    Windows 8.1 - Rebooting when system is in idle for a time

    Hi all

    I'm a bit desperate, cause when i leave my system in idle for an hour or two, it reboots without any BSOD, or any error messages. My rig is 5 year-old, and always worked perfectly with Windows 7, without any strange issues.

    When i'm working, Win 8.1 works absolutely perfect for long long hours.. rendering video, playing games etc.. i never found a BSOD or random reboot.

    I did the following to try to solve this problem, without success:

    - Changing my PSU.
    - Changing the Win 8 energy plan to Maximum Performance (hard disks never turn off)
    - Memtest for 16+ hours, without any error.

    My guess is there are some Windows 8.1 feature that doesn't fit well with my mobo, but i can't find it.

    I have also the same version of Win 8.1 installed in another older rig, and works 100% perfect during days (working and idle).

    This is my problematic rig:

    Gigabyte P55-A UD6, BIOS F12c Beta (the last available from Gigabyte)
    G-Skill Ripjaws DDR3 2000 8Gb (2x4Gb)
    Intel Core i7 860 Lynnfield
    Sapphire Radeon HD 7950 3GB GDDR5
    Corsair Force 3 180 Gb (firmware updated)
    Creative X-Fi Titanium

    Any ideas would be really appreciated.

    Thanks in advance.

    For those with a similar problem.. i think i finally found a solution!!

    I disabled all the wake-up on lan/modem features in the BIOS, and voila!.. my pc in idle for 4+ hours without rebooting, at least for now

Defrag disabled, but still tries to run when system idle
Despite having disabled the defrag it still tries to 'optimize the drive' when the system is idle. Is there any way to override this? It's only started doing this again after I installed the huge rollup update earlier this week.
