Computer running slowly

[Bawat]

For some strange reason my computer is running much slower than it used to.
CPU usage is almost consistently at 2%, 21% of 16Gb ram in use. 18Gb of space left on the Raid 0 SSDs and yet doing things on the computer is taking too long!

Drive is only 7% fragmented and AVAST doesn't detect any problems.

Running this

#include <iostream>

void main(){
	std::cout << "This is a test";
	std::cin.get();
}

Takes about 2 minuets to get an output! What is going on?

Ohhh that could possibly be it... I saw it was 50% fragmented once and decided to fix that... Only the past few days really, computer starts off fine but then opening anything and doing anything progressively gets slower until a restart. I can't think of anything off the top of my head, I've only been playing games and recording them recently.

[Edit] I just realized that that can't be the cause since the computer being slow was what gave me the idea of fragmenting in the first place

I am using Windows 7 Home Premium and have my OS installed on two "Samsung 830 Series 64GB Solid State Drive SATA 6Gb/s 256MB 2.5 inch".

I have just bought two "Samsung SSD 840 Series Basic 2.5" - 120 GB (MZ-7TD120BW) " if I can use that to compare stuff on this computer
