hp stream notebook pc 11
Microsoft Windows 10 (64-bit)

Hi there, 

I have  a HP Stream notebook pc11 the touchpad & cursor have stopped working after a clean & reboot of windows 10 from a usb stick. The device manager shows the PCI encryption/decryption controller has a yellow exclamation mark next to it, so I downloaded the recommended driver from HP website; Synaptics Touchpad driver filename SP71867.exe.              I installed the driver from download & restarted the laptop, 5 times but still no joy.  I've tried connecting a wired mouse but that hasn't worked either. Any ideas?
