After upgrading the CPU, the primary M.2 slot isn't displaying the drive.
Hey everyone, I have an X570 AORUS ELITE (rev. 1.0) motherboard that I used with 3600x / F3 BIOS for years. My goal was to upgrade to a 5800x3d, which I just got on sale. To prepare, I updated the BIOS to F37 and everything worked for about three weeks running my 3600x. This weekend I replaced the 3600x with the 5800x3d. After booting up, I saw the fTPM message but no boot device was detected. I checked the bios again—no devices listed in the main M.2 slot, though other drives were fine. I swapped back to the 3600x and got the same issue. The new M.2 card fits in the enclosure, but it still doesn’t appear in the BIOS or when installing Windows. I’ve double-checked the part picker; it says my motherboard is compatible with the new drive. I’m confused—could this be because both CPUs were damaged? Is the slot now faulty, or am I hitting a storage interface limit? I’m currently installing fresh Windows 10 on an old 2.5 SSD for remote work via AM. Any advice?
You can test the CMOS voltage by using a multimeter or checking the motherboard manual. Since your CPUs didn’t show bent pins and there’s no resistance when installed, it might indicate a power or connection issue. Regarding BIOS, downgrading isn’t necessary if everything functioned with your 3600x for a short time—just confirm the settings in your system settings. The M.2 slot should be under the BIOS configuration menu; look for storage options there. Your other M.2 slot still showing up suggests it might be a hardware or driver problem rather than a BIOS issue.
Just touch the battery lightly if it gives you a shock—it’s fine! 🤓 This is the classic method for removing test button batteries without needing a voltmeter! Old-school tip!
I reset the CMOS and chose the default settings, but it didn’t work. I’ve been using the newest BIOS for a few weeks before replacing the CPUs.
