But I do know that you can't fix things by picking up the machine and shaking it.
Don't be so sure. At an IT job long ago, I was trying to boot a machine, and the hard drive wouldn't spin up. One of my bosses came along, picked up the machine, and rocked it back and forth in the direction that the hard drive spins. It worked.
