Graphics Card dead?

[FeedMe]

Hey there  

Hope you all have a nice day / weekend

 

If have some problem with my system at the moment: 

 

The system don't detect the graphics card - not in Windows - not in the BIOS.

 

So I uninstalled the card to bring it to the shop - it's only 2 months old, so I want a new one.

 

Last night I just tried the card again - a fortune cookie told me that my problems will disappear  

And the card worked - I played - I tried benchmarks - everything was fine .

 

Today, another day - I started the PC - no card detected - the same problem again  

I tried a other pcie slot - without other cards (wifi) or USB ... No reaction.

 

I think the card is dead...Or have I something overlooked  

 

System:

 

Asus Maximus IX Hero (last bios)

Intel i7 7700k

G.Skill RGB 16GB (2x8 GB) 3200

Asus Strix 1080 Ti (maybe dead) 

EVGA Supernova G2 750 Watt

Sandisk SSD Plus 240 GB

Seagate Baracuda 1 TB HDD

Did you install the drivers?

The PC works fine for about 2 1/2 months ... So yeah, every driver is installed and up-to-date
