I have a PH Slim line that is 5 years old with 3gb it still has the same hard drive and I just sign up for guitar tricks 4 days ago and I have been on the site a lot and I am not having any problem so for I had my HP debugged at Staples Office Supplies I bought a 1 year contract with Staples and believe me it is worth. Or it could be your flash player needs updating. I am not a computer expert but I thought I would try to help. Good luck
