Hello everyone, I recently assembled a new PC and a series of very perplexing issues presented when trying to install an operating system. Worse yet, the issues are intermittent and do not follow any pattern that has helped me resolve them or narrow down a specific cause beyond a general I/O fault with storage devices. First I will share the components list, then my observations about the behavior of system, then all troubleshooting and remediating actions I attempted.
Asus Prime Z590-A motherboard
Intel 11700k CPU
Corsair Vengeance DDR4 RAM 16Gb x2 (3600)
Corsair RM850x 850 watt PSU
Samsung EVO 870 SSD x3
Seagate Barracuda 7200RPM HDD
Cooler Master 360mm AIO
Gigabyte Rx 6900xt GPU
140mm case fans x6
Once assembled I had no issues starting the system and reaching the BIOS, where I saw all drives listed. I was also able to connect a USB boot device after the initial startup and install an operating system (windows 10). The second startup is where I noticed the first irregularity, one of the SSD drives was no longer listed in the BIOS. I began the installation of the OS and once finished I checked to see if all drives were present, they were not. From this point on the BIOS would sometimes detect all drives, sometimes no drives, and everything in-between changing whenever I cycled power. Sometimes it will fail to output video, and this has occurred with the GPU removed. I have changed SATA ports, swapped cables, and still couldn't determine how to correct the issue with certainty.
The system will POST with no drives connected, and even seems to work fine with just the HDD connected, but as soon as an SSD or USB drive is connected it is a roll of the dice whether it will start up, whether I can access the BIOS, and whether it will even output video. The RAM and CPU seem to be fine, I triple checked to make sure there is sufficient power, the motherboard works fine with no drives connected, and it's extremely unlikely that all 3 SSDs are faulty. This is especially true considering I know my USB drive is fine and that will prevent the system from starting up properly sometimes. It seems to be the motherboard but I can't be sure. The faults change each time power is cycled as well.
To attempt to resolve the issues I have swapped SATA ports and cables, tried each drive individually with all others disconnected, I have removed the GPU entirely to see if it was a power or compatibility issue, cycled power many times, tested the CPU, updated the BIOS and SATA firmware, and still the results were as described above.
Any help will be appreciated, even a simple "it's the motherboard dummy" will help a lot in moving forward as I am incredibly frustrated with this and unsure what to do. Thanks.
