Hi guys got. A problem right now first build. B450 won’t display and red light cpu :(
Could you please clarify little a bit more? Please share your part list because the one I see on your profile only shows a Ryzen 7 2700 and MSI's X470. Sounds like though if your red LED is glowing as the CPU then it's an indication to be an issue with the CPU. Assuming you have a Ryzen processor, carefully check for any bent pins. May need to gently fix bent pins with a pair of tweezers if able to, otherwise return it.
you should be able to bend the pins back
Yes, majority of the time. Unless the pins were bent too much and came off then that's a pickle.
