hi,

i got a new issue. My rig is a half year old, and nowdays it is not turning on for the first power button push. then it doesn't turn on when i push the mobo's power button. It starts only when I unplug the cable from the wall and when I plug it in, suddenly everything starts without any buttons.

I refreshed bios, i deconnected the chassis power on button, i reset bios...
sometimes it starts for the first time, sometimes only with unplugging.
today it doesn't start with the unplugging, only when I swithced the psu off and on.
epu and tdp isn active and nothing is overclocked and never was. (neither xmp)

if it starts everything is fine and working well. with reset it resets well also. there is no overheating in the system and no faulty hardwares according to hardvare tests...

what can be the problem? why it isn't continous? can I harm my pc with this?

many thanks!
