Your computer screen shuts down unexpectedly and a yellow glow shows up on your motherboard.
This problem began about a week ago and has been quite bothersome. At first, my computer’s screen turned off and the fans ran at maximum speed, eventually forcing me to shut it down by turning off the power supply. I managed to adjust the fans so they don’t run at full speed, but the yellow warning light still appears. I’m using DDR4 16GB RAM, and I’ve already removed one stick and left another in place. The issue seems to happen much more quickly—when both sticks are used together, it lasts only 4–6 hours, while with just one stick it drops to under 30 minutes before failure.
The yellow light appears on the CPU socket area, similar to the tag for the CPU.
If the problem lies with DRAM, remove it from its current slot and insert it into the A2 and B2 positions correctly. Make sure to align the pins properly before reinserting.
It seems the system uses either RAM or GPU memory. If changing the RAM affects crashes, go with that. After trying different configurations and slots, the next step is to test another RAM setup. Do you have another RAM unit available locally that you could use for testing? That would be the next phase of evaluation.
I thought you should always keep your slots in A2 and B2, but I haven’t tried the other options yet. I’ll check if that works. A friend had extra RAM and tried it—maybe that’s the problem. It seems to depend on whether you have one or both sticks, though. The crash time is what matters most. I’m still worried it might be the GPU, since I bought everything new four months ago without any issues. For testing, I could switch to integrated graphics and see if it helps.
You can use the RAM in other slots. Usually it's best in slots 2 and 4 (a2 and b2) for dual channel, but it should function anywhere if it's a single stick or placed in a1/a2 or b1/b2. Checking each stick in every slot is a standard troubleshooting method. This helps determine if the issue lies with the RAM modules or the slots. Trying another RAM setup can also assist in diagnosing the problem. If the problem continues no matter which RAM or slot you use, it suggests the hardware itself may be faulty. If it only works in one slot or with a particular module but not others, that slot or component is likely defective. If you lack experience, consider getting it checked by a professional repair service.
Responded late but everything was resolved. It turned out to be one of three possible fixes. I’m not keen on diving deeper now—just managed to get it working after cleaning the AIO a bit, reconnecting the cables, and swapping the RAM slots. I lost the dual-channel feature, but it’s functioning fine so far.
