Hi,
Even running Intel diagnostics doesn't confirm whether you have the problem or not. The Intel microcode failure can occur intermittently and randomly, but the damage is permanent. The biggest problem with this failure is that it's not possible to directly identify it.
I recommend updating the BIOS and chipset drivers.
Remember that updating the BIOS is recommended, but it presents risks. If you interrupt the process, your laptop may not boot. Therefore, if you don't have experience with hardware and software, I recommend skipping this step, although it is highly recommended.
To update the BIOS, you first need to disable BitLocker. To do this, open the command prompt (as administrator) and run the command: manage-bde -off C:, wait for the decryption process, and restart your computer.
After that, you can download the BIOS from the link below:

After updating the BIOS, you will need to install these drivers:

Realtek HD Audio Driver
Intel INF installation
Intel Management Engine Firmware
Intel HID Event Filter
Intel Serial I/O driver
Intel® Dynamic Tuning Technology (APO) Driver
Intel® GNA Scoring Accelerator
Open the command prompt (Administrator) and run the commands: sfc /scannow and dism /online /cleanup-image /restorehealth. Wait for the process to complete and restart your computer.
Then, perform a clean boot and, if suggested, uninstall any applications you don't use.

Run a 24-hour test to verify that everything works correctly.
Although it's possible the SSD might be faulty.
