Hello,
New user, thank you for the support/product (CCleaner), I think its great!! I make my 15/13 Y/O daughter and son respectively run it on both computers (all accounts) weekly, and I can see a noticable difference afterward!! The thing is, since I first started using the 4600 it has always been slow to respond/download/upload/ with just about any application. Also, since I first used it, the screen flickers. Now I read in another mag. recently that the 4600's were crap and I can believe that statement!! Actually it was a Xmas gift for my son and when I helped him set it up on Xmas day and we wound up having to return it because of the power!! Had I known then what I know now...... Anyway, do the symptoms point in any direction, and if it is power could buying and installing a new power system help? Thank you for reading/responding.
