Infinite (re)boot loop

[beaver18]

Desktop PC stuck in an infinite (re)boot loop.

PC: Ubuntu 17.10.1 64b, Asus Maximus VIII Impact, 6700K, 980Ti, Corsair 760i, 256GB 850 EVO SSD, Corsair Vengeance (not sure of specific model) DDR3 16GB RAM (2x8)

 

Last night PC worked fine, including multiple restarts & shutdowns.

Couple hours ago worked fine, including restarts of the system.

Now, after I powered it off few hours ago, and tried to power on again, it gets stuck in an infinite boot loop, in which it tries to starts for 1-2 seconds before shutting down and rebooting and repeating ad infinitum.

The duration stays the same, 1.5 seconds boot up, then shutdown & reboot, no matter how long I let it run.

Asus Maximus VIII Impact shows code 14, which I believe stands for pre-memory CPU initialization start.

I have two Corsair DDR3 8GB sticks, and neither were now or ever overclocked.

Based on my googling that the best option is to buy 1 ram stick, remove the two I have now, place the new one in, and see if it boots?

 

Baffled, in 4 years first hardware problem I have with this setup.

I know it sounds stupid, by try taking your RAM out and place it back in again (reseating it).

If that doesn't work, I would just use one of your sticks of RAM, see if it boots. If not place it into the next DIMM slot and try again, do this until you have tested all the DIM slots. I would then repeat this but with the other stick of RAM.

 

All the best

I will do that. It will take time due way the PC is built physically; I have to remove GPU and CPU in order to be able to remove them.

I removed GPU, but placed it back since I decided to actually remove CPU in order to be able to remove RAM sticks.

 

The PC booted to BIOS after removing and and adding GPU back in.

Then it booted to Ubuntu once I selected boot device from BIOS.

Then I tested shutdown and restart functions which it passed.

But after 5 minutes of running on Ubuntu (it wouldn't boot directly, it would only boot to BIOS) it suddenly shut down itself.

 

Funny phenomenon. I will proceed with removing the RAM sticks, I will just have to go and get a proper screwdriver so I can remove CPU/fans away from obstructing.
