Windows 11 CLOCK_WATCHDOG_TIMEOUT BSOD Recurs

Encountered CLOCK_WATCHDOG_TIMEOUT (0x101) BSOD twice in a year: stuck at login screen, then black screen with error. Frustrated with Windows 11 stability.

    Hey, I’ve seen this happen a few times, usually during login or when the system is under load, and then suddenly BSOD. This error is mostly CPU related, not random. Start with updating GPU drivers and check for a BIOS update. Also, crashes like this can lead to data loss , especially if it happens during boot.

    Update the BIOS and motherboard chipset drivers, and disable CPU overclocking in the BIOS
