Windows 10 Game Freezes with Blue Screen Termination Code UN

The computer froze twice while gaming, accompanied by a buzzing noise from the speakers. The case's power button failed to shut down the system (ultimately requiring a hard power-off by unplugging the power cord). After the first freeze, it automatically restarted when plugged back in. Shortly after resuming gameplay, it displayed a blue screen with stop code UN, and the restart progress bar became stuck. Please advise on the cause of the malfunction and the solution.

    Sometimes, browser cache or extensions cause issues. Clear cache or try accessing the router using an incognito/private window. Alternatively, try a different browser (Chrome, Firefox, Edge).

    Disconnecting and reconnecting the graphics card can help resolve loose connections or potential contact issues.

    Overheating CPU, GPU, or other components can cause system freezes and crashes. Failing power supply or inadequate cooling might lead to instability.
