hello, i bought the above laptop over a year ago, whilst it was in warranty i spoke to one of your agents online in the chat room, i was having problems with the computer speed, he helped me to speed it up by downloading some software and installing it, it lasted only a matter of days and then slowed down again, this is the third time i have emailed you about this problem, but as yet i have received no reply, the computer is so slow, i have tried resetting it to factory setting three times, it does make it faster for a few days and then slows down, i have also tried the usual things, like deleting browsing history, it is now so slow that i have virtually stopped using it and use my ipad most of the time, when i try getting websites up, i sometimes wait up to 15 minutes for it to load, this happens on all websites, i am at a loss of what to do, would somebody please reply . regards. bob morgan.
