Assemblements CPU - Intel i7-13700k cooler - Coolmaster PL240 Flux Mobo
Gigabyte Aorus B660 Master DDR4 GSkill Ripjaws V Series (2x32MB) DDR4 3600 GPU
GeForce RTX 3060 PSU
Corsair RM850 Memory
Samsung 990 2TB M.2 x2 Case
CyberPower CFI Full ATX (purchased in 2014)
Windows 11 Home (boot not installed yet)
After installation, the machine powers on normally with all fans spinning. No display appears. The B660 shows four status lights: CPU, DRAM, VGA, BOOT. Once both RAM sticks are seated, the lights alternate between CPU and DRAM, and the system restarts every 30 to 45 seconds. With only one stick installed, just the DRAM light stays on, no restart, still nothing visible on screen.
I've tried several steps:
- Reassembled CPU
- Replaced RAM slots
- Swapped CMOS battery
- Used different RAM (Corsair Vengeance LFX DDR4 3600)
- Switched PSU to Termaltake 750 from an older PC
- Reseated all connections
- Cleaned RAM pins and slots
- Removed GPU, used only the Mobo
- Disconnected M.2 slot entirely
Only the Mobo powers on with RAM installed, no fans or other parts. I’m uncertain if I missed something and need advice. This is my first build since around 2014. Thanks in advance.
Let it rest for a while. It may need a few minutes for any changes to appear.
I don't agree with this assessment. I haven't encountered such a lengthy process when checking a display, RAM training, or system functionality. It likely indicates a CPU problem, probably caused by a misaligned, bent, or missing pin. Recommend gently removing the CPU and inspecting the socket for pins that are misplaced, bent, or absent. Because it's a new build, consider filing an RMA if you notice any pin issues.
Processor and socket appearance are satisfactory, though I might have discovered a problem only after testing. It seems the socket is compatible with 12th generation processors, while my model is a 13th generation; therefore, updating the BIOS may help determine if that’s the root of the issue during startup. More to follow
Yes - A missing chip leads to the issue. If a BIOS update exists for it, install it and observe the outcome.
This might happen occasionally, but 15 minutes signals a genuine concern since the outcome turned out this way. It's fine if it only takes a couple of minutes, as I've experienced before. But lasting 15 minutes suggests a serious problem that needs attention.
