Graphics card error message

[Anonymous]

I recently installed a 2G nvidia GTX 750 ti to my relatively old computer in order to run Fusion 360. It has been fine, managing to process quite complicated meshes.

However, I have just started getting an error message on Fusion boot up that says: 'The software renderer is being used; it could be due to the graphics card not being powerful enough or its driver is not installed'.

If I dismiss this error Fusion opens but it cannot be used as it cannot process he graphics.

I have updated the drivers.

In PC properties under Device Functions I get a message that says: Windows cannot initialise driver for this (Code 37).

Any thoughts anyone?

Thank you

Hi @Anonymous

The error is in windows? If so you may need to uninstall the older drivers and reinstall during Nvidia's reinstall procedure.

Thank you for that Ryan.

Working out where the problem lays is the issue!

I have tried reinstalling the drivers via the Nvidia site. During this process i get a message saying the system is incompatible with the new driver and that it cannot 'find the hardware'. I have tried this several times with both older and latest driver updates. On one occasion it DID upload a driver, but Fusion is still only recognising the 128mb that I presume is the basic motherboard graphics capacity, and not the 2Gb of the Nvidia.

From the fact that it loaded a new drivers ONCE, I can assume that the GTX 750 ti is still supported, and this isn't the issue?

If I re-seat the card Windows says it is looking for a driver for the card when I boot-up. It says it has done this, but in Device Manager I get a Code 37 'Windows cannot initialise the driver for this device'.

The dxdiag tells me there isn't a problem with the card although can't specify the manufacturer etc.

Does this all point to a specific issue that I can address, as not being a tech expert, I am struggling to isolate the problem.

Thank you once again.

Well you have all the info you need

1 the slot in which the graphic sit is K for not working

2 the card is not compatible with your mother board and is not supported by the south bridge 

3 the card is not supported by your OS

there is nothing you can do within fusion 360 to sort this out its purely a pc problem 

one thought have you tried the card in a different slot or another pc 

last resort get a new pc 😳
