Need a new motherboard

[Hammered]

I was changing my system fan, and when i turned on my comupter the network controller dissapeared. I tried everything you could think of to get it back. So i guess i ruined something on the board that causes it to dissapear.So i guess i need a new motherboard now. Here are some specs.
120gb Samsung evo SSD
500gb HHD
Pny geforce 650 2gb
AMD-6800k 4.1ghz quadcore fm2/fm2+
4sticks equaling 12gb or ram PNY


Any suggestions on a new motherboard, i have a 200$ budget and i also need a new case because my current one it a piece of shit.
I use this computer for gaming, like bf4 and cod ghost
And if you have suggestions on other parts let me know

if you want a direct drop in replacement then buy the same exact motherboard, no need to reinstall windows or anything. Ive done this with two systems that the board has died, swap everything to the new board and turn it on. If your wanting something new you will need to reinstall windows and buy a new copy of windows unless your have a retail version.
