Windows 10 shuts down, but PC won't Solved

    If you disconnect all hard drives, and powered up the computer, wait for the no boot device error, then press & hold the power button, does the power supply shut down ?

    Alternatively if you have other bootable media, and you boot from that, are you able to power down ?

    Might be helpful to isolate MB, processor, power supply apart from Windows.

    I had to disable in BIOS, the onboard Broadcom Netlink Gigabit ethernet NIC.
    Doing that returned normal Power supply operation. Sleep, Shutdown, Hibernation, now normal.
    The pc, being wireless, did not have me suspecting the onboard NIC & W10 CU compatibility problems.

    Find some weird things in computers.

    update: I did several new things in trying to locate the problem

    • successfully flashed the BIOS from 2.0 to 1.3
    • left the BIOS settings mostly at defaults
    • RAM left at default 2133mhz, for now, not running the XMP profile (3000mhz)
    • unplugged USB printer from motherboard

    So far, since flashing the BIOS to 1.3, i haven't had any failures (2 shutdowns, 2 sleep, all successful). Though I've learned this doesn't mean much - i've had strings of successes before, only for it to fail again. But it's a start.

    If after 3 or 4 days of no failures, I'll do things one at a time, like plug in the printer, enable the RAM's XMP profile, etc. and see if I start getting failures or hopefully not, and I can attribute the success to the 1.3 bios.

    Since rolling back to the 1.30 BIOS, i haven't had any more issues. 5 days and something like 20 or 22 consecutive shutdown/sleep with no failures.

    Considering this one resolved. Thanks to all for the help.
    @me75006: for good measure I disabled the secondary ethernet NIC in the BIOS also, thanks for the tip.

    Great news. You might report that issue to your motherboard manufacturer to see if it may help them to fix the issue in a future BIOS version release.
