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.

So your primary IDE channel is in PIO mode. You need to get that fixed. Try replacing the IDE cable for the primary controller and devices by a brand-new 80 wires one.
