while gaming, and idling.

I’m having a problem with my computer where I can be doing anything, even idling, and my computer crashes. Windows 11 (home, OS build 26 100.3194) is my OS. After crashing, my computer soft freezes and in rare cases, restarts automatically. Usually I have to unplug the HDMI and plug it in again even after the automatic restart because it still doesn’t show anything on the monitor, then restart it manually. My PC just turned 2 months old with the components also being brand new. My computer is not overheating and it’s not a RAM problem. This I am sure of. Load has no correlation with the crash whatsoever but does seem to happen more often under load. I did a system reset after battling with it for about a week, but it was mainly to fix an audio problem, and hoping it would also fix the crashing issue. It unfortunately did not fix the issue. The weirdest part was that it worked perfectly fine for two weeks before the problem appeared (these two weeks being the two weeks after I built it), before the reset, and after the reset it started again about a week after. This is the part I cannot wrap my head around. Ever since those two weeks I have been battling the problem. If your still curious about the frequency of these crashes, they are completely random. I could use my computer for the entire day and it wouldn’t crash, another day it crashes just after 4 minutes. Other days it takes ~3 hours. Although these times seem specific, these are just times I can remember, the time is completely random. Usually, if it crashes one time, on one day, it won’t stop crashing until the next day, which I see if it crashes then too.
