For as long as I can remember, I've always had a non working graphics driver called "Nvidia Geforce GT540m" in my device manager. I assumed it was a software fault or something and I didn't actually have the chip. I've always used the default intel hd graphics 3000 to do anything, which is dreadful btw!

Anyway, like the title says I found the chip inside when replacing the thermal paste (due to overheating problem) and since then I've tried everything I can think of to get it working.

My laptop model is SAMSUNG RF511, and yes. It is showing a yellow hazard box next to the driver in device manager.

I used driver sweeper in safe mode, then tried to install the driver via the NVIDIA website. The same yellow error came up. So I driver sweeped that, and installed from Samsung driver website. Same error.

Here are 2 links to a photo of the chip itself, and a screenshot of yellow warning error message.

If anybody knows what I could do here, I would love some suggestions! Thanks.

You cannot use the driver from NVidia. You have to use the unified driver supplied by the laptop manufacturer.

Why can't I use it?
This was supplied by the laptop manufacturer. It's in the laptop already?

The drivers you get from NVidia do not support the Optimus chip in laptops. The only drivers that do are the ones you download directly from the laptop manufacturer. They support both GPUs and the ability to switch between them. In fact, the NVidia drivers you download from the NVidia site do NOT support the mobile chipsets.

Agreed.
This is a common mistake people make. You need the proper software from the laptop support site.

Additionally, there is an OPTIMUS LIST you can add games or some programs to that will start using the NVidia GPU for those that aren't already on the list. Not sure if you can tell the program to temporarily show an NVidia logo so you can confirm you are running the NVidia GPU.
