How to Fix 'Error Q-Code 00' on ASUS Motherboard
April 29, 2024 - Instable Overclocking – If you overclocked the frequencies and voltages of your CPU, GPU or RAM, you can also expect this motherboard error to occur due to general system instability. In this case, you should reset your overclocked values back to their defaults and see if the issue is now fixed. As it turns out, one of the most common reasons that might be causing the 00 Q error code is an inconsistency that’s perpetuated by the CMOS (Complementary Metal-Oxide Semiconductor) battery. In most cases, this particular ASUS Q error is caused by some type of corrupted data that’s preserved in-between startups and needs to be cleared.

r/ASUS on Reddit: Can anyone point me towards a list of Q-codes?
April 21, 2024 -

I recently completed a new computer with a StrixX670E-E and, after a short time, it failed to boot and showed a memory error code.

I contacted support, sent it back, and they sent a replacement.

I reassembled my PC and, while it starts, it shows a series of Q-Codes (most appear around memory again) and I am hoping to try and figure out what is going on and, if possible, fix it before it breaks again.

However, I am unable to find a comprehensive list of codes and can only find people talking about them in various forums with generalized and surmised meanings. It would be really nice to have something more official (and which I could use to try and figure out how to diagnose the underlying issue and try and solve it).

Can anyone help me find one?

Meaning of Q-LED codes on ASUS motherboards
January 4, 2026 - It's important to know that not all ASUS motherboards have this system. Some only have Q-LED Core (which uses the power LED to indicate faults with different blinking patterns), and others, especially those from lower range or very oldThey don't have either Q-LED or Q-CODE, so you'll have to rely on the speaker or other diagnostic methods.
