Question about warranty for my PC.?

OK so I have had my Advent desktop for just over 7 months. While moving it last night the wireless antenna from my wireless card got caught on my desk and ripped right out. The wireless card doesn't work any more due to this. Can I claim on my warranty for this or not? I really need the internet and don't particularly want to go out and spend $50-$70 on a wireless adaptor. Please help me out here!!!
