The information about your system would be in Control Panel, System.
I'm on a Vista system right now. I asked about Firefox because, in another thread in this forum, people using Win 7 were reporting the same message, when using Firefox. I use IE, Firefox and Opera on this system. I also have a MSI GTX 560 TI on this system. I was getting the same error message if I had Firefox running, when using another browser. Last week, I didn't open Firefox at all and never received the message. I didn't check it on my Win 7 system but I have the graphics card disabled for a specific reason. So, what it comes down to is that there may not be a problem with your graphics card. You can try using a different browser for a few days just to see what happens. The other option you have, that I don't (on this system because Vista is no longer supported) is to make sure you have the latest version of Firefox. I'm stuck at v52.9.
In regards to the driver, if you want hardware acceleration to be available, you need to use that driver or earlier. NVIDIA disabled the use of CUDA for hardware acceleration in the later drivers for cards earlier than Geforce 600.
The other issue is that computer vendors sometimes modify discrete graphics cards, like yours, that they install in their laptops and a person can't use a later driver than the one they provide. If that's the case for you, when you tried to install a later driver, it would say it's not applicable.
For information, if your system is not a notebook and it's 64 bit, you can download the latest driver here-
