My Lenovo IdeaPad Gaming 3 running Windows 11 has started crashing shortly after a recent update. It stays powered on in the BIOS, and the RAM appears to be fine, but Windows usually runs for only a minute or two before shutting down. File Explorer and file-copy operations make it crash even faster. The system drive is a 512GB Samsung PM9C1a NVMe SSD, which we believe is soldered into the laptop and cannot easily be removed for external access. We were considering a clean Windows installation, but there are a few irreplaceable writing projects, notes, and worldbuilding files on the drive, including one manuscript that has no other surviving copy. BitLocker was disabled while troubleshooting a possible BIOS update, after which the instability seemed worse. Is there a safe way to access or copy the files before reinstalling Windows? We can still enter the BIOS, but we do not know whether the files can be recovered from there.

Do not perform a clean install or keep experimenting with BIOS settings yet. BIOS itself cannot browse or copy your Windows files. The safest approach is to boot from a Windows installer or Linux USB and copy the important files to another drive. If BitLocker is still involved, you will need the recovery key; disabling it may also have started a lengthy decryption process, which can make a failing or unstable system drive work much harder.
Before attempting file copying, create a full image of the SSD if possible. A recovery environment can use tools such as ddrescue or a disk-imaging utility to copy the drive to another disk, skipping damaged areas and allowing repeated attempts. Once the image exists, work on the copy rather than the original. Repeatedly booting Windows and dragging files through Explorer is riskier because it causes lots of reads and writes.
If you only have limited storage, copy the irreplaceable manuscript and project folders first rather than trying to repair the entire installation. Avoid chkdsk, resetting Windows, formatting, or turning BitLocker settings on and off until the data is secured.
Double-check the exact laptop model and motherboard layout. The PM9C1a is generally an M.2 NVMe drive, not a type of storage that is normally soldered directly to the board, although a particular laptop may use a different configuration. Do not open it or force anything, but verify the service manual or have a technician identify the drive. If it is removable, putting a replacement drive in the laptop and connecting the original through a suitable NVMe enclosure may be the simplest recovery route. You will still need the BitLocker recovery key if the volume is encrypted.
Since the machine remains stable in BIOS but crashes under Windows activity, possible causes include overheating, power delivery, storage failure, a bad update, or a Windows installation problem. Keep it cool and avoid unnecessary testing. Booting from a USB recovery environment is a reasonable low-cost first attempt, but if that also crashes or the drive reports errors, shut it down and use a reputable data-recovery service. Tell them the data is important and explicitly do not authorize formatting or reinstallation.
If the laptop crashes even when running from external recovery media, that points more toward a hardware or power problem than ordinary Windows corruption. In that case, stop trying to repair Windows and prioritize making a disk image or getting professional recovery help.
