After I ran some test on my new case that I got I was trying to fix a fan problem that I had with it so for me to fix I had to take off the gpu so I can reach one the the fan cables from the mother board so I did a on and off test without the gpu so that means the display wasnt showing but when I fixed the fan problem and put back on the gpu the computer turns on and the rgb fans are wooking great but my keyboard mouse and monitor wouldn’t turn on too either. So if someone had this kind of problem or know hiw to fix it please reply to me thanks.
