Hello, thank you for replying.
Yes, my setup remains the same: an RX 7800 XT and a 9950X. As I mentioned earlier, even Windows doesn’t log anything at all about the error in the event log; according to the AI, it seems to be a kernel-level issue – it’s as if the system disconnects and doesn’t even log any events, but it always happens with Opera and YouTube. I’ll run the memory test as you suggested, although I don’t think there’s a problem there, as no other browser causes this fault.
I’ll follow your advice regarding Vivaldi and thoroughly check all the settings under opera://gpu.
Thanks for everything.
