I just finished building my first ever gaming pc and when I went to start it up the fans, the graphics card and everything turn on, even the motherboard lights up. But, when I tried setting up the monitor mouse and keyboard to start working in the BIOS settings none of them work. Monitor says 'No Signal' and mouse and keyboard won't light up. I'm still completely new and am sad and lost on what to do because I worked so hard and it's a decently expensive build. Some places I read said it could be an issue with the PSU but it's a brand new psu and everything else is on. Please help!! /:
