The game freezes when someone attacks. All settings are on lowest, does this mean my pc cannot support sc2?

I froze 3x in a row, however I just played a full 18min 1v1 and it was perfect.. any ideas why it freezes sometimes?

what video card / processor are you using?

man there's like 5 million reasons why this could be happening , you need to post your system specs for us to know if your system can handle it
some general things to try : update video card drivers, make sure no other processes are running in the background, increase your virtual memory in windows, make sure u have most recent version of direct x, reinstall windows, format hard drive, run disk defrag, monitor system temperature/video card tmp, etc etc etc

turn ur hacks off
