Problems with wireless

Hello, I am using a custom-build desktop around 6/7 months old, it uses windows 7 64-bit. I am having a few troubles with my desktop, I had to replace my wireless card a few days ago ( it broke ) and swapped it for a new one. This new one actually works fine, on other computers. On my gaming desktop it does but I could for example, only surf the web and chat on msn. Anyhow whenever I run some big program like TF2 or other games, I could list a few but that is not really the point. My wireless crashes, and I have to reboot the wireless card in order to make it work again. I tried to re-install the driver and such. Still though I am having the same trouble.

(In case if it is not clear the problem is coming from my desktop)

I just wondered if anyone could help me out.

The wireless card is ( Netgear WNDA3100 v2 )

Thanks for any replies which could help me out.
