Airport card freezing up Mac

Last week I had a problem with my graphics card that "burned". I got my Mac back a couple of days ago and yesterday I decided to clean it up on the inside, something I've never done in 6 years.

I just used a clean cloth, a brush and a can of air. I tried to be as careful as possible. When everything was set and done I booted the Mac and everything ws fine and dandy. A few hours later, I booted the Mac again and it froze when booting in Windows 7 (Bootcamp). I restarted and the same problem appeared.

I then booted in OSX and turned on Wi-Fi (I use a direct cable for internet) and the OSX froze too. I then booted Windows 7 in Safe Mode, disabled the wireless card and so far it's been working.

How can I fix this? What could I have done wrong? I don't really use wireless in my MacPro, but I don't want freezings anymore.

Was this my problem because of the cleaning? Was it possible that this was caused with the swapping of the graphics card?

Weird stuff... :confused:

Thank you!

P.S. - I used Lorenz Bell Spray Duster. Personally I think it sucks because it doesn't seem to have a lot of "power", plus it created some wet zones, so I just tried to used it on the fans.

Pure guesses…


Spray residue across/in the wireless card -> motherboard slot?

Spray residue shorting the wifi antenna plugs?

Your flambé gpu deposited conductive materials where they should not be?

Your flambé gpu took out more than you first thought?
