In any other application or game, the 4 USB 2.0 AMD ports work without any problems. However, as soon as I launch valorant game, they become unusable within a minute. No device is plugged in. I contacted MSI, the brand I'm using, and they gave me an unreleased BIOS version not on their website. This prevented major freezes after a similar problem I experienced before. Currently, I don't have any freezes with this BIOS version. Previously, when I launched a game, I had this problem, and a lot of TPM errors appeared in the Windows Event Viewer. The TPM errors were fixed, but all 4 USB 2.0 ports are completely disabled. Restarting the computer fixes it, but as soon as I launch Valorant, it freezes again. Dump files related to the error are created. How can I solve this problem? Device Manager error code 43. Drivers are update. Chipset is installed. The latest BIOS version is installed, and as I mentioned before, they shared a custom BIOS version with me that fixed the TPM issues, but the USB 2.0 port is still causing problems. This problem is triggered by SATA! I don't have any SATA drives connected to my computer. Initially, SATA connection completely disconnects (you can check this using the error code "error 45"). Then, simultaneously, four USB 2.0 ports become unusable. This causes excessive delay and synchronization issues in the other ports I use, both in games and during general computer use. When typing, the letters stutter, sometimes speeding up, sometimes slowing down and stopping...My computer was generally much worse before new BIOS update, because I frequently experienced TPM errors related to security. They fixed this problem with the new BIOS update, but there are still significant issues. I contacted MSI, and if they don't provide a problem-free solution, I will send the product back under warranty and I will not consider buying another MSI motherboard. I've been struggling with these problems for 4 months. I'm sharing a video related to these serious problems; what can I do?

If it only happens in Valorant, maybe there is something in their software causing issues. Do they use some kind of Kernel-level anti-cheat software? When you exit the game do the ports behave normally or do you need a reboot to fix them?

Yes, Vanguard has strict anti-cheat measures. This happens every time I play Valorant. USB ports work fine when I'm not playing Valorant, but SATA connection always disappears within 10 minutes of a computer reset, meaning it completely disconnects. Because of this, I was automatically banned from Valorant two weeks ago for "missing game files." I don't have a SATA drive, but my NVMe SSDs also disconnect momentarily, even though there's no error with them. My computer freezes completely momentarily, and then micro-stutters and delays continue until I reset it again.

If the board had been purchased for 4 months, it's not like you can return it. And we have to ask if you try different M.2 slot or SATA port...but just like dvair said, if only happens with valorant, then MSI might not be the only one that has problem :cry:

However, there's a catch. Valorant isn't to blame. The problem initially appears in the SATA hardware, and Valorant isn't the one causing the SATA hardware to completely disappear from the device manager. Sometimes, even when I'm not playing Valorant, the SATA hardware disappears. Therefore, Vanguard is a game that requires DMA protection, meaning it constantly monitors your hardware. During this monitoring, I think everything happens faster; when a SATA device, or any hardware device, appears, Vanguard might think I'm using a hardware cheat. I'm not making this up because Valorant automatically banned me eight times for a specific reason (item 7). They're aware of the hardware crash; they don't normally provide information about these things, but I sent them a video, and when they saw the situation, they realized I wasn't cheating and informed me, saying, "Your files are missing." When the SATA hardware disconnects, the NVMe SSD disks also disconnect momentarily, meaning it breaks its connection with Vanguard, which can make it seem like I'm cheating. Also, there was a TPM issue before, which was a bigger problem. MSI accepted this situation, that is, they are aware that there is a general problem with this motherboard, they solved the TPM problems with the new BIOS version, but the SATA and USB hardware problem still persists. I don't use any SATA SSD or SATA HDD drives. Despite this, the SATA hardware keeps disconnecting and causing other problems. The biggest of these is that the USB ports become unusable. This indicates a southbridge problem on the motherboard, and I think it's related to the BIOS. I observed this after formatting my computer for the first time. Two SATA hardware components communicate with Windows via the PCI bus, lines 12 and 9. After this hardware crash starts, the PCI bus numbers change. This is why the PCI bus numbers change in NVMe Express hardware.

I've observed this situation. Because when the SATA connection fails, besides locking my USB ports and rendering them unusable, there are significant disconnections involving NVMe Express drives initially, and this could actually be the reason for the constant micro-freezes. After I first formatted my computer, the PCI bus numbers for the SATA hardware were 12 and 9. Later, these numbers changed. I will send you screenshots showing the change in PCI bus numbers after the initial format and after I experienced the problem. 1. screenshot was taken immediately after formatting. As you can see, PCI bus numbers are for SATA hardware, numbers 12 and 9, but if you look at 2. screenshot, you can see that these numbers have changed.

Try installing the Asmedia SATA Driver 3.3.5.0000 2025-07-16, (from the drivers & downloads support page). With latest bios I have noticed an occasional storahci event id 129 error with the generic Microsoft sata drivers.

I downloaded and installed AsMedia SATA driver. Nothing changed. Problem persists.

I've been researching the SATA and USB problem you mention on reddit, but I can't find any evidence of general problems affecting SATA. USB dropouts there are a few comments about problems with USB when using 3rd party monitoring. I use HWinfo (and NZXT cam); both poll my USB connected NZXT Krakon AIO. Other USB connected devices I use - keyboard & mouse, I have a blu ray drive, scanner, lifecam and external hard disk connected via USB caddie.

I'm not seeing any issues apart from the storahci event id 129 error, which I was able to resolve:

Good luck with finding a solution...

I tried installing the AsMedia firmware, but it gave a warning because it was the same version and wouldn't install. Then SATA completely disappeared :) So the firmware (Brick Mode) failed. Now the SATA IDs don't show up with AsMedia Tool. As expected, I installed 7E62v1A4D and my game ran perfectly smoothly, including the initial lag. After this BIOS version, AGESA 1.3.0.0 updates came out. So these are probably patches for the xx.1A4D BIOS version, some kind of BETA version. Moreover, the unreleased BIOS version they sent me was also like that. From what I've researched, MSI seems to be experimenting on users using their BIOS software due to problems they're having with their root access. I don't know what's wrong with my root access right now, but it's definitely related to the BIOS. I will use the money I get to get it back under warranty as soon as possible and exercise my rights. Because I don't plan on buying MSI again. For now, SATA isn't important to me; the USB 2.0 ports just stop working after playing Valorant. I think I'll return it and get a Gigabyte one. I don't want to recommend any MSI products after this. About 80% of the threads opened by users experiencing these kinds of hardware conflicts are from MSI users. MSI is lacking in BIOS, and even with the latest BIOS versions, these problems are triggered, and can even lead to hardware bricking. My final decision is never to buy an MSI motherboard again. Thank you, the thread can be locked. Everything is great with the old BIOS version now, the USB noises have stopped, and the freezes have gone away, after the SATA chip bricked. Thanks MSI :) I apologize for my limited English and lengthy explanations. Thank you everyone.
