Hello, About two weeks ago, a computer came to me straight from the German website - AMD Ryzen 7 5800X, MSI MAG B550 TOMAHAWK, 16 GB CORSAIR VENGEANCE DDR4-3600MHZ CL18 and a graphics card, i.e. GeForce RTX 3080 MASTER 10G from Gigabyte AORUS. When playing Europe Universalis 4, League of Legends or other less demanding games, there is no problem, FPS are huge, everything is fine. However, when I play Assasins Creed Oddysey after half an hour or hours of gameplay, suddenly the fans start to run loud and the monitor has no signal and no image is displayed. I play on ultra settings, when using MSI Afterburner the temperature is a constant 65 degrees, FPS at 60-80. After rebooting the computer in the device manager it shows error 43, which is a driver error. Reinstall on older versions did not help. What could be causing this computer behavior? Is it worth having the computer serviced first, or immediately under warranty?
