Well Joan , I have tapped and blown and loads of bits came out so far so good I think you may have cracked it ! The trouble is my son gave me this lap top and he has psoriosis very badly and I have it a bit too and I think possibly that doesn't help with all the skin shedding. Thanks a lot ,whilst typing this it seems to be ok , whoops having said that it did it again , but I think I will get one of those air jet canister thingies and see if that cleans it right out because its a lot better

ps I have just thought I use the delete key a lot and inserts just above it so I bet I have pressed that by mistake !
