I've been facing this issue since yesterday, whenever I put the computer into sleep mode and when I wake up, it takes me to boot menu with choices; start Windows normally, safe mode, etc. in short, it shuts down unexpectedly while waking up. I have my laptop dual booted with up-to-date Windows 7 SP1 (32-bit) and Ubuntu 10.10. This problem is not happening with Ubuntu.

I googled the issue and went through this, this and this page. But, none of the threads were helpful to solve it. I've found that there's something to do with device drivers. What can be done to resolve the issue? Can SFC utility solve it if it is due to corrupt system files?

do you have hybrid sleep on?-advanced power options->sleep->hybrid sleep to 'off'. – mic84 Sep 30 '11 at 11:28
@mic84: No, its just a normal sleep mode. – Kushal Sep 30 '11 at 18:28
I recall I saw a hotfix for this somewhere... – Bigbio2002 Jan 16 '13 at 19:21
It sucks having a Windows box when this sort of problem occurs. – Daniel R Hicks Apr 20 '13 at 20:54
(You might want to check Task Scheduler for any tasks that run "on unlock" or some such.) – Daniel R Hicks Apr 20 '13 at 20:58

There are many out there with the same or close to the same problem, this is what i found, should you wish to try.(i could not find any new Microsoft hotfixes for this problem)

  • Have you installed any software that may have changed your settings?
  • Does anything show in reliability monitor?
  • Are there any errors or warnings in the Event Log?
  • Have you tried disabling hybrid sleep in Advanced Power Options?
  • Is it possible that your computer is set to hibernate after a certain amount of time?
  • Have you tried turning off hibernate?
  • Are there any updates to your BIOS firmware?
  • Uninstall any third-party antivirus/firewall software
  • If you're overclocking, reset values to normal
  • Go to manufactures website and download and install all drivers from there
  • Run the Memory Diagnostic & HD Diagnostic,
  • Run System File Checker:
    • Start > Run > CMD > Right Click and Run as administrator
    • Type in SFC /SCANNOW
  • Run startup repair
  • Run a system image restore
  • Run a system restore, this will change your registry back to how it was before.
  • Reinstall Windows

I had fun reading your list :) Run the Memory Diagnostic & HD Diagnostic +1 – Ярослав Рахматуллин Aug 6 '15 at 23:30

Your memory or permanent storage is behaving oddly, causing Windows' hibernate procedure to choke? Run the SFC utility after scanning your drive and memory for errors (use intuiton... how old is the computer?).



If you know that your box is not broken or dying; allocate more "swap". Increase the size of your "pagefile" to about (at least) 50% of your memory (again use intuiton much RAM does your box use while fully operational?).
