My motherboard intel(R)82559 won't work

I had recently tried to add more harddrives into my system, (Never try this on your PC) I went to add Add Hardware and out of no reason I decided to to press on system devices, I just incase it was missing some devices. This thing popped after a moment, it read something like want to restart?
and then when it turned off, like three times the computer shut itself without any attempt from me, but after awhile I almost took the AC power off cause I was afriad it would crush like that but after moment this block screan showed up and Taaa-daa!
I was relieved but later...Getting back on my computer was a sad outcome. Because now it has his message from my local network connection saying, there's network cable unplugged?!
I can't reintall my motherboard because everytime I try it says, this device cannot start, code 10!
PlEASE GIVE ME SOME ADVICE TO FIX THIS STUPID PROBLEM!
ALSO MY NETWORK CONNECTION CONNECTION INTEL WON'T ALSO WORK and MY SERIAL CABLE IrDA protocal won't start because the sytem recieved a problem with it from the continues shut down!
AGAIN I NEED TO GET BACK ON THE COMPUTER AND I DON'T WANT TO SPEND SOME MONEY ON SOME GUY THAT WOULD ONLY FIX THINGS I may be able to fix!
SO PLEASE HELP ME!!!!!!!!!!!!!!!!!!!1
