technical issue

My game hangs an average of 5 times per quarter(game freezes and sounds dissappear, though the commentators will finish what they are currently saying/talking about then total silence), ranging from 5-8 seconds each, i had the game for months now, and this started happening around last week, any tips on how to fix this?

Specs?

windows xp, 512 mb of ram, geforce fx 5500 256mb, 80 GB, Pentium 2.4

you might be short with your RAM to run recent games under XP that is very hungry with RAM ^^

try turning down your detail settings. also having alot of patches installed wont help. and lastly, close all the application running on background when playing live.
