There may be a compatibility issue between your SSD and the platform. Please follow the steps below to troubleshoot (listed in order of likelihood):
1. Check if your PCIe SSD is running the latest firmware version. If not, update it to latest version using SSD Scope.
2. Please also make sure your platform BIOS is up-to-date.
3. For Windows OS, we suggest any version later than 1709. (Check your OS version in Settings -> System -> About)
4. Download and install the latest driver for all devices (e.g. chipset, power management, display card, etc.) used on the platform from their official websites.
