HP TouchSmart 600-1170a all in one desktop PC responds to touch in TouchSmart mode but stopped responding in ordinary mode about last February.
Windows 7 Home Premium Service Pack 1 with all updates, 64bit
File of System Information attached.
Pegatron Motherboard E66 Chipset
Have checked Pen and Touch in Control Panel & OK. Removed all ticks, rebooted and readded ticks, no change.
Have performed all the suggestions on HP site ie clean screen, especially top left and right corners, power down and unplug everything etc.
After second clean of corners ordinary mode worked for about a minute but can't get it to do it again.
Any suggestions, please. I imagine a clean start with a complete reinstall may solve the problem but I shudder at the thought.
Thanks for consideration.
