I have a problem!!! my computer doesnt run wow !!!@!!!@! heres the story: BTW: i have wireless connection on my desktop. i have a little piece that plugs into my usb port.

when the new "pre cataclysm" patch came out, my computer cudnt download it. the download wud get to 50 percent, then the connection on my computer would just disconnect.

few weeks later.. we switched to verizon fios. now the patch is downloaded and i can sometimes log into wow. howeverrr..most of the time i click "enter world" it either doesnt log me in, or i get in, lag like crazy and then disconnect from the servers

when my screen feezes my character is still doin what he was doing before it froze. for example: if i click a spell and the screeen freezes, he will be frozen but his hands will be lit up with the spell..so basically hes casting as its frozen.

is this my connection? or ram? also what is ram and how expensive is it to get more? how do i check my ram to see if i have enough? my computer is sopposed to be really good plus its a desktop, so idk if it could be ram..

SOMEBODY HELP ME!!! PLEASE

thanks
im not sure how to check wut speed its running at..is the cpu usage?? if so its 63 percent
