I have a card Decklink Extreme PCIe
ASUS P5B Deluxe Wifi-AP Edition.
Intel Core 2 Duo E8400 3.00GHz.
Kingston DDR2 HYPERX 2GB x2.
NVIDIA GeForce 9600 GT DDR2 1GB.
HDD Western Digital Black Caviar 500GB
That wi-fi card may have already installed tons of unwanted play- maedia- only software and could turn off software installs midstream in order to wobble about the internet looking for different drivers. Check for these types of "viruses" by doing a fresh install on a borrowed hard drive, and the wireless unit either turned off or well- grounded in aluminum foil. Trying to turn a computer into a production computer while it`s on the internet can cause problems.
