So I have this Dell Optiplex gx270. Whenever I boot it up it runs just fine for a few seconds then all power to my peripherals (keyboard, mouse, monitor, etc..) fails. The tower itself is still running but everything else just dies. Now all I'm really concerned about is getting my massive collection of music off of the hard drive. But if someone could give me a generalization as to what the problem might be, i would greatly appreciate it.
