Issues Booting Up New PC Build

Bobby King · 3 Feb 2021 at 01:37

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?

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.

Are you sure it is max motherboard?

also clear the cmos of the board boot. The first boot takes a very long time

what ram are you using? Try with 1 stick in the B2 slot.

you absolutely sure you plugged all the cables in the correct slot?

check CPU cooler is seated properly etc.

You may need to upgrade the BIOS on the the board via a USB stick. I had to do that on my MSI B450 board Gaming Pro Carbon before it would accept my 3600.
