z690 configuration - 12700k with CPU instructions every few seconds during startup
I spent a week off with my computer. Much activity was happening. I finally completed what I started. I made a hole in the ceiling, added a fan case, and installed a ceiling fan. Successful. I restored the breaker and got this. The system ran code 00 CPU then other codes, then back to code 00. It kept looping forever. Here’s the link to a video: https://1drv.ms/v/s!AvsO0rkUe83siJpEx9q4DJI6HGQfKw (one drive video). It won’t boot or show anything. It just loops. I tried turning off power and removing the battery for a minute. Cleared the CMOS with a button. Swapped the power supply. Pulled one or both RAM sticks, moved them around, removed all cables, unplugged the SATA connections, and flashed the BIOS to the latest update. The flashback worked, but didn’t fix it. What’s happening?
This situation clarifies a few possibilities. I’m hoping bad news is handled well.
1) The fan shares the same circuit as the computer and interferes with the line frequency; using a power cleaner or UPS could resolve certain issues.
2) The fan, featuring a large slow electric motor typical of older models, generates EMI that disrupts other devices. If this is true, turning it off will likely fix the problem. But if turning it off also powers off the computer, proceed to option 4.
3) Both the fan and your computer are energized on the same circuit—or the entire house’s electrical system is weak or overloaded, making the fan the breaking point. (For a vivid illustration, watch “A Christmas Story”).
4) Your own electrical work, or that of a previous owner, was improperly done, causing issues ranging from 1 to 3. The real fix usually demands a licensed electrician and significant funds; I think it’s unlikely you’ll manage this alone.
5) A mix of these factors (1-4) could be at play, but the genuine answer often requires a certified electrician and substantial investment.
The fix for options 1 or 2 would involve a dedicated circuit with its own ground, which is generally more costly than a cleaner or UPS, though a separate ground may help unless the wiring is outdated.
(For a clearer picture, see “a Christmas story”).
3 May need a bigger service upgrade, which adds to the cost. My experience was $5,000.
I’d suggest removing the fan and restoring things as they were, but option 4 offers more reliability and long-term benefits—unless you’re willing to spend a lot.)
It makes sense. I relocated the computer to a different board to verify your hypothesis, yet the issue persists. 00 cpu, additional codes, then loops, while the CPU fan is running high. I'm thinking about reassembling the system.
It might simply suggest the issue is worse than it seems. Or it could be related to the system. The schedule hints at the first option, though correlation doesn’t equal cause.
I experimented with several solutions this morning. Replaced the CPU. Swapped RAM sticks in every possible setup. I observed that the system bypasses code 00, jumps to 26 or 28, then restarts. I purchased a DDR5 RAM stick from PC Part Picker and ordered a 12-core processor. I plan to swap those in. If neither of these fixes the issue, I’ll attempt to get a warranty for the motherboard from Asus.
Are there any additional high-power devices like electric space heaters? It seems more likely someone experienced a power surge. Did the computer stay plugged in during your electrical tasks? Updated September 3, 2022 by Bombastinator
ya, but the breaker was off. Computer is connected to a zerosurge 8R15W.
