screen of death

• Power off, unplug. Reseat the SATA data and power cables to the C: and D: drives; try a different SATA port and/or a different SATA cable for the C: drive. If it’s a 3.5" HDD, use a different PSU power lead. If the BIOS clock/date keep resetting, replace the CR2032 battery.
• In BIOS, confirm the boot drive is detected every time and is first in the boot order.

• If you see Automatic Repair, choose Advanced options > Troubleshoot > Advanced options > Command Prompt. If you can’t reach that, boot from a Windows 10/11 USB installer, click “Repair your computer,” then open Command Prompt.

• Run these, one at a time. Let them finish; they can take hours on a large/aged drive.
  chkdsk C: /r
  chkdsk D: /r
• Quick SMART check:
  wmic diskdrive get model,status
  If Status is anything other than OK, or CHKDSK reports lots of bad sectors, stop here, back up what you can (see step 6), and plan to replace the drive. Continuing repairs on a dying disk risks total data loss.

• System files:
  sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
  dism /Image:C:\ /Cleanup-Image /RestoreHealth
• Boot records (Legacy BIOS):
  bootrec /fixmbr
  bootrec /scanos
  bootrec /rebuildbcd
• Boot records (UEFI). First find the EFI partition:
  diskpart
  list vol ← note the small FAT32 “EFI” volume letter or assign one, e.g. S:
  exit
  bcdboot C:\Windows /s S: /f UEFI
  Reboot and test.

• Try restoring registry hives from backups (if present):
  cd /d C:\Windows\System32\config
  md backup && copy . backup
  dir RegBack
  If the files in RegBack are non‑zero:
  copy RegBack*.* .
  (press A to overwrite all)
  Reboot.

• From the same Command Prompt you can copy important folders to an external drive:
  robocopy C:\Users\<yourname>\Desktop X:\Backup\Desktop /E
  Substitute X: with your external drive letter. Alternatively, use Notepad > File > Save As to open a file dialog and copy with the mouse.

• Test memory (from Advanced options choose Windows Memory Diagnostic, or run MemTest86 from a USB). Faulty RAM can also cause both stop codes.
• If SMART/CHKDSK show problems, replace the C: drive and reinstall Windows, or clone the old drive to a new one with Macrium Reflect; then run sfc/dism again.

• Windows version (10/11 and build), and whether C: and D: are HDDs or SSDs (exact models if you can).
• Does the C: drive always appear in BIOS after a cold boot?
• Do you have access to a second PC and a spare 8 GB USB stick to make Windows install media?

Guys, please help! I was moving a 55GB Steam folder from drive C to drive D. Then I got a blue screen of death with the error "KERNEL_DATA_INPAGE_ERROR" then I was thrown into the BIOS, and then I rebooted the computer 2-3 times and the system started again. Then my Steam update started, I clicked on the cross and my computer FROZEN. I wanted to turn it off through the power supply but it did not turn off and I had to unplug it. Then when I plugged it back in, another screen of death appeared with the error code "BAD_SYSTEM_CONFIG_INFO" then I rebooted the computer several times and it sent me to additional settings, there I pressed different buttons but nothing helped. Now when I start the computer I have automatic recovery all the time and then it throws either in BIOS or again in additional parameters. Please help what to do in such a situation? It takes a long time to take the computer to the service center, you have to drive across the whole city, tell me how to fix it at home please!
