I was finally constructing the case to my portable, and man does it look cool

Anyways I've been having trouble with the expansion port, sometimes it works, sometimes it doesn't, but I've had no problems pretty much. When I was putting my case together, everything is soo tight that I had to bend the expansion port a tiny little bit. anyways it stopped working, so I unplugged it put the normal one in and turned it on. It worked, then I tried putting it in the case again, it stopped working. Now I can't even get it to work at all!
I know the screen works (indicator lights) All wires are hot glued so nothing came loose and I'm sure the power works ( LED comes on )
Did my N64 fry, or did the expansion port break?
Also some other thing that may have broken it. I ground the N64's heatsink, away from the N64, but I think there was some metal dust on it. Could this short it out?
Do you guys think I should buy a new N64? Please help....
