Disabling the wireless card is easy:P just unplug the usb stick (my wireless card is a usb stick) it's a shame it's that piece of hardware, because it's my only access to the internet atm. (my parent's won't allow to make a cable in the house)
I will run the memtest on ultimate boot cd and post the result. (i believe the one you mentioned is on there)
also i will run a harddrive check,, ill post the results when i have them.
