Start | Run | msconfig <Enter>

BUT....be VEERRRY careful what you turn off.

Also, you might consider downloading Malwarebytes, Spybot Search & Destroy and AdAware. These are three free and very powerful tools that I use A LOT when working on people's machines.

Also, if you don't have Symantec (aka Norton) or McAfee, download AVG and install it. It's free also.

All of these are gonna suck to download if you can't get your aircard working. Fair warning.

Let me know if you need more help.
