Question about Samsung Odyssey Neo G9 - G95NA

Hello everyone, Is anyone aware of the following problem? In various games the game crashes and from time to time even blue screens appear. PUBG, Palworld, 7DaysToDie and others... Unfortunately, there are no error messages, not even in the event viewer. My gut feeling pointed to the graphics card (4090s), but it seems to be different after some tested. I tested another graphics card (3070) and this showed a similar error pattern. After upgrading and downgrading graphics drivers, Windows updates, Bios updates, multiple Windows restarts and other steps, I reached my limits... A colleague said it was due to the monitor, which sounds strange to me, but after several days of testing I can now say that it is somehow due to it. I don't have the problems with a different screen. In addition, I have no problems at all without gaming, even with this screen. It works brilliantly and error-free for the home office. It's only when I'm playing games that my computer crashes almost every day. Am I alone with this phenomenon, or has anyone had similar experiences? My setup: https://pcpartpicker.com/list/2hF3jH#compatibility_notes PS: Bios is up to date for 14th Gen CPU's... Thank you already for your answers. LG Djordje
