Starting my computer from standby i have discovered that my keyboard is not working properly. i am now only able to type whilst holding down my shift key other wise it comes out like this: ican only ty hilst hlding don my shift ky. it appears that maybe some of my keys are sticking as some do work sometimes but generally i can type when holding down the shift key. i have reinstalled the drivers and nothing has changed. even my delete keys etc only work with the shift key! i have restarted many times to no avail. i have a packardbell r650 which runs a microsoft natural ps/2 keyboard.
