Our church bought a brand new HP 20-c013w Snow White All-in-One PC with 19.5" HD+ Display, Intel Celeron J3060 Processor, 4GB Memory, 500GB Hard Drive and Windows 10 Home from Walmart about 3 months ago. Was working wonderful...Sunday went in, and the keyboard was locked up. Finally got my password in by using the on screen keyboard, but could not use our Quick book program because the keyboard would not work. HELP! Jackie Ruby
