Can you boot into safe mode? If you can then uninstall the gpu driver then boot normal and download/install it.
thanks for your help, I wasn't sure which one to uninstall first.
I think you're referring to the Intel GPU driver that Windows Update was trying to install?
Something strange just happened though too. I was trying Startup Repair and it didn't find anything wrong. So it shut down the PC and I started it up and now it's working fine...
