Cold Boot Issues

[DarkMatter]

Looking for some advice.

I'm currently experiencing some cold boot issues with the following system... Press the power button and the power LED lights up but nothing ever happens. Turn off and try again, sometimes it can be 3-4 times sometimes it can be right away. I've reset everything to default in the BIOS and then tried to set everything manually and it seems to make little to no difference.

What are the likely causes of such issues?

The system is
AMD 2400G
MSI Mortar B350M
16gb (8gbx2) Samsung B die DIMMs
Samsung 960 Evo SSD
Corsair RM550 PSU

Every update I can possibily find for the motherboard and CPU has been done.

I used to experience cold boot issues with my old PC (Intel 3570k asus Z77) but assumed it was the old motherboard... Can it be a PSU related problem or is it a common motherboard problem?

Thanks everyone for the replies.

I will try a new kettle lead. An easy long shot. I have a trusty HX520 in another desktop which I can swap around to test.

Sorry that was a poor explination. I shouldn't have said nothing ever happens just nothing happens.

My first thoughts was it must be a BIOS setting related problem so I reset everything to default values. Not sure if a full CMOS clear is different from doing a "load default values" in the bios? As for RAM speed I ran it at two different settings to try and rule it out....

Auto everything (sets it at fairly high timings at 2133hz 1.2v)
and
Manual timings/voltage from the sticks at 2133hz

seemed to make little difference.

As ridiculous as it sounds I'm tempted to switch over to using HDMI instead of DP to connect my monitor as along time ago I had issues connecting with DP to an old monitor and found HDMI to be more reliable... The monitor is a Samsung C27HG70 so shouldn't have any issues but worth a try.
