Build Advice New PC Build CPU and DRAM LEDs Light Up, Frequent Crashes and BSODs

[nohohero]

Hello all, I'm in desperate need of some help.

Built my first gaming pc a few days ago and it's been somewhat of a nightmarish experience so far. When I turn the PC on, the motherboard's CPU light turns red and the DRAM light turns yellow, this lasts about 5/10 seconds then they disappear and the computer boots normally. If I restart the computer, the same thing happens except for only the DRAM light is on.

In terms of issues with the functionality of the PC, I was able to install Windows, connect to WiFi, and install and use web browsers, update graphics drivers, and install a game for testing. I did experience numerous crashes and blue screens of death throughout these processes though. When I boot the game though it either crashes immediately or soon after getting to the menu, I think the furthest I got was finding a game and then it crashed as I was entering it.

Feeling very stressed and disappointed since I've sank so much money into this and nothing seems to be working. Here are some of the attempted solutions I've tried so far...

• Unplugged and re-plugged everything, ensuring they were secure.
• Updated the BIOS many times and tried several of the latest versions.
• Cleared CMOS many times.
• Inspected the motherboard pins (all looked ok to me but I took a picture just in case I'm missing something), re-seated the CPU, and reinstalled the CPU cooler.
• Re-seated both RAM sticks.
• Tried booting with 1 RAM stick in slot 2 and then no RAM stick at all.
• Uninstalled Windows 11 and fresh installed Windows 10, reinstalled bios after.

Any idea what my next steps might be? Hoping I've been dumb and missed something which might help or at least clear up what the issue is. Happy to answer any questions or share any pictures of course.

Apologies, I was having some issues with my post. Let me update it.

What is the exact model number for the Corsair RAM that you purchased? It should look something like this: CMK32GX5M2E6000C36

Here is the supported memory of your motherboard verified by MSI. Its not 100%, but this sounds like a RAM issue. If it is indeed the RAM, it could be three possibilities. Firstly, the issue could be caused by the RAM not being on the QVL list for the motherboard causing instability. Second, it could be faulty RAM. If the RAM is faulty you could either return it for another kit on the QVL list, or RMA it with corsair. Third, it could be the motherboard has some issue between the RAM and the CPU, or the CPU has a faulty memory controller. First and second are significantly more likely, third is a diagnosis of exclusion. This means that you have verified that it can be nothing else except for either the motherboard or CPU are faulty. Most of the time its the motherboard, but rarely a CPU can be faulty.

Woah it's not on the list...


The model number of mine are is: CMK32GX5M2E6000Z36

This is them: https://www.amazon.co.uk/dp/B0CJ8ZHMVF?ref=ppx_yo2ov_dt_b_product_details&th=1

Is this almost certainly the issue? If so I'd be equal parts embarrassed equal parts relieved.

It would be my best guess, you may want to wait for others feedback. I would get a kit that is on that list for your motherboard and return the Corsair kit that is not on the list. Any 6000 M/Ts cl36 or lower kit should be fine. I prefer Corsair and G Skill RAM.

Have you monitored the temperatures of the CPU at any point?

Ok it's worth a shot, I'll order some RAM that's on the list. Thanks so much for pointing that out.

I only got a glancing look whilst in bios and it was around 50 or 60 in there i believe, that probably doesn't help. Would a high temperature give away CPU issue?

If it's of any use, I just looked at pins and CPU another time and they look absolutely fine from what i can see (and from my understanding).

Worst case scenario, the new RAM has the same issues and you can exclude a potential issue off the list and know that RAM you got is compatible with the motherboard. Check my post again I made some general recommendations for what RAM to get off that list.

Regarding the CPU temps the implication is that if you mounted the cooler poorly enough you could be overheating the CPU and that can cause BSODs and shutdowns. Seems like you mounted it multiple times and had the same issues though. That cooler is not the best, but it would allow the PC to function at least.

The red cpu light appears immediately on boot, would this indicate the CPU hadn't had time to overheat yet so that may not be the cause?

Also could the red CPU light be a product of ram incompatibility? Or is that indicating more likely cpu issue?

Thanks again for your time and input.

The CPU light could be either RAM, CPU, or motherboard related issue. Its not very specific because any one of those parts having issues can cause a CPU error led light up. It could be the CPU, but like I said, defective CPUs are rare. It is more likely a CPU adjacent issue like RAM, motherboard defect, bent pins, et cetera.

Hey!
Did the Ram change fix your problem or it still persists?
And if you were able to fix it some other way, can you please tell me how?
