Please read the complete post for proper context

 

CPU	AMD Ryzen™ 7 2700X
GPU	ZOTAC GAMING GeForce RTX 2060 AMP
PSU	CORSAIR RMX RM1000X 1000W ATX12V / EPS12V 80 Plus Gold Certified Full Modular Power Supply
RAM	G.Skill Trident Z RGB Series DDR4 Memory Module (8GB X 2pcs, 3200Mhz)
MO-BO	B450-GAMING-PRO-CARBON-AC
CASE	NZXT S340 Elite

 

I built my PC with above components in India.

I recently moved to US for my studies. So, I got it shipped to US.

 

Before shipping I disconnected the PSU, GPU and RAM form the case and packed the rest of the PC as is.

After receiving it here in US, I assembled everything and turned on the PC.

 

There were some spark/crackle sounds. I immediately turned off the machine and try to figure out what happened.

I couldn't see any smoke or visual damage on the mobo. But there was burnt smell for sometime.

I speculated that it might be RAM.

 

I dared again to turn the PC on. This time my PC turned on properly without any issue but there was no POST.

The RAM EZ Debug LED was on for 5 secs and then getting turned off after 5 secs every time I turned on my PC.

 

I faced this before. Last time this happened I cleared the CMOS and it started to POST normally.

I did the same for more than 5 times this time, still no POST.

 

I tried updating my mobo bios, still no POST.

 

So, I searched around and found that re-seating the CPU worked for some guy.

I tried to remove the CPU Cooler, the CPU was STUCK to the cooler very tightly. So, I searched online to how to remove

CPU that is stuck to cooler and found a solution where isoproponal was used to remove the CPU.

So I did the same and successfully removed the CPU from cooler.

 

Now, I re-seated the CPU, connected all the other components and turned on my PC.

This time DRAM EZ Debug LED was on. I tried all the combinations of RAM configurations

(single and dual) channel and nothing worked.

 

It was late at night so I disconnected PSU and left the PC as is and went to sleep.

 

Next day right after waking up, I connected my PC to PSU and turned on the machine and found that CPU EZ Debug LED was on.

I re-seated my CPU several times and didn't work.

 

I breadboarded the machine with CPU+cooler, PSU and 1 RAM stick on the mobo and turned it on.

Still the CPU EZ Debug LED is on.

 

Don't know what to do. Please help.
