Issues Booting Up New PC Build

[Bobby King]

Hi I just built a new PC, I’ve made sure all the cables are in ok and I’ve unplugged them all one by one attempting to fix the issue. I have a 500W power supply and a B450 Tomahawk max motherboard.
The pc starts up for a second and the fans start spinning, but then they stop.
Can anyone help, I’ve been trying for hours.

100% sure that the motherboard has bios support for the CPU? What is the CPU?

Ryzen 5 3600

You have been trying for hours to press the button and seeing fans spin up and nothing happens?

that must have been tedious. Usually it takes someone 2 or 3 goes to realise something is wrong and that’s about 3-5mins.

you need to give more information about your build.

Sorry. I’m using a Ryzen 5 3600 CPU with a MSI B450 Tomahawk Max Motherboard. The GPU is a MSI GTX 1650 and the PSU is an evga 500w BR. The case is a Corsair Spec-Delta.
