Goes Not Responding

[xnd]

windows 7 pro, 64 bit
avast free a/v
comodo free firewall
(latest versions)
4 gb ram
i5 2.27gb cpu

Often, with no detectible cause I can see, the game goes not responding. This happened before I added any mods, btw.

I will be doing any random thing or nothing and it goes not responding. Then I have to use ctrlaltdel to end the task and wait minutes as windows tries to search for the problem but is no help.

Also, sleep mode, closing the laptop screen and bringing it back up, or using ctrlaltdel to go to the desktop, the game goes not responding, it won't ever bring the game screen back up.

I did have to set both the avast and comodo onto "game mode" or they just wreck it not responding when they do pop-ups.

Also, even when not "not responding", it will still hit these pauses, like walking along or fighting and then game pauses, won't move, the game has paused for some seconds. It does this a lot, very very annoying. Flash games tend to do this for me also but I have played games online that do not do this at all even though going through dungeons with other players.
