Okay so I've had this mid-2009 MacBook Pro (2.53 GHz, 4GB RAM) since June and it's been running relatively well up until a few days ago when it started rainbow pinwheeling on me while using Firefox, GarageBand, or Finder. I have VMware Fusion running Windows 7 but I'm not sure if that's what's causing the problem.
Some things I usually do that might be deemed suspicious are:
- I use InsomniaX when I need to keep the MacBook from sleeping
- I let the MacBook sleep rather than turning it off when I'm not using it
I haven't encountered many heat-related issues, luckily. Do you guys think one of these habits is causing the slowdown or is it something else? I tried restarting the computer and up until now I haven't noticed anything but I wouldn't put it past it to start chugging again.
