The build started successfully but restarted after BIOS. It remains stable in BIOS, allowing changes without crashes or failures. This happens repeatedly. A boot warning appears saying to connect at least one 8-pin ATX_12V connector to the PSU for stability. The problem persists even when switching PSU, RAM, or plugging in different 12V connectors or using a USB with installation media. Re-seating the processor, clearing CMOS, and updating BIOS didn’t fix it.
Any advice? Should I take my motherboard to a repair shop?
Following the BIOS flash, did you also carry out a hard reset? This is occasionally required to make the BIOS recognize the hardware tables properly. Even after updating the firmware, some devices still fail to accept new settings, making a reset the most effective solution. Please attempt this step precisely as described.
Additionally, there are no dedicated repair shops for motherboards. Even specialized electronic repair services usually avoid working on motherboards unless it involves simple fixes like replacing a damaged capacitor. Given how intricate these boards are today, attempting repairs is almost impossible.
Following the update to the latest BIOS, did you also carry out a hard reset? This step is sometimes required to prompt the BIOS to refresh its internal hardware configurations. Even after installing a newer firmware version, certain devices may still fail to accept new settings, making a reset essential for resolution. At the very least, attempt this process precisely as described.
Additionally, there are no dedicated "repair shops" for motherboards. Even specialized electronic repair services typically avoid working on motherboards unless it involves extremely simple fixes, such as replacing a damaged capacitor. Given how intricate these boards have become, attempting repairs is often impractical or impossible. Manufacturers usually opt to replace faulty units rather than attempt fixes, placing the responsibility on consumers to send defective boards for warranty service instead of seeking repair. Repair services generally focus on troubleshooting and part replacement, which most people can handle themselves now.
However, it might be reasonable for those without replacement parts to consider sending the board for warranty service if it's malfunctioning. Repair shops rarely perform comprehensive repairs; they usually deal with basic diagnostics and part swaps. Therefore, before proceeding, try the hard reset thoroughly.
BIOS Hard Reset procedure
Turn off the device, power down the power supply, and disconnect the PSU cable from the wall or power source.
Remove the CMOS battery on the motherboard for roughly three to five minutes. In some instances, taking out the graphics card may be necessary to access the CMOS battery.
While the battery is removed, keep pressing the power button on the case continuously for 15–30 seconds to discharge any remaining charge in the CMOS circuit. Once the five minutes are complete, reinstall the battery, ensuring it is oriented correctly as it was removed.
If you had to remove the graphics card, you can now reinsert it, but be sure to reconnect any power cables and your display cable as well.
Reattach the PSU power cable, restore the power supply, and power on the system. The display should show the POST screen with options to enter CMOS/BIOS setup. Launch the BIOS configuration tool and adjust boot settings for Windows or legacy systems, depending on your operating environment. Save your changes and exit.
If the system successfully boots, you can proceed further—such as navigating back into the BIOS to configure additional settings like Memory XMP, A-XMP profiles, D.O.C.P profiles, fan settings, or other custom parameters that may have been lost during the reset.
In certain situations, after resetting the BIOS, it might be necessary to load default or optimal settings to fully reinitialize the hardware tables.
It worked! I wouldn't have guessed at a hardware issue since the BIOS confirmed the right components. Thanks!
This situation is unusual. Even after attempting to replace my 64gb 6400 ram and resetting without using docp, the reboot problem continues. It seems the ram might be defective, though I wouldn't expect difficulty accessing BIOS in that case.
It doesn't necessarily indicate a faulty memory. It could mean the memory you're attempting to install isn't suited for your motherboard. This situation often arises due to differences in compatibility, which is why manufacturers maintain detailed QVL lists and why companies like Corsair, G.Skill, and Crucial provide more comprehensive compatibility information.

2 paired sticks. Identical problems with each stick in all slots.
Unfortunately, it seems the problem isn't resolved. I reverted to the G-Skill I received initially and reset the CMOS as instructed, but the system now restarts repeatedly.
Edit: I reviewed the T-group QVL list and realized I inadvertently purchased incompatible RAM. Moving forward, I'll rely on the backup G-Skill (which shows the correct MMO in the QVL) for the near future. A valuable lesson learned about double-checking RAM compatibility. As before, the reboot cycle persists when using the G.Skill RAM.
After experimenting with different reset and BIOS configurations, I now have a stable boot process, though it isn't straightforward. If I perform a hard CMOS reset, restore the defaults, then switch to UEFI/Standard mode and enable ASUS boost, I achieve a clean start where all components, including my GPU, work properly and consistently. However, earlier attempts result in a stalled VGA display during boot. Repeating this sequence consistently leads to a successful full boot.
4090 FE. When no gpu is installed, it (usually) goes into an infinite boot loop rather than stalling at vga light. Nothing consistent, however, and I've gotten successful repeat boots without vga. The same reset loop gets a boot with or without gpu installed.
Whelp, now every third or fourth boot is locking with a boot light on. This problem is getting real weird
...and now the reset is going into infinite boot loops (sometimes). Rip.
