Graphics Card Not Detected

[Ethan348]

Hey there,

I have installed 2 OS.. Windows 10 64-Bit and Windows 8 64-Bit Respectively..

Well.. The reason I installed windows 8 was that some of my games didn't run at all in Windows 10..

So after installing windows 8.. I installed latest driver for my GPU..

The installation was successful.. It did not show any error of incompatibility while installation..

I restarted my PC but Discovered that my GPU is not detected in Windows

The games.. Like GTA San Andreas run Awful in my Windows 8..

But.. I went back to my Windows 10.. Found that GTA V runs great (60 FPS Average)
I checked dxdiag.. Discovered that my GPU is Detected..

Why is my PC unable to Detect my GPU in Windows 8?
Some help.. Please

My Rig:-

CPU: i7-4790K @ 4.0 GHz
GPU: GTX 960 4GB MSI Armor OC Edition
RAM: 12 GB DDR3
OS: Windows 10 and Windows 8 (Both 64-Bit)

How did you revert to Windows 8? A clean install or a factory reset? Factory resets can cause more problems than they fix.

Ok, so you're dual booting Windows 8.1 and 10?
Check in Windows 8 if the GPU shows in Device Manager at least.

Try putting your card in a different PCI-E slot or reseating in the existing slot if you only have one available.
Reboot your computer, go into the Bios and make sure primary video is set to your add on card not built in, save and reboot.

It works!! Man!!

After rebooting my PC.. I saw the screen flashing for a while.. Now.. Directx Diagnostic Tool shows that my Card is installed..

You made my day
