I was trying to diagnose my Xbox 360 wireless adapter to play some games on Steam yesterday. The adapter light would light up but the controller wouldn't connect. I had seen this problem before and all I did was go into the device manager where I can view the wireless adapter that was plugged in. The device manager showed it as an unknown device, so I right clicked went to "properties", then "driver" tab, then "update driver", then "browse my computer for driver software", then "let me pick from a list of device drivers on my computer", and then scrolled down to the latest driver I had installed. I was then prompted by a statement along the lines of "This driver does not match the OS you have and may cause issues with your computer if you continue to install". But I swore this was the driver that worked last time so I continued to install. Now, my disk is bogged down with 100% use and I'm assuming there is a corruption caused by the driver. I tried cleaning my computer, reverting back to a couple of previous versions of my system, and running check disk and nothing has worked so far. Maybe I have gone about the processes wrong or there is another way to work around this. If anyone has any advice, please let me know.
