Attach your computer to your TV using an HDMI cable and I'm 99% sure that Skyrim will have controller compatibility for the 360 (and most likely the PS3 also) then you need to buy a 360 controller for PC or a PS3 controller for PC. You can find them by googling that. I use a discontinued product that plugs into my computer and allows me to use a regular 360 controller with my PC.
Edit: Actually, if you want the PS3 controller on the PC, go http://www.hardcoeware.net/how-to-playstation-3-controller-64-bit-windows-7-vista/ but the 360 controller for the PC is a different controller altogether and you have to buy it.
