PCGameGuy: Just a thought, but have you tried putting the Logitech dongle in the front USB ports with the least obstructed view? I know trying to get signal past the monstrosity I call an entertainment center can be a bear, so much that I bought a male-to-female USB cable and put the dongle on it towards the front of the TV stand to get it out of the RF nightmare. :)
Yeah, it's plugged into the front USB port of the computer, and there is no obstruction in between. It is sort of in and out, not consistant enough to count on. But if there is an obstruction (like somone standing) between the couch and computer, I get ZERO results. Mouse doesn't budge. But even when unobstructed, it sort of half way moves, or something I'm having a hard time explaining.
I'll slide the mouse left to right for example, and the mouse cursor will move left to right, but jumpy, and it stops and starts and is really hard to ever get to point at what I want. But when I move closer, it's fine. Didn't anticpate that at all because the couch can't be more than 10 to 12 feet away from the where the computer sits. Have been wondering whether or not to try a different brand or model, but would hate to spend that money and get the same result.
ADDED IN EDIT: I just found and ordered what I needed to hook up those final two fans. It's cool because this case has 3 front fans that are colored red (and two rear ones colored red with two on top not colored) and right now only two of the three front fans are running and you can tell there should be another one and so it looks weird. It will really look cool once I get all of them hooked up.
