PC Froze then it couldnt boot - EZ debug lights cycle between CPU and DRAM

Go to solution Solved by Lemtea,

2nd dimm is dead. it is not uncommon for ram to die suddenly (at least its more obvious than intermittent stability issues). Your options are to continue with the single stick, try to find a ram stick with the closest spec/revision to replace the dead one (no guarantee that you will be able to run the rated speed and its possible the other stick may not last much longer) or replace the memory with a new kit. Given the pricing of ddr4 I would be inclined to suggest just replacing the entire memory kit as it would be the only way to ensure you have a memory kit validated for the rated speed.

Hello,

-I've been using this PC for almost 6 years. I've had no modifications to it since then, except changing thermal paste couple years ago. And a new UPS more than a year ago. It's been working fine(gaming/work/etc).

-Yesterday i was just normally using PC, editing a post on discord while downloading a mod in the background when my PC froze. Had to shut it down.

-After i powered it, it would start for a couple of seconds and turn off and repeat this cycle until i turned the PSU off.

-Also during this i noticed the EZ debug lights on the motherboard, they would cycle between CPU and DRAM and glow white. The glow would be slightly longer on DRAM.

-After this i reseted bios with the jumper cap. After powering it back up it would not turn off like before, but the EZ debug lights would keep blinking the same way.

-After that i removed the GPU and moved the ram sticks from A2/B2 to A1/B1 it didnt work, same thing like before.

-After that i removed the 2nd ram stick and it booted up. Later it also booted up with the 1st stick in another slot.

-After that i removed the 1st ram stick and tried the 2nd ram stick in the same slot, it wouldnt boot, same thing like before. I tried changing the slot to A2,B1,B2 all didnt work.

-I've also ran the memory diagnostic for the 1st ram stick and it went fine.

 

Is my 2nd ram stick faulty? Is it normal for a stick to just die/brick like that? Or can it be something else? Do i just have to get a new set of ram? Can i test/check something else?

Probably have to buy a new set of ram like you said. Not sure if to go 2x8gb or maybe "upgrade" to 2x16gb. I do usually have a lot of tabs open, stuff does use up more ram now, but my pc is on the older side (6y) and in a couple of years i should be getting a new one. And which ones too, which are available at what price...hmm so many questions.

Going to 32gb of ram really depends on your use case. For a purely gaming machine 16gb is just fine but that may change with some newer games and how much other stuff you do with your pc. Best way to see if you will benefit is to look at memory utilisation while you are using your pc to see if you are running out.

I have to get a set of new RAM then. Does it matter if the exact ram model isnt on the MSI mobo supported memories list? https://www.msi.com/Motherboard/Z390-A-PRO/support#mem
It hasnt been updated for almost 2 years.
I am leaning more towards 2x16gb since i do usually have a lot of stuff open and stuff does require more memory nowadays. I was planning on trying some video editing too, would help with that too. And i do plan using this PC for at least a year or two more. Although 2x8gb is prob enough hmmm. The prices here are mostly higher than rest of EU and the stock of ddr4 doesnt look too good. So not much choice.

 

UPDATED LIST

 

all of them are 2x16gb 3200-3600 (not sure if all can go that high, mobo support)
