Trying to do a build using AMD Ryzen 9 5900x CPU and the ASUS ROG Strix B550-F motherboard.
Got the system all built up, powered on....and nothing....dead...nothing out the hdmi video port. No boot to bios...
Took it all apart, and brought the processor, the motherboard, the DIMMs and the cooler to a local computer store - where they support commercial clients in addition to regular people, and also build custom PC's. THey've been in business many years. They confirmed that it was dead - no boot up to bios. As they are an Intel house, they didn't have any other AMD processors to swap in, to try to determine if it is due to the CPU processor chip or if the problem is in the motherboard.
Brought the parts there because I just wanted to have someone with lots of build experience to double check the problem - to make sure it wasn't a simple stupid error on my part - nope, the shop confirmed that either the motherbd or the CPU is bad.
So now I have a new replacement motherboard and a new replacement CPU processor being shipped. I figure to try out the motherboard and CPU first out on the bench, make sure it works and boots to bios befor installing it into the case. Once I find a working setup, I'll return the "defective" CPU and motherboard.
How should I approach diagnosing this problem...
Should I first try the new Mbd with the original CPU,
or maybe
try the original motherboard with the new CPU
and then last try the new motherbd wit the new CPU.
?
Any thoughts and advice or suggestions is appreciated.
