New PC model (excluding PSU and GPU) stops when fTPM reset is denied, then won't turn on.
New PC model (excluding PSU and GPU) stops when fTPM reset is denied, then won't turn on.
MB: Asus B650M-E Wifi
CPU: 7 7700X
RAM: G.Skill Aegis 5 32GB (2x16GB) 6000MHz DDR5 (F5-6000J3636F16GX2-IS)
PSU: Antec EAG Pro 650W Gold+
AIO: Frozen Prism 360
GPU: 1660Ti
Context: The CPU and RAM passed testing at Scorptec. During boot, the "reset fTPM?" screen repeatedly appeared, which I ignored each time since I didn’t use Bitlocker encryption.
PC suddenly stopped working during operation (second day). It wouldn’t power back on even after using a screwdriver to reset PwSw pins. After being away for three days, it started up again! However, it shut down within 3-5 seconds after the fTPM reset was rejected. No response when trying to power it on.
Four days later, I managed to boot completely. I set the BIOS to default settings, made no changes, and opened Windows for half a day. After waking up, the PC crashed during sleep.
No response when attempting to power it on.
After waiting four days, it finally booted fully. I adjusted the BIOS to optimised defaults, checked all power and sleep configurations (such as max performance plan, no sleep/hibernate), ran "DISM.exe /Online /Cleanup-image /Restorehealth" and "sfc /scannow", installed Windows updates, and restarted. Again, the PC shut down 3-5 seconds after rejecting the fTPM reset and refused to power on.
Tried all these steps while disconnecting the PSU and peripherals:
- Placing one stick in each slot sequentially, pausing 5-10 minutes between attempts for memory training
- Holding the power button for one minute
- Re-seating the CPU and checking for bent pins
- Applying thermal paste again
- Reconnecting the MB power plug and GPU
- Performing a BIOS flashback using the MB manual instructions in the BIOS port
- Reseating the CMOS battery
I’m puzzled by why the PC only powers off after rejecting the fTPM reset—does that indicate a software problem? But since it still fails to start afterward, it points to a power issue.
Anyone with similar experiences would be very helpful. I’m seeking advice on how to resolve this long-term problem.
If you're not using encryption, you might instruct it to accept the ftpm change and observe its behavior. TPM is intended as a trusted platform module for security purposes. Ftpm is an AMD TPM module. Therefore, the computer may shut down because it perceives an issue with security.
Solution: I checked my PSU using a testing device and found it to be faulty. I purchased an 850W PSU and everything continues to work after navigating the ftpm page! Even though I'm still puzzled about why it keeps displaying ftpm during boot, I decided it wasn't worth the trouble to press a single key, so I've been tolerating it.
