I have a Sony vaio All-in-one touchscreen that had windows 7 installed. I originally had done an "upgrade" to windows 8 and the touchscreen worked fine. My HDD was starting to fail though so I just bought a full version of windows 8 and installed it on a new SSD.
Ever since this the only way I can get the touchscreen to work is by going into device manager and uninstalling "Intel(R) HD Graphics" and then restarting the computer. I have to do this every time I restart the PC or the touchscreen doesn't work.
Any ideas on an easier workaround?
