im running windows XP and have a small prob, firstly when i try a do a system restore the page opens but is blank this is the same with emails when i open an email nothing.

When im on passionford and want to add a smiley nothing, when i do a bit of shopping i can get as far as checkout and then nothing

also i can not watch any video`s of you tube and the like because it says i need to down load the latest version of flash player, when i click to down load this nothing happens, only 2 weeks ago my comp was fine and would do all of the above no problem

any suggestions computer guru`s please
