Computer fails to start after a power cut, requiring a BIOS reset to proceed.
Initially, I've already swapped out the CMOS battery!
The setup details are as follows:
Processor: Intel 12900k
Motherboard: ASUS ROG STRIX Z690E
Memory: G.Skill DDR5 32gb
Storage: 2TB 980 PRO
GPU: RTX 3080ti
Power Supply: Seasonic Prime TX-1000W
Case: Fractal Torrent
So, my machine has a few problems that might be linked to a deeper root cause. The main concerns are related to the motherboard. If the computer loses power (like being unplugged), it won’t boot until I reset the BIOS. It requires holding the BIOS reset button on the motherboard and pressing F1 to enter BIOS. This is quite frustrating because resetting the PC erases all settings.
The computer will randomly display a blue screen, with the address or highlighted file showing ntoskrnl.exe. It also bluescreens when I leave the PC locked instead of turning it off. I’ve noticed that the most frequent way to trigger a BSOD is by locking my PC. Although it doesn’t happen every time, around 15-20% of the time a lock leads to a BSOD. Usually, I only notice it when everything suddenly loads unexpectedly after logging in, compared to when I actually log back in.
Any attempt to overclock the memory to reach the advertised 6000 MHz results in constant blue screens or boot failures.
Occasionally, red blinking lights appear on my GPU, which I think indicates insufficient power supply. However, this seems to happen sometimes when I shut down the system. I had a previous 3080ti that failed unexpectedly, received an RMA, and the new one has this problem more often. I’m not sure if my old unit had this issue since it died early.
If I connect my DAC/AMP headphones via S/PDIF to the motherboard, the audio cuts every five seconds. Honestly, I’m not certain if this is related, but it’s quite bothersome. Any solution for this would be greatly appreciated. I use a FIIO K5 PRO.
Anyone have an idea about what might be causing all these issues? I’ve shifted my thinking from memory problems to power concerns until I ran memtest86 and got perfect results, then considered a power issue—though it’s not the only possibility. This makes me lean toward a motherboard-related problem?
Are the latest audio drivers, chipset drivers, and BIOS installed on your motherboard?
OP, performing memtest86 and passing all tests doesn't ensure stability when under load in Windows. It's also important to use the built-in Windows memory diagnostic tool and verify the results after rebooting. However, even after using the built-in utility, it's not certain that the system RAM remains stable during tasks like benchmarking or gaming, especially on AM5 platforms. I've noticed this issue with third-party tools such as memtestpro or Prime95, which should be run for several hours to confirm no errors appear, particularly with 32GB capacity. Additionally, check if your RAM is listed in the support documentation for your motherboard—there may be specific details about the G.Skill model you're using.
