What is the reason for my trouble??

I have just got a new case-HAF-X and i replaced all the stuff into my new case.When i started it, after it said "DETECTING THE RAM SIZE", it restarted over and over again. Then i removed all the rams and put it back, it started normally.But as soon as i restarted the windows manually, it again came out with the same "DETECTING THE RAM SIZE" problem. To try out if the problem was about the rams, i tested them one by one, and IT WAS OKAY. But when i used the third slot out of (1,3,5 white slots) ,it gave me the same restart problem while saying DETECTING RAM SIZE. Later i avoided using third slot, it was okay again. I used the pc a while like that. After some time, i tried the 1,3,5 slots with no problem saying Detecting Ram Size,yet it said that usable ram size was 4gbs that was what included in BIOS infos. WHen i right clicked and looked at the information about pc, it said that there were 6gbs ram but the usable is 4gbs. In CPU-Z and Easy Tune, ram size is confirmed as 6gbs.

I had no problems in my previous case but is there any possibility that something was done wrong while i removed all the stuff and put into my new case, like bending the cpu pin?

 Going off the CPU image.......you definitely have an issue (Possible bent pin/s) in the lower 7 o'clock quadrant ..... Can you get access to a 20/40X powered microscope and a pin ?  this would be my first step in attempting a fault find mission, you just have to see and fix one thing at a time till you find the gremlin!

 Update......... no enhancement, just a crop in photo-shop of the area you need to look at!.......You'll notice a bent pin, I've included a second image of what it should look like after you repair it......Again this is a possible cause.

Hi

Actually there are several bent pins there that I can see even thiugh the photo isn't very good. It isn't hard to repair them if you have some needle nosed tweezers and a good magnifying glass. You will also need a steady hand with plenty of good lighting.
