As a test I would remove your Airplus card to see if that resolves the error issue.

Network cards are mentioned in both those links I listed RE: Parity error:

Hardware Malfunction Results in System Error Message

"NMI: Parity Check/Memory Parity Error"

If it appears to be the issue perhaps reloading the file & or drivers may help:

Once I had to reinstall everything, and so I had to remove the card, when I shut down my computer without the card, it shut down without blue screen, so I know..
I reinstalled it with the correct drivers, I downed from their site.. so I don't think there's much to do about it :? I have no idea WHY it's doing this, appearently my computer doesnt 'like' that card or something :s anyway, big thanks for your help! I don't think there's much else to do about it exepct buying another card, but that's not an option for me right now....
