EZ-DEBUG CPU white LED.

[BojackHorseman]

Scenario:

 

So I recently upgraded my CPU, Mobo, Case, and Ram from my old system. The plan was to let my friend of mine who is starting to get into pc gaming use my old parts so I finished building my new rig and then built his. I reused my old case, CPU, CPU Cooler, and Ram (All this was already installed on the old case as I was using it up until 2 days ago,). I put in my old 980 GPU and my old Corsair RMX650 and his SSD and go to test the system and I get stuck on a solid white CPU LED. The ram RGB lights up, all the fans spin, but the PC wont go back this CPU LED. The system wont shut off either until I hold down the power button. I know none of these parts are faulty as I was just playing Forza 5 on them 2 days ago. I have tried just about everything I have read and have no idea what the issue could be at this point

 

List of troubleshooting:

 

Reslotted CPU (3/4 times)

Reapplied new thermal paste

Changed AIO power from CPU pump to CPU Fan header

Checked CPU and mobo for bent pins

Checked Mobo for any problems

Reslotted all ram (5/6 times)

Tried 1 stick of ram

Bios update via flash drive

Changed from LL120 Corsair fans to standard fans

Tried booting with no SSD

Tried booting with no graphics card

Tried all PCI slots with graphics card

Changed from a RMX650 power supply to RMX850

CMOS Clear w/ battery out for 5 minutes

CMOS Clear with jumping JBAT1 on mobo

Rebuilt the whole PC again

Tried different SATA ports

 

I looked over just about everything I can possibly think of or read and I am out of ideas of what could be going on. I know all the parts work as I used them 2 days ago and even tested the GPU in my new rig. The specs are below, I would really appreciate any help as he doesn't have any money to spend at the moment on new parts and he really wants to start gaming on PC.

 

Specs:

 

i7- I7700k CPU

MSI Z270 Tomahawk Artic edition Mobo

64 GB 3000 MHz DDR4 Trident Z RAM

Geforce GTX 980 (reference card)

Deepcool AIO

Samsung 970 EVO SSD

Corsair 220t RGB Airflow

Corsair RMX850 PSU

so it stays on cpu light? hmm.. have you checked the socket pins? if there is no issues with sockets pins you should try a different cpu..

I did test to see if the CPU is dead by placing my hand on it for a few seconds to see if it heats up. The CPU did get warmer after 10-15 seconds

I also don't have any spare LGA 1151 CPUs to test unfortunately
