tunes: Massive Attack - Mezzanine

Due to Windows XP Professional constantly freezing on me, I have to keep my messages short. I have not yet found the culprit as to why the computer keeps locking up. I just got interrupted b/c my sister had to tell me something stupid. Anyway, I took out the Firewire card b/c I think the computer was fine before I installed it. Other possibilities are memory, power supply, and video card. I could try uninstalling other applications, but this is going to be a very slow and long process.
