Hi there
My PC was working all fine. Until the electrecity has suddenly disconnected for seconds then came back. Once I turn On the PC back it works fine, the fans and LEDs of Case were working all as normal.

However, the screen was showing a black screen with NO SIGNAL message.
I tried to plug in and out the DP port from both the GPU and screen with no benefit .

The LED logo of GPU is working and fans of the GPU is still spinning normally as well!
I tried to plug the screen to the motherboard insted of GPU and it works fine. I tried to open device manager and I could not see my GPU, I tried to open Nvidia Geforce app as well and it says no NIVIDA card is found!

I tried to plug in and out the GPU with no benifit.
Any help?
