i have a dell dimension 4600 desktop .. presently my mothers laptop is connected to the internet via wireless. I tried to connect the 4600 wireless too but i keep getting the blue screen of death and have no idea why. It works fine when directly connected to the netgear router but when i put the  usb wireless 2.0 adapter i get the connected until i restart it... then the blue screen of death... any ideas what i should do to correct this? i would really like it to work so that i can move it to a more convenient place for my parents who are elderly and have a tough time climbing stairs.
