100% CPU with linksis wifi usb card 2.4 ghtz

ok i am new here and reading what you is sayingjust go to fire fox it way better and internet explorer is a free gate way for viruses but that aint y i hear. I have a problem i have a lynksis wifi usb card 2.4 ghtz and when i plug it in my cpu usage spikes to 100% it goes like this 0 to 18 to 100 over and over again but when i take the card out it stops and goes back to 0 toa t most 12 % i need ideas is it the card or the computer cuase i really would like to play Sudden attack without lag for heck. but also may i ask could it be the game or some updates i received. Cuase it worked one (Sudden attack) and then i turned my comp off but it didn't shut down so i manualy shut it down then the next day i try to play it was lagging in the game also it did a game update and a patch that next day so is that the prob or the wifi stick

 

i fixed it
it was the wireless monitor taking up the process power lol no biggy it all fixed now so no worries
