Problem for HP Pavilion 520c PC Desktop
Computer won't power up
My friend has a HP 520 N. We replaced the power supply but the unit will not power up. When you push the power (on/Off) button on the front of the computer, the processor fan begins to spin for about a second and then stops. Then nothing happens again unless you unplug the computer for a few minutes and plug it back in... then the same thing happens. I thought it was the on/off power switch and we replace it as well, but same result. What is wrong with this thing???

- forgive me what is SMPS. The power supply is new... plenty big, 450 watts... more that the one we replace.Solution #1

This happens sometimes due to SMPS failures. Try to change with other SMPS with same watts.
If it happens same then the problem with the board.
Try to consult a technition.
