my pc is connected to a power strip and when I turn the socket-switch on, my PC starts automatically without me pressing the power button. This issue started from yesterday out of nowhere. I have checked my power button it is good. I even removed the power button jack from motherboard header but the issue is still there. Sometimes Only the CPU fan is spinning and no display until I press the power button or short the two pins on motherboard.

Motherboard: Intel DP67BA
CPU: 15 3470
Power Supply: corsair vx450w.

when I plug my pc in outlet it turns on without me pressing the power button. BUT only psu fan and cpu fan starts spinning and windows boots when I press power button. And when I shut down my computer windows shut down but psu and cpu fan keeps spinning until I plug it out.
