So I am building a new pc, i only have the motherboard, PSU and fans(LED). Being the dumbass i am, i plugged the case fan while the PC was running then it completely shut off, i tried reopening it but it only turned for like half a second, tried it a couple of times and still did the same thing, i waited hours and even the next day it still did the same thing, i put on the speaker there no beep at all, there is no burnt smell or any burnt spots so i dont know whats wrong, my PSU works since i tried the paper clip method. someone help plz my motherboard is MSI b250 gaming pro.
