I have a relatively new build, it worked fine up until today. I have an AMD Ryzen 5 2600 processor with an ASUS B450 Prime AMD Ryzen 2 motherboard, Crucial Ballistix sport LT 2666 MHz DDR4 RAM, and an MSI Radeon RX 580 graphics card. I was having a problem with my RAM (it was only detecting 4GB instead of all 8) so I powered off my PC and unplugged it and reseated my RAM. After doing so, I went to turn my PC back on but am not getting a display on my monitor. Everything turns on, graphics card, processor, fans, and I even get the lights on my motherboard, but nothing comes up on the screen. And also, my mouse and WiFi adapter are plugged into my motherboard but neither are coming on. It’s like the motherboard isn’t reading that they are plugged in. Can someone please, please help me. I payed almost $1000 and waited over a month for all of my parts and only got about 4-5 days of playtime. I want to avoid having to buy new parts but if it comes down to it then I guess I’ll have to. Can anyone please help me with this???
