I was streaming some anime then out of nowhere my computer blue screens, it restarts fine, windows runs fine but a few letters on my keyboard stopped working. Windows 7 is OS dell inspiron n5010 is my laptop. P,o,i,u,w,e,r all do not work on my keyboard there might be a couple more that i have not noticed. no i don't remember the error sorry it was too fast. I scanned using advanced system care 5. It fixed a lot of bugs among other things but i don't think it did anything to help my situation.
