All the little holes that plug into the MoBo have those silver things inside except one. It is empty. Do you think this is enough to stop my new setup from booting?

Oh dang. When I power up my pc, the back fan moves a little bit, the CPU led turns red for half a second, and I get no image on my monitor. The only way I can reset it is buy actually powering off the power supply.

Oh yes I have those on there. I re-checked the MoBo and it doesn't seem to be tightly secured. It moves down a little bit if I push on it lightly. Is this a big problem?
