May be a problem with my motherboard. I have the msi b450 tomahawk max with a Ryzen 5 processor inside of a lian li mesh 2 case. I followed a fantastic tutorial on a similar build using the same case but a slightly different mobo and processor. However, my computer will not turn on. Everything is plugged in properly to the power supply, but nothing is happening. I'm at a loss and slightly worried that it may be the mobo.

If the system won't power up, I'd check the front panel header connection. It's possible you misconnected the power switch and the power LED leads.

About a week after installing a B450 Tomahawk Max MB I lost on board audio and video. I had to install a video card to get video, but I still don't have audio. Speakers and cables are fine. Help. Sorry about the double posting of this issue.
