I recently took it all apart and cleaned all kinds of horrible dust out of it, and put new thermal paste on the CPU. Think that might have anything to do with it?
If its not the PSU, and its not the power button, what could it be?
EDIT- Just to clarify, once the power is hit on, everything starts running hardware-wise for a second or two, then shuts down and does the same thing again. There is no video output.
