I recently put together a new PC, but it's not powering up properly. When I hit the power button, the back fan lights up red for a couple of seconds and then it shuts off. After that, the RAM RGB lights activate. I tried unplugging the GPU, but it didn't help. I visually checked the CPU and it doesn't seem damaged. Here's my setup: 64 GB of RAM at 6000MHz, an RTX 5080 with 16GB, an AMD Ryzen 9 9950x3D, an MSI X870 Gaming Plus motherboard, and a MSI MAG A1000G PCIe 5 PSU. Plus, I've got a Samsung 990 Pro with 2TB storage and another 1TB M.2 with a heatsink. Well, aside from the RAM and M.2 drives, everything else is brand new.

Make sure all the power cables are securely connected. It’s crucial that nothing is loose. Also, can you tell me what cooler you’re using? It could be affecting the startup if it’s not set up properly.
Looks like you're using an AIO cooler, so check that it's plugged into the motherboard properly. Don’t forget about the PCIe power cables too; those need to connect your PSU to the motherboard for it to start up correctly.
