I'd consider looking at the tech boards and reading this post before starting your own there. Paying specific attention to the "how to post" link about using CoH Helper (link in the post may be incorrect, so use this one), and HijackThis when posting in order to maximize our fellow tech minded forumites in their effort to resolve your problem.
Off the top of my head, freezing could be due to hardware not being up to snuff (Power supply not distributing enough power to all components, not enough ram, etc...); Software issues (too many resource hogs running in background, drivers not up-to-date, etc); network related (although anything here would likely just result in disconnects); or any combination of things.
It's impossible to diagnose "game freezes" without additional hardware/software information, and CoH Helper and HijackThis will provide this information; posting in the tech boards will result in the most knowledgeable people in our community looking over your problem for you.

im not techy at all but for me my game would freeze up and i would still hear a loop of background noise or when i went to diff zone or zoned in or out of base and such it would take like four mins or longer to load. i upgraded my graphics card and added memory and i only have slight freezes every once in awhile.
I resently got a new computer and installed CoH on it. Every once and a while the game will just randomly freeze up. I uninstalled and reinstalled the game twice and the problem still occurs. Is there anyway to fix this?
