Whenever I attempt startup, I receive this message:

We apologize for the inconvenience, but Windows did not start successfully. A recent hardware or software change might have caused this.

If your computer stopped responding, restarted unexpectedly, or was automatically shut down to protect your files and folders, choose Last Known Good Configuration to revert to the most recent settings that worked.

If a previous startup attempt was interrupted due to a power failure or because the Power or Reset button was pressed, or if you aren't sure what caused the problem, choose Start Windows Normally.

Seconds until Windows starts: 30

~~~
However my results from selecting any of the options results in freezing, where the countdown stops at its current value, and keyboard becomes non-responsive. If I allow the countdown to reach 0, it will freeze then instead.

Last time it was working correctly, when it was shut down, it did so remarkably 'quickly'.
Any help would be greatly appreciated. Preferably not resorting to formatting HD... I don't exactly have backups.
Thanks.

Brief summary and practical plan based on the thread: the machine is presenting the Windows recovery/boot choices and then becomes unresponsive when a selection is made or when the countdown reaches zero. later noted the problem “resolved” without explanation; reports the same symptom. The behaviour is exactly the sort of intermittent startup failure that often hides either an I/O problem (disk or driver), a keyboard/BIOS handoff problem, or filesystem corruption caused by an abrupt shutdown.

Common, non-destructive checks (fast, try these first)

  • Remove every non-essential peripheral (USB drives, printers, card readers, external HDDs) and try booting again.
  • Try a different keyboard port or a PS/2 keyboard; verify the keyboard works in BIOS/POST. If the keyboard works in BIOS but not at the Windows boot menu, enable “USB legacy/keyboard support” in BIOS or use a different USB port (use USB2.0 ports on older boards).
  • If the machine ever booted “very quickly” before the failure, treat that as a sign of an unclean shutdown — run disk checks next.

Recovery/diagnostic steps (ordered, non-destructive first)

  1. Boot from Windows install/repair media and use Startup Repair / System Restore.
  2. From the repair command prompt run filesystem and boot repairs:
chkdsk C: /f /r

For legacy XP Recovery Console:

chkdsk C: /p /r
fixmbr
fixboot
bootcfg /rebuild

For Vista/7/8/10/11 WinRE:

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows

Allow chkdsk to finish (can take hours on large drives). Be careful with fixmbr/bootrec if there are multiple OSes.

Further checks and precautions

  • Run a full memory test (MemTest86+) for several passes.
  • Check HDD SMART using the manufacturer's diagnostics or bootable tools; if SMART shows reallocated sectors, back up immediately.
  • If repair attempts fail, boot a Linux live USB to copy important data off before attempting reinstall or destructive fixes.
  • Even if the fault appears to clear (as with ), run the disk and memory checks and make a backup: intermittent fixes often precede permanent failure.

Never mind, problem resolved through unknown means.

HELP!!! I have this exact problem!!! Any ideas??? Please!!!!!
