Nice system.
1) Update your driver to 12.3 - download the full package. And is there any reason you are not using the March 2012 version of UDK?
2) Run memtest (Ver 4.2 USB stick is the one I use - but there might be a later version) I suspect your ram is not stable.
3) Your TV what is the native res of the set? HDMI from your graphic card needs to be set the same as the TV.
4) What is your LCD screen res? Issue with screens which are not native HDMI res.
5) If you are not using Bluetooth disable in BIOS, if you are using Bluetooth install the drivers.
6) Suspect that your sound drivers are installed just fine, but that you have not configured your playback nor your record default hardware as yet.
7) Window7 will show each and every wifi within range, I am talking the OS here. What ever software you have installed will act independently of that. Best thing is to do your OS install with a network cable connected and plug your stuff in, that way the OS automatically downloads any drivers that are needed. I too use a wifi dongle and that is the method I used as I found the software that came with the dongle bloated my system.
