OK I see the Atheros driver. The only thing that I have installed on the system is an Actiontech Wireless N USB Network Adapter.
You need to install the chipset driver followed by all other drivers.OK, thought that I did originally, as I have the file on the computer. Did it again just in CASE when you first mentioned it. Now just have to sit and wait lol. It will BSOD with in 10-15 mins if it is going to Ill be back to let ya know.If the problem continues, the only solution I SAW on the web was to discontinue wireless access and switch to an ethernet connection. If that's not an option you might want to contact Qwest.Yeah saw the same thing So far so good though. I thank you for your help.yepLaaaame got the BSOD again. Yeah, based on the other posts I saw with a Google search I thought you might.Wonder what it is. I wouldn't think reinstalling Windows would do anything. Ima pull the USB adapter and see if I BLUE screen with it out. If it doesn't then I take the adapter outside and smash it with a hammer.As I said above, it might be worthwhile to contact Qwest.Curiously, why Qwest? You mean Atheros?Sorry. Yes, Atheros
