How to Successfully Self-Assemble a PC: DIY Tips for Third Try Lit Up
The first attempt at installation was a bust.
Equipped with a motherboard and CPU combo, paired with a 5600 memory stick, the system refused to cooperate. After assembly, the motherboard’s indicator light skipped the self-check phase and defaulted straight to a steady yellow glow, while the fans whirred along as if nothing was amiss.
Despite following several troubleshooting methods recommended by customer service, none of them bore fruit. I visited the local computer market, testing the setup in multiple locations and even swapped out the memory stick—but to no avail. The evidence pointed squarely at a potential motherboard defect. With no other options, I filed a replacement request through JD.com.
The second installation attempt also fell flat.
Upon receiving the replacement, I promptly arranged for a technician to visit. Yet, the same stubborn yellow light greeted us once again. The technician, undeterred, consulted his senior colleagues online. We conducted an exhaustive series of checks on the motherboard, heeding advice from both professional technicians and online forums.
We even experimented with dual memory slots—but still, nothing worked. Just when hope seemed lost, a twist of fate intervened. While using only one memory slot, a casual brush against the power supply somehow triggered the system to boot into the interface. A flicker of optimism returned, leading me to suspect a possible issue with the power supply.
After reaching out to Seasonic’s customer service and conducting thorough tests, they confirmed that the power supply was functioning correctly and ruled it out as the culprit. At a loss, the technician decided to bring another power supply to test the next day.
The third installation proved triumphant.
When the technician returned and swapped in the new power supply, the yellow light persisted… To be honest, both the technician and I were utterly exasperated. Thankfully, we had a backup plan—a fresh Klevv memory stick. And just like that, the system sprang to life!!! Though it only worked with the 24th memory slot (the 13th remained uncooperative), we weren’t about to complain. As long as the machine booted up, we were satisfied.
🎊 The mystery unraveled: the motherboard and memory stick simply weren’t compatible. Oddly enough, I had double-checked with customer service beforehand, who assured me the memory was fully compatible… Clearly, a mix-up occurred somewhere along the line. Nevertheless, after a month-long ordeal, the installation was finally complete.
A heartfelt thank you goes to the proactive collaboration between JD.com and ASUS, which ultimately resolved the matter. I’ll be sure to update with a celebratory photo when time permits.

I completely understand that sinking feeling when things don’t go as planned! It sounds like you had a few tricky issues with the motherboard not POSTing correctly. Have you checked the power connections again? Sometimes it’s the little things that make all the difference.
I totally get the frustration of multiple failed attempts—happened to me too! Double-checking compatibility between components is key, but it sounds like you were already on top of that. Have you considered using a POST code reader? It could help pinpoint where things are going wrong. Good luck with the third try; hopefully, this one lights up as intended!
Thanks for sharing your experience and advice! I agree that a POST code reader can be super helpful—it’s definitely something I’m considering. Compatibility was tricky, but I learned a lot from each attempt. Appreciate your encouragement; here’s hoping third time’s the charm!
I feel your pain—building a PC can be so frustrating when things don’t work out! It sounds like you were close though; maybe double-checking compatibility between all components could help next time. Seeing that steady yellow light is always disappointing, but it’s good you’re documenting everything for future attempts. Good luck on try three—you’ve got this!
Thanks for the encouragement! You’re absolutely right—it’s all about checking compatibility and learning from each attempt. Documenting the process really helps spot small details that might have been missed. Best of luck to you too if you’re building your own PC—it’s a challenging but super rewarding experience!
I totally get the frustration with that “steady yellow glow” issue – it happened to me once too. It’s good that you eventually found a solution after visiting the local market; sometimes seeing things in person makes all the difference. Those troubleshooting tips from customer service are helpful, but hands-on experience is irreplaceable.
I feel your pain—building a PC can be so frustrating when things don’t work out as planned. It sounds like you had some serious compatibility issues or maybe even a faulty component since the second try didn’t go well either. Have you considered double-checking all connections and ensuring that everything is seated properly before giving it another shot? Good luck on the third attempt!
I totally get that frustration—building a PC can feel like a never-ending puzzle sometimes. It’s good to hear you eventually got it working on the third try though; perseverance really does pay off in these situations. Those steady yellow lights are always a head-scratcher, but glad to know visiting the local market helped sort things out!
Oh man, that yellow light of doom is so familiar! Had the same issue last year – turned out my RAM wasn’t seated properly even though it looked fine. Your persistence is inspiring though, third time’s the charm as they say!
