Sleep option suddenly not available (grey).

[Showiz]

Hey,

So basically when i woke up my PC up it said "Resuming windows' instead of the normal "choose user" menu maybe because something crashed idk.

Then it said "driver was successfully installed" and i don't know which driver it updated because i did not plug anything new and my windows updates are disabled.
Since then sleep option is gone in the menu and in "power options" i can't re-enable it in "changed advanced power settings" because it's gone.

Hibernation appeared on the shut down menu and i disabled it through the CMD.

I checked if any device is preventing the PC to sleep and didn't find any strange device, i reinstalled Nvidia drivers, didn't help.
And i've noticed that in "Device manager" under "display adapters" it shows my GPU and it shows "Standard VGA Graphics adapter" with a warning, tried to update it and reinstall it and sleep is still not available.
And a LZMA.exe showed up when i tried to shut down the PC once....

How can i fix this stupid problem?

Thanks in advance!
