Got a very strange problem with a clients laptop. She was running vista. The built in keyboard works intermitently. When it does work pressing the shift key acts the same as pressing delete. A left click of the mouse also deletes. I tried disabling the built in keyboard and touchpad but I get the same problem with usb keyboard and mouse.
I then did a clean install of Windows 7 and the I still have the same problem. Anyone got any ideas? This has my head wrecked!
