Recently with an update for Itunes, when I go to eject my ipod Itunes crashes, and I cant do anything with it, I have to just turn my computer off and unplug my ipod. I have wondered for a while if my power supply has not been working right though. I have 4 hard drives, an athlon XP 2400 processor, a swapable tray for an extra hard drive, 1 DVD burner, and 1 cd burner, and a GeForce 5600 graphics card. Would a faulty power supply cause my machine to run slower, just not so good in general? Any help is greatly appreciated!
