so my old mobo and psu was crap so i changed them. i plug everything together and the my monitor didn't show any signal not even bios or something. then i unplugged all the cables and plugged them again i also tried to place my ram sticks in different slots but still nothing. i got 1 hdd and 1 ssd for windows and also my gpu fans spin for a sec and then stop so i tried to plug my monitor directly to the mobo still no boot .....
