I have a problem.
In random external locations image disappears on the monitor and video card fans start rotate at maximum speed. Nothing helps except rebooting pc. This problem even in low graphic settings and disabled OneTweak. This problem only in Enderal, thats why I write here.
GPU temperature is normal (40-50°С) and backplate to touch cold.
My specs: 4670k, gtx1070ti, 16gb ram
In launcher I choose 4 cores and 10gb memory

welcome to the forum

just to let you know:
that's a new one.
(nice ?)

it's really only Enderal
otherwise I'd say it's a hardware issue, but..

you could take a look into Windows' event log (I can only give you german translations - actual words may be different):
(right after the next shutdown)
- search via taskbar for "event viewer"
- in that screen, open "custom views" and then something like "administrative events"
- is there anything of interest in that list on the right, right before you rebootet?

Which anti-virus program did you install?
Disable it temporarily.
Just a try...

hello, thanks for answer.
Yes, problem only in Enderal. I tested my video card in furmark for half-hour, also played other games in gpu max performance power management mode.
In Eventlog nothing interest except unexpected reboot.
I don't use anti-virus

Did you play Skyrim on this system before, maybe with mods?
Were there similar problems?

Do you use an enb, ENBoost or similar tool for Enderal?

Do you play other HighEndGames on Steam without any problems?

Yes, I am playing new highend games. For example AC Origins runs smooth.
I don't ever played Original Skyrim before, but I played Skyrim SE with tons of mods and no troubles with it.
In Enderal I don't use enb. Of the mods I've installed XPMSE, FNIS and Realisic Ragdolls and Force

That sounds strange, do you use overclocked Hardware (CPU/GPU)?

My CPU overclocked to 4 GHz, but it works stable, no throttling or overheat in games and stress-test

I don't know anything about overclocking,
but apparantly it's the game's engine that might have an issue with it

there's no harm in trying without :/

Try to use only 2 cores and disable experimental multithreading (if it is activated).

edit:

But I think that's a hardware problem. Maybe caused by your overclocking. Or a broken hardware.
There is no known Skyrim engine error causing these problems.
Maybe you are reducing the overclocking.
