Unstable with arc a770 le 16Gb

[nVidia]

Hello,

I bought a new Intel a770 card and was very happy before my PC started reboot unexpectedly (it seems like a power off for 0.5 sec). It happens every 1-2 hours in an idle state. I newer got it in games. I suppose it something with a PCI-E power in an idle state (when I do nothing with my PC)

I did everything:

* I did clean installation with DDU in a Safe Mode

* I changed Beta and WHQL drivers

* My BIOS is the last version

* removing and put back the card and 8/6 pin to the motherboard

* make BIOS default (except Intel LAN disabled)

* It even can happened without installed Intel driver !

If someone interested I found the problem. I switched off all sleep, hibernation and turn off the monitor after 10 min in the Power management options.
Everything is stable now
