I have been having a very odd problem with my MacBook lately. It takes a while for it to turn on, and when it turns on, it is for the most part frozen for a few minutes. I can move the mouse around and such, but no applications will open. My only application that opens on startup automatically is iChat, but now when it tries to open it has a pop up that says "Lost Connection with (my username)" Now, after a few minutes, I am able to open up certain applications like iChat, Yahoo Messenger, Microsoft Word, Safari, and several others, but they freeze up a whole lot with the colorful wheel. I quit the application after it thinks for a few minutes and once I quit it a pop up says "(application I was using) Quit While Being Irresponsive" with links to send the problem to Mac. Now there are several other applications that will not open altogether. I have Final Cut Express, and when I try to open it, it has the arrow under the icon on the dock as if it were opening, but it never does, and quits automatically after a few minutes. Then after my computer is on for a while or if I let an application run long enough being frozen, my screen goes grey and has a box with a message saying I need to restart my computer. I have no idea what the problem with my computer is, but it is aggrivating and very annoying. Please help!
