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.

Greetings

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 :)
