When upgrading to a new CPU, users may encounter a rather alarming error message: “FTPM/PSP NV corrupted or FTPM/PSP NV structure changed.” This issue can confuse even experienced PC builders, as it is unexpected and can stop the system from functioning properly. Let’s dive deeper into what this error means, how it occurs, and the steps you can take to resolve it.
What is FTPM/PSP NV?
FTPM (Firmware Trusted Platform Module) and PSP (Platform Security Processor) are key security features embedded in modern CPUs, particularly from AMD. FTPM is a software-based implementation of the Trusted Platform Module (TPM), a hardware chip responsible for secure cryptographic operations on the system. PSP, on the other hand, is part of the AMD security architecture that helps manage these operations.
The error message ‘new cpu installed ftpm/psp nv corrupted or ftpm/psp nv structure changed’ indicates that the non-volatile (NV) storage associated with these security features has either been corrupted or altered. This may cause your system to freeze, reboot randomly, or fail to boot entirely after installing a new CPU.
Why Does This Error Happen?
This error usually appears during a CPU upgrade. The security keys stored in FTPM/PSP NV are linked to the old processor. When a new CPU is installed, these keys may no longer align with the system’s expectations, causing the “corrupted” or “structure changed” message to appear.
There are several key reasons for this issue:
- CPU Change: Upgrading or changing your CPU is the most common cause. Since the security modules are tied to specific hardware components, replacing the CPU can trigger this error.
- BIOS Updates or Resets: If you updated your BIOS or performed a reset while changing your CPU, the system might see this as a change in the security environment.
- Corrupted TPM Data: Sometimes, the TPM or PSP data gets corrupted for various reasons, including hardware faults or improper shutdowns, leading to the error.
Real-World Examples of the Problem
Users across online forums, like Reddit and Tom’s Hardware, have shared their frustrations with this issue. One user on a popular PC-building forum mentioned upgrading from a Ryzen 5 3600 to a Ryzen 7 5800X, only to be greeted by this error. They described how their system refused to boot and they were left wondering whether their CPU was faulty or something else was at play. Another user detailed how they received the same message after updating their BIOS, making it clear that this is not always directly related to the CPU but can stem from other changes in the system’s configuration.
The ‘new cpu installed ftpm/psp nv corrupted or ftpm/psp nv structure changed’ error isn’t hardware damage but more of a software configuration conflict. Fortunately, this means it can be resolved through proper troubleshooting.
How to Fix the FTPM/PSP NV Corruption Error
Now that we understand the nature of the problem, let’s go through the step-by-step process to fix it.
Step 1: Restart the System and Check BIOS Settings
The first and simplest step is to restart your computer and enter the BIOS/UEFI. Most modern motherboards have a shortcut, such as pressing F2 or Delete, to access the BIOS during boot. Once in the BIOS, check the following settings:
- Look for the TPM/FTPM or PSP setting in the security or advanced options section of the BIOS.
- If enabled, you may want to reset FTPM/PSP settings to see if it clears the error. On some boards, this will trigger a message asking if you want to clear the current keys. This is important because the current stored keys might be the ones causing the conflict.
Note: Clearing the FTPM will erase all stored security keys, including BitLocker keys, so make sure you back up important data before proceeding.
Step 2: Update the BIOS
If clearing the TPM doesn’t work, the issue might be due to an outdated BIOS. Manufacturers often release BIOS updates to improve compatibility with new hardware, including processors. Follow these steps:
- Check your motherboard manufacturer’s website for the latest BIOS updates.
- Download the update, and follow their specific instructions for installation (usually done through a tool within the BIOS itself).
- Restart your system after the update, and see if the error message persists.
Step 3: Reset BIOS to Default Settings
Another potential solution is resetting your BIOS to default settings. Sometimes, specific configurations might conflict with the new CPU’s security features. Here’s how to reset your BIOS:
- Restart your system and enter the BIOS.
- Look for the option to load default settings or optimized defaults.
- Save and exit the BIOS, allowing the system to reboot.
This will clear any custom configurations and might resolve the error.
Step 4: Clear CMOS
If updating the BIOS doesn’t resolve the issue, clearing the CMOS (Complementary Metal-Oxide Semiconductor) might help. The CMOS stores BIOS settings, and resetting it can often clear out stubborn conflicts. Here’s how:
- Turn off your computer and disconnect it from the power supply.
- Locate the CMOS battery on the motherboard (a small, round, silver battery).
- Carefully remove the battery for about 10 minutes, then reinsert it.
- Plug your computer back in and try to boot.
Clearing the CMOS resets the BIOS completely, which might eliminate the error related to FTPM or PSP NV corruption.
Step 5: Reinstall the Operating System
In rare cases, you might need to reinstall your operating system if the error persists. This is generally a last resort, as it involves more time and effort, but it can completely refresh the system and resolve any software conflicts caused by the CPU upgrade.
How to Prevent FTPM/PSP NV Errors in the Future
Once the issue is resolved, there are steps you can take to prevent similar problems when upgrading hardware in the future:
- Keep your BIOS updated: Regularly checking for BIOS updates and applying them can help avoid compatibility issues when upgrading hardware.
- Back up security keys: If you’re using BitLocker or other security measures, back up your keys to prevent data loss when resetting the TPM or PSP.
- Clear FTPM before a CPU upgrade: Some users have found that clearing the FTPM settings before installing a new CPU can prevent the error from appearing altogether. This is an optional but useful precaution.
- Handle hardware changes cautiously: Whether upgrading your CPU or changing other components, ensure that the system is properly powered down and that you follow best practices to avoid damaging sensitive components.
