Though Q-Code indicators on motherboards are good, they do not inform you a lot about what the fault really is. So we’re going to stipulate and clarify frequent motherboard Q-Codes for all the favored motherboard manufacturers.
Up to date: Nov 9, 2022 7:59 am
Trendy high-end motherboards are sometimes fitted with a Q-Code (error code) show, it’s solely job is to show error codes all through the booting technique of the PC. Chances are you’ll discover you probably have a Q-Code show, that the show cycles by way of error codes quickly earlier than it settles on the producer outlined “all good” code when your system lastly boots.
*UPDATED for Intel thirteenth gen and Z790 motherboards*
The difficulty with Q-Code shows is that there’s nothing to elucidate what the fault really is or the way you repair it. So we’ve determined to place collectively an inventory of generally encountered Q-Codes for all the favored PC manufacturers and provide some details about them.
In the event you’re out there for a brand new motherboard, now we have a couple of articles right here that might make it easier to determine on one.
The place is the Q-Code show on my motherboard?
It’s fairly onerous to overlook and is normally positioned someplace within the high proper nook of the motherboard itself. Not all motherboards have Q-Code shows, nevertheless, and a few resort to beeps or single lights to show errors.
In case your motherboard doesn’t have a Q-Code show, look to the proper center of the motherboard and there could also be a cluster of 4 lights labeled CPU, DRAM, BOOT, and VGA. These are additionally strategies of displaying errors. In case your PC doesn’t boot, seek the advice of these 4 lights while the PC is making an attempt besides.
What’s a motherboard Q-Code (error code)
Technically talking, the time period “Q-Code” is ASUS’ personal identify for the error codes which are displayed in your motherboard. Different producers, reminiscent of Gigabyte and MSI, produce other names that use. However on the finish of the day, they’re all the identical, they’re all simply debug or “error” codes.
The time period Q-Code has turn out to be so well-liked that you could be discover the overwhelming majority of PC fanatics calling each error code they see a “Q-Code” irrespective of the motherboard it originated from.
How do motherboard error codes work?
All motherboard Q-Codes are displayed on a chosen motherboard Q-Code show, able to displaying one quantity and one letter at any time.
The difficulty is that these shows on their very own aren’t very clever and simply cycle by way of codes based mostly on the present state of the system or the present stage within the booting course of. If there occurs to be an issue, the Q-code display screen will cease biking and show the present code, hopefully supplying you with a sign of what went unsuitable.
The concept is you’d then take the error code and, utilizing the motherboard guide or the web, analysis what that code meant. The concept is that error codes are far simpler than taking stabs at midnight and utilizing trial and error to diagnose defective PCs.
This could be true if there was some form of complete information round motherboard error codes, and that information advised you how you can repair them … Effectively, now we have you lined.
Z790 motherboard error codes (Intel thirteenth gen)
Intel’s thirteenth technology CPUs dropped on October twentieth, and with them launched the 700 collection of motherboards for Intel. Because of this there’s a complete new chipset to discover and the chance for it to be plagued with new Q-code points.
Fortunately, motherboard producers use a standardized set of codes for essentially the most half, so code 55 will imply the identical on an ASUS Z690 motherboard as it should on a Z790 motherboard from the identical producer.
All the Q-codes stay the identical, there are not any new motherboard Q-codes particular to the thirteenth technology or 700 collection motherboards. Excellent news then for diagnostics shifting ahead into the brand new technology.
ASUS motherboard error codes
Fortunately, a web site exists devoted to discovering ASUS fault codes. Faucet your code into ASUSQCode and get solutions in seconds.
The most typical ASUS Q-Codes are A2, 55, 99, 80, 76, 40, and 62.
- A2 – IDE detects: Attempt to connect ONLY the drive you could have/need to set up the OS to and ensure the boot order is correctly configured contained in the BIOS.
- 55 – Reminiscence not put in: it’s good to Set up the memory, if the reminiscence is put in guarantee it’s so correctly, or attempt different reminiscence slots for those who’re positive the reminiscence is correctly put in and the fault nonetheless persists.
- 99 – Tremendous IO Initialization: This can be as a consequence of numerous causes. This may very well be a faulty BIOS or defective motherboard, this additionally may very well be as a consequence of GPU error. Attempt to run the PC off built-in graphics or one other GPU/GPU slot. Within the first case, attempt to flash the BIOS to the newest model. If none of those fixes work, think about the chance the motherboard could also be defective.
- 80 – Downside with AI Suite software program: Attempt to uninstall the AI suite software program in secure mode, or roll again any adjustments you made previous to the fault code.
- 76 – PCH DXE Initialization (PCH module particular): It’s doable a USB machine is inflicting an issue, attempt disconnecting USB units one after the other, rebooting every time, to find out the problemed machine.

- 40 – System is waking up from S4 Sleep State: It’s because you could have configured Quick Boot/Quick Begin on Home windows 10/11. Attempt to disable Quick Boot/Quick Begin, leading to a full shutdown as a substitute of the S4 Hybrid state.
- 62 – Set up of PCH Runtime Providers: That is in all probability a GPU error, attempt plugging your monitor into your onboard motherboard IO and utilizing built-in graphics. If the fault disappears attempt utilizing one other PCIe slot in your motherboard to your GPU. If the fault returns in both slot on the GPU it’s the GPU at fault, if the fault returns on one slot then it’s the PCIe slot. An alternate methodology is clearing the CMOS and updating the BIOS.
MSI motherboard error codes
There’s no web site constructed particularly for MSI fault codes, however there’s a dump of ALL fault codes that can be found on MSI motherboards over on the MSI boards. Test it out for those who can’t discover your fault right here.
The most typical MSI Q-Codes appear to be 90, 0D, 92, A2, D0, and 40.
- 90 – Boot System Choice (BDS) section is began: This error can point out that you’ve a useless CPU or broken socket. Examine for socket harm and check out one other CPU you probably have one. You may also attempt the identical CPU on one other motherboard, if the fault persists attempt a distinct boot machine. If none of these options provide any reply it might be time to exchange your CPU.
- 0D – Reserved for future AMI SEC error codes: This error could be very descriptive, however it may well consult with RAM, GPU, CPU, and a complete host of different elements. This error can normally be mounted by updating the BIOS utilizing the BIOS flash utility when the PC is off.
