[Help] UHD, HEVC, and stuttering...

[spoRv]

May, or may be not RAM.

Yet, I do not understand why cooling LED is so dimly lit now... I'm sure there is something related to it!

EDIT: connected directly, using a thicker cable, LED is a bit more alive - yet far from total brightness - and voltages on HDmonitor raised a bit...
Even if, for every reason, my house has not a "full" 220V, but, let's say, 210 or 200, the PSU should not be affected, right?

OK, it SHOULD not be overheating the main problem - I mean, it *could* be also this, but not the main reason why the PC shut down... infact, it happened twice when it was doing "nothing" (just surfing the web), and temp was 32°C when restarted (I guess around 40°C when shut down, not more)...

So, I'm almost sure the PSU is the guilty one - time to try a new one to be 100% sure, and strongly hope it will be "only" that one!
