A driver for windows 10 does not exist.
You updated your laptop to windows 10, and you can go back to your previous OS (windows 7, 8, or 8x).
You can also try the latest Microsoft compatibility/generic driver here:
To confirm your situation, look here for HD 3000:
It is simply not supported, and will not have a new driver.
It also means your processor is not supported.
So, there is no solution here. Not supported means not supported.
Now, your laptop turning off while being used could indicate an entirely different situation. You should contact the manufacturer for support with this problem. Suggestions may be to replace your battery, power supply, etc. It could also be overheating, the memory may be bad, etc.
