ok this is odd for me, i built a new computer about a month ago but i am using an old power supply. With that in mind my computer wont post after i let it sit over night, until i unplug the power from the motherboard and plug it back into the board. Just wanted to know if that sounds like a psu problem or a motherboard problem.

Just in case you need it:
msi z270 gaming m3 motherboard
I5 7600k cpu
msi 1070 gpu
gskill 4x8 ram
win 10 home edtion
Psu seasonic 530watt (6years old)
