I have a new Toshiba satellite. It is a P55W-C 8GB Ram, intel core i7, 2.4ghz, 64 bit operating system. No idea what any of that is but was told this should be a fast computer. It isn't. It is very slow loading web pages and it lags when I am typing, not only on the internet but just a simple word document typing is very slow. It literally stops and I have to wait 20-25 seconds then begin typing from where ever it stopped at. When typing does stop there is usually a blue spinning circle. Please help. This computer is basically useless to me as it is
