Latest drivers and bios for legacy laptop

Hi there. I purchased a Novatech nSpire 2760 - Black Edition - 15.6" Intel i7 2760 Mobile Processor - 8GB DDR3 Memory - 500GB Hybrid SSD Hard Drive - DVD Writer - NVIDIA GT 555M Graphics
[ NNB-904 a number of years back. I’m trying to update it and hopefully run win 10 on it.
Failing that I will have to stick with win 7. Can you tell me where I can get the latest drivers and bios for it. The current bios is 208 which I think needs updating.

When I install win 10 as is, the WiFi doesn’t work and even with a separate dongle the system ultimately crashes.

Your assistance would be gratefully received?

Many thanks D
