Question pc wont start up consistently

May 27, 2022
when I start up my pc about 1 time out of 5 the fans will spin up, everything will turn on, my motherboard will have no error message and then while it has the bios logo everything turns off, any ideas? (I built about 2 months ago but I haven't been able to use it very much, I think its been doing it the whole time) system:
