New PC sometimes boots, other times VGA LED stays white

Aug 27, 2018
I recently built my first rig with the following specs:
CPU: Ryzen 5 2600
RAM: G Skill trident z series
PSU: EVGA supernova 650 G2

Everything was working fine until I had to move my PC to my new place. Now majority of the times I turn on my pc the VGA led light stays on and is white coloured. However every now and again after turning my computer on and off multiple times the computer boots up normally. During these successful boots sometimes the computer works fine until I turn it off, while other times it just freezes and then the VGA turns on again.

I have tried multiple things like reseating everything on the mobo, clearing the cmos, starting it up with only 1 stick of ram, the cpu and the gpu. All drivers are installed and the BIOS is up to date. Any other suggestions out there?

What is most interesting is how every now and again the computer actually works. Does that ensure that none of the components are dead/broken? Because that is my main concern.
I think that you were on the right track. When you moved the system, some connection that was secure is now unsecured.

Here are some check lists. Look for loose connections or anything loose under the motherboard like a screw. Were all of the standoff installed?

But there is another possibility. There may be something that is now grounding the motherboard to the case. Not necessarily the easiest to do, but I would recommend breadboarding the motherboard. Not only will it remove any chance of the motherboard grounding to the case, but it will help you identify problem components.

Here are several breadboarding instructions. Read through them and pick one to follow.
