nvidia Graphic card not detected in device manager

[Na28]

Hi,

No, I can not change anything. I do have an error 45. ''Currently, this hardware device is not connected to the computer. (Code 45)'' when I click on it in the device manager.

Sorry, I was able to change something in Bios. I think it sayd something about programs being able to run at the same time. 

The the graphics card was visible in device manager but I got the error: ''

Windows has stopped this device because it has reported problems(Code 43)''

I was able to install the driver though! But now the error changed to: ''This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

The specified request is not a valid operation for the target device.'' 

I did a clean install with the driver I downloaded from HP. This seam to work. It now is working properly! But....

UPDATE: It disapeared from my device manager again! It is listed under hidden devices again and giving me the error  ''Currently, this hardware device is not connected to the computer. (Code 45)'' again!

Does it maybe mean that the hardware is loose or something and it does not connect properly. Just sometimes? It is so weird... Can you help me?

Hi:

Unfortunately, I wouldn't be able to help you with the problem since I am not a PC repair tech by trade or training.

It appears to me that it is a hardware issue of some kind which you may have to replace the motherboard to fix.

The GPU is soldered to the motherboard, so if it came loose, there is an issue with the soldering attachment of the GPU to the motherboard.
