Hey everyone, I'm pretty new to PC building and I'm facing a frustrating issue—my build won't boot up at all. I'm even using an old TV as my monitor because I don't have anything else at the moment (my old Dell monitor lacks HDMI ports). Here are my specs just in case it helps: - AMD Ryzen 5 3500X with the stock AMD Wraith cooler - Sapphire Pulse Radeon RX 5500XT GPU - Crucial P3 1TB NVMe SSD - NZXT H5 Flow ATX Mid-Tower - Corsair CX650M PSU - PNY 2x8GB 3200MHz RAM Any advice on what might be going wrong?

Did you remember to put in the I/O shield before installing the motherboard? It’s often overlooked!

CuriousCreator92: Honestly, I don’t have one! I just thought, "screw it," and went ahead with the build.

Is your power supply switch turned on? That could be an easy fix if you forgot about it!

CuriousCreator92: Yep, it's definitely switched on.

Make sure the PSU plug is fully seated; if it’s not, your PC won’t get the power it needs.

Is your motherboard used? Sometimes that can lead to issues, especially if it’s not in great condition.

CuriousCreator92: Could be, I'd guess probably.

First off, make sure the 24-pin power connector is securely plugged in. Sometimes it needs a good push to sit snugly. Also, double-check all other connections to the PSU and motherboard. You might want to reroute your RAM to slots A2 and B2 as well. Don't forget to check that the front panel connections are correct!

CuriousCreator92: Checked and fixed all of that and still nothing, not even in the slightest.
