Question Pc is very slow if the disk is 10% fragmented or more.

Well this isn't really a issue as i can easily defrag the hd but still seems a bit weird. As the pc fragments pretty quickly (could be cause i delete - replace and move game files quit a lot) and when i defragd it today it was at 13%, and when it reached that % (could have already been a issue at a different %) everything was VERYYYY slow internet browsing(first thought it was a wifi issue but no it was not), game loading times (even caused stuttering or light freezes,) and general pc usage, the pc ran as a old pentium 4 pc with intel gma graphics but it's not. So why is this a issue?

Spec is == I3-530 - GT 330 GDDR3 768mb - 4gb ram ddr3 - 1tb hdd (for some reason only 931 gb usable? don't know where the rest 69 gigs are)

Windows 7 64bit PRO /Just in case, yes it is activated.
