Just purchased and built a new PC last weekend. Anytime I start certain games (so far) I get an immediate (less than 3mins max) and easily repeatable hard crash. All the monitors are solid black or green and you have to power off the system to reboot.
I've tried different drivers (using DDU to uninstall), different HDMI/DisplayPort Cables, Different Brand of Monitors (HP and Asus), and even different power supplies and memory testing (no errors). Monitoring CPU and GPU with HWInfo and CoreTemp and they never went very high due to how fast the crash happens.
I ended up uninstalling the video card completely. Installed my Nvidia 3060 TI and I have had no issues of crashes or issues running any games.
Returning the video card tomorrow and thinking of trying the 7900 GT but a bit wary of AMD video cards due to large number of complaints (googling) of this similar issue.
