My HP upper keys dont work except for 56 - HP Computers & Internet

OK, it sounds like your keyboard has been hijacked by an infection. If it works long enough for you to login then it works, but stops after windows loads because the virus also loads.

Try going into Safe Mode and see if the keyboard works. Turn off your computer, then hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see Safe Mode. Select Safe Mode and let it boot up. Safe Mode will look different to you because the screen will be darker and the icons bigger, this is normal. Once it boots to your desktop, try using the keyboard. Open up something like Notepad or Wordpad and hit every key to see if they work. If they work, you surely have a virus infection. Most viruses can't function in safe mode because they need a internet connection and a normal startup. if the keyboard works lets get the lil ******.

Turn off you computer again and turn it back on and immediately start hitting the F8 key repeatedly until you see Safe Mode. This time scroll down until you see SAFE MODE WITH NETWORKING.
