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.
