WTF

How come my computer skips in videos and cursor movement? Every time this occurs, the next thing that happens is any music i'm currently playing slows down and skips ALOT when I launch Firefox.

The only remedy I've been using for this problem is re-installing windows. The problem comes back whenever it wants to. This time my video and cursor are skipping 4 days after I re-installed windows.

1. Stop using Internet Explorer
2. Get rid of all the system tray bullshit; bullshit useless system tray crap is bullshit and useless
3. Check that your hard disks are in Ultra-DMA mode
