[SOLVED] EZ Debug CPU light [SOLVED]

[TommyLer]

Hey. I've had this ongoing problem with my computer wich I cant seems to fix. The CPU light on the motherboard lights up, and the PC wont post. No signal in monitor.

My specs are:
Motherboard: MSI MAG B550 TOMAHAWK
CPU: AMD Ryzen 7 3700x
RAM: Corsair Vengeance LPX DDR4 3200MHz 16GB
GPU: ASUS GeForce RTX 2070 SUPER ROG Strix Advanced
PSU: Corsair RM650i, 650W PSU

I have tried:

• Reseating the CPU.
• Checking for no bent pins in the cpu and cpu socket.
• Resetting the CMOS
• Changing DIMM slots with both RAM, evern tried with only 1 of each in each DIMM slot.
• Quadruple checked the 8 pin CPU connector and the 24 pin ATX.
• Tried my CPU in another mother board (the RAM led lights up LOL)
• Tried with another PSU

Any other suggestions before I throw the damn thing out the 4th floor window?

Thanks in advance!

the light led up in the other board but does not pass cpu boot part means you cpu is defect so boot process could no go on .

When I tried it on my ASUS ROG Strix B450-F GAMING motherboard it was the DRAM led that was lighting up. Could that still mean the CPU is defect?

so it pass the cpu test and lock on ram i would use only 1 ram module in the second system to see if it pass all boot process before that i would reset bios on the asus board .

I will try to contact the store and see if they can find any problems with the CPU. I still got warranty on it.
I will keep you updated. Thanks for the info

Random update:
I tried to put my CPU in my ASUS ROG Strix B450-F GAMING motherboard and now the led indicators goes from CPU -> DRAM -> VGA then restarts back to CPU. This is an endless restart. What is going on haha

you have a gpu with the asus board and monitor plug to it also it seams like he does not find any drive so boot process could no go on .

You were right, it was a defect CPU. I replaced it with a Ryzen 5 3700 and the system is running flawlessly. Even with both ram!
Thank you for your help!
