I have this wireless card, and worked fine in a now doa system, and its been sitting on the shelf for a while. I went to put it in my kids system today, and when i put it in, the system won't boot up, hell it wont even hit the post, but i take it back out and the system works flawlessly. do I have a dead wifi card now? system is a Asrockk7vm3 mb and Athlon xp- 2100+ and works great until I put this card in as stated above.
