Hi, your Z690 Gigabyte Arous pro is supposed to light up automatically when powered on. It seems the default behavior might not be working as expected. Since your LED fans are already running and you can’t access the BIOS, the issue could be with the power circuit or a faulty boot sequence. Check the power connections and ensure the motherboard is properly seated. If the problem persists, there might be a hardware issue that needs professional attention.
Is the POST Code display stopping on any particular number? What are your full specs?
When I power on the system, the post code keeps producing random numbers each time. This is unusual for my first MOBO with a post code. I noticed the Arous LED on the heatsink should illuminate when the computer starts up, but it seems to stop at C1. The status red LED appears to be connected to the DRAM. I suspect a RAM issue, so I’ve tested each RAM module in different slots—even using a single RAM and no RAM at all. Still, I can’t access the BIOS and see any display. Here’s what I have: Intel Core 12900K, Kingston Fury beast 5200mhz, 16x2 DDR5 RAM, Corsair rm750x CPU cooler, Master 360 illusion. I tried without the 3080 chipset but got the same problem with my old 1060.
You're referring to the timing of the post-on activation and some unusual behavior during installation. It seems there might be a mix-up between components or a misunderstanding about the setup. The Arous RGB Arous LED typically lights up when the system powers on, so if yours doesn't glow, it could indicate an issue with the power circuit or motherboard connection. The tight screws and difficulty removing the heatsink suggest possible physical damage or improper installation, which might affect cooling. Regarding CPU and RAM quality, modern components generally have high reliability, but factors like manufacturing defects or improper handling can still occur. Always double-check connections and consider testing with a known-good setup if unsure.
POSTing indicates successful Power On Self Test. This results in the AORUS display that lets you access BIOS settings. The driver currently installed on the M2 screw is Philips 0. Screws typically don’t perform the function you’re describing. It seems the issue may lie with RAM or CPU—probably a 70/30 chance. If possible, please ask the shop to assist in identifying the faulty component.
Okie, I didn't see the BIOS or the AORUS screen, no display input. I used a small Philips screwdriver—one of the screws came out easily, but the rest were really tight. Is it normal to have all the fan LEDs on when the computer isn't powered on? Just switching the power back on my PSU makes the fan LEDs light up.
The fan LED is linked to a separate controller or PCB, such as a Corsair Node/Commander or TT control, not the main motherboard RGB headers.
