Okay, so a while back I had posted about my Cube not powering up. I got a replacement VRM, but that didn't seem to help. I then got a new power button, and that seemed to work. Problem is, the Cube powers up for a few seconds, the hard drive spins up, and everything lights up, but then it shuts down again before showing anything on the monitor. Then it reboots and goes through the process again. I've tried booting it up with both the original processor and the new upgrade I have, but it goes through the same processes either way. I've reset the motherboard as well, after swapping processors. Anyone know what's going on?
