Earlier today, i was unplugging the network cable from my network card when i heard something fall inside my case. I turned off my computer and opened it up to see what it was and oddly enough, my network card came loose and fell out of its pci slot while the computer was running. Funny thing is, my computer didn't lock up and everything was running like normal when i put it back in and turned on my computer again. I figured at least the nic or the pci slot would've got fried doing such a thing. Guess i'm lucky.
