So Earlier today I completed my build of my gaming pc, amd Ryzen 5 3600, tomahawk b450 max motherboard, nvidia GeForce gtx 1660 super with Corsair rm550x and I put the pc together over a few days and it was complete and I tested it and it turned on, all fans work fine etc all wires where correct and etc.. then I get my new monitor and plug it in connect the dvi and no signal… I feel like I’ve wasted a lot of time and money on this pc and I really need help fixing this problem. I’ve tried YouTube tutorials and unplugged and plugged everything! Even re opened the pc and checked everything was plugged in but no. Still dvi no signal! I can’t even load anything up and I even tried another monitor and the other monitor said no signal as well! I really need help, and I will give a million cookies to whoever helps me! Thanks a lot!!!
