Hi people, My bro build his own fast computer... He has an Intel Core 2 Quad at 2.83GHz and he overclocked it to 3.59GHz and has 4GB of RAM... When i open some stuff like installing or opening something up(CS5 or some games-Steam-), it's taking forever(the loading) and the CPU usage isn't even at 100%(only 20-50% CPU usage and RAM usage at 1.50-2GB)... How is it so slow or taking forever and how do i solve it? Does it has too much stuff or the HDD is slow(7200 RPM) my bro has 2TB(2 HDD) and the OS HDD is almost full with 391GB space(Has movies and software that my family needs)... Why is the computer load time is so long or so slow even with OC? Sometime i think it's the HDD not spinning... How do i know it's spinning?
