Hi ! I don't know if this will help. Sounds to me that you might have hardware problems. I do not have a HP computer at the moment.:smileywink:

PS All advisers here on the HP forum are always invited to reply on any issue where I'm trying to help a HP owner and member; old and new members. I do not have a EGO and I can take criticise pretty well.:smileywink:
Dokie!
