last week my moms HP pavilion laptop went funky. It became extremely slow to the point i had to go into safe mode to retrieve her files. At the same time this happened, certain keys on the keyboard stopped working. I formatted the PC and upgraded her to an SSD. Computer works great now, but the keys are still not working. I tried everything i could find (uninstalling/installing drivers, toggling settings etc.) with no resolve. I temporarily got them to work again by holding the non working key down for a solid minute. It worked for a short time then stopped again. I'm beginning to think its hardware related and it needs a new keyboard, but its too much of a coincidence that the computer went haywire at the same time. Any ideas?
