Hello. I have an some problem with my system/gpu/mobo I dont know which exactly.

At some point after having my system powered on, it often happens while the system is idle few days, my GTX 1080 becomes permanently throttled. The graphics clock is halved from a maximum of 1990-2000mhz (factory OC) to 1285mhz . When this occurs, it doesn't matter how much I load my card, be it games or other demanding applications, it does not ever go past the above caps. The only solution I have had up until now was to reboot the system .GPU-Z reports the "perfcap" reason as PWR

And I have found many topics with the same issue on internet, its one of them even with Gtx 970/980/1070/1080:


Just worried because I found topic about similiar issue here:


And reason was not stable oc. So maybe I have not stable factory OC? Also they had driver crashes from the link above, but me not, I have 0 driver crashes. And normally the event log will show the drive crash report which in my case it doesn't show.

Maybe this is different situation because my card must be idle few days and I dont have driver crash.

Any opinions ? Please help me, thank you.
