GPU not working?

[GustavEngvall]

So I just finished building my pic and installing necessary programs. I start up a game and it's veeeery laggy. I think "that's weird" cause I have a MSI GeForce GTX 960 gaming edition. I download MSI afterburner to check if the GPU is there or not. It says nothing about the GPU but only the cpu. The MSI logo light on the GPU is lit. The fans on the GPU are on the first 10 minutes the pc is on then they turn off.

How do I fix this/ What did do wrong while building?

(I have a MSI GeForce GTX 960 Gaming Edition and a Z97S Sli Krait Edition motherboard)

Hi,

Please do try these troubleshooting steps that I suggested to others who had the same problem.

- Go to Device Manager and uninstall the Nvidia GTX driver.
- Check Programs and Features and uninstall anything related to Nvidia.
- Once done, download and install the latest graphics driver.
- Here's the link: http://www.nvidia.com/Download/index.aspx
- Reboot your PC once the latest driver has been installed.
- After the reboot make sure to set Nvidia as the default card.
- Here's how to set it.
