Hey everyone! I'm building my first PC following a YouTube tutorial, but I'm running into an issue. After hooking everything up, when I power it on, the fans and lights start up just fine, but my monitor shows "no signal." I've already tried reinserting the RAM, switching cables, connecting directly to the motherboard, and even tested it on a TV to rule out the monitor. I really hope I'm overlooking something simple because I'd rather not take it to a shop. Here's the list of components I'm using: Intel Core Ultra 235 CPU, RTX 5070 GPU, Z890 ATX motherboard, 64GB DDR5 6000MHz CL34 RAM, Montech XR case, 750W modular PSU, and two 2TB SSDs.

Given that you've tried everything, it might be worth resetting the CMOS. Sometimes that helps resolve initial boot issues.
Also, make sure all the power connections are properly secured, especially the CPU power. It can cause the system to power on but not send a signal to the monitor.
Did you check if the monitor is connected to the motherboard or the GPU? That's a common mistake for first-time builders!
