Well when I finally got the Shuttle back I had a look and not just one pin was bent but all of them!!! I must have screwed the heatsink on too much. So I decided to try and straiten them all out but it didn't work. Yeh I'm gutted but I should have been a lot more careful now I'm gonna have to fork out another £100 for a new case, mobo and psu to justify all the other working components so let this be a lesson:
DON'T SCREW A HEATSINK ON TOO TIGHT!!!
DON'T SCREW A HEATSINK ON TOO TIGHT!!!
