Laptop won't boot, unusable

post #1 of 4
Thread Starter 
So I have a rather bad looking problem on my hands. I left my laptop on sleep overnight but the next morning I found it had turned off, when I boot normally the PC stays on "windows starting" loading screen for ever, it doesn't load or anything just sits there. I left it on sleep on battery power only but there was still juice in it the next morning. I tried last good configuaration and it got past that but it loaded just a blank screen with a cursor, mouse responds but keyboard does nothing, after about 30 minutes it flashes a very brief BSOD got about 0.1 seconds and shuts off. It never reached the login screen, exact same thing happens in safemode but it will just sit there indefinitely as there is no BSOD. Repair windows loads but it can't fix the problem. I don't have a repair system restore point (yes I'm dumb) and I don't have a windows disk to try fix it but I'll see if a friend does.

So stuffed, I need to submit a resume by Wednesday, also I don't have access to my desktop so diagnostics will be hard, anyway, what should I do? I have tried almost every single option on the boot menu and nothing works. any fixes or should I just throw in the towel and reinstall windows? (I'd rather not do that if I can avoid it) There's also some data on there that hasn't been backed up lately too. I'm also hoping my friend will let me plug my laptop hdd in to copy that stuff off it too

I have read a few articles online that say it is a problem with windows shell.exe in the registry but how can I even fix that if I can't boot it to open regedit? Any expert advice?

    If you have already tried all the options on the boot menu (ones like Last Known Good Configuration and Safe Mode) and Startup Repair can't repair the problem, there are two things left to try before reinstalling Windows:

  1. Copying important (or time sensitive files) to a USB stick to save them or use them on another computer.
  2. Manually restoring a registry backup to see if that fixes the problem.

    However, to do either of them, you'll need a Windows Vista/7/8/10 installation or repair disc (a functioning computer can make a repair disc if you don't have a Windows installation disc).

  1. Turn the laptop on, and quickly insert a Windows installation or system repair disc.
  2. If the laptop ignores the disc and attempts to boot normally, you may need to find the shortcut key for the BIOS's boot menu (I would start by trying [F11]), or change the boot order in the BIOS.
  3. If the disc successfully loads, you should see a prompt "Press any key to boot from CD or DVD...".  Go ahead and hit the spacebar.
  4. Upon successfully booting from the disc, it will ask for your language.
  5. After clicking [Next], you will see a big "Install now >" button.  Ignore it, and click "Repair your computer" instead.
  6. Setup will look for a compatible operating system.  If it finds one, click [Next] and skip to step #9.
  7. Click the Restore your computer using a system image you created earlier option, and click [Next].
  8. When the wizard appears asking you where the backup image is located, simply close it.
     
  9. You should now be at the System Recovery Options dialog with a list of tools.
  10. Click Command Prompt, type "regedit", and press [Enter].
  11. Registry Editor should open.  We don't need Registry Editor, but rather an Explorer window.  We are going to use Registry Editor's export function to bring up a save dialog that we will use as an Explorer window.
  12. Click File -> Export....
  13. In the export dialog, change Save as type to All Files.
  14. Click the drive dropdown at the top and select your laptop's system drive.  It may or may not be C:\.
     
  15. The first thing I would do is copy your most important (and not backed up) files to a USB stick.  You can do so from the dialog you just opened.  Just treat it as an Explorer window, and you should be able to copy files/folders to a USB stick with no problem.
  16. When you're done copying important files/folders, click the drive dropdown at the top, and note the drive letter that was assigned to your laptop's HDD (probably C:).
  17. Click [Cancel] on the Export dialog and close Registry Editor.
     
  18. Back at the Command Prompt, type "chkdsk C: /f /r /v /x" (replacing C: with the correct drive letter if need be), and press [Enter].
  19. This scan may take a while, but it shouldn't take more than a couple hours.  If it appears to hang (progress not moving forward), the problem may be a failing HDD, and I recommend aborting the operation to prevent the HDD from failing altogether.
  20. When it is done scanning, read its summary to see if it corrected anything.  If it did, reboot your computer and see if it works now.  If not, repeat steps 1 - 14, and go to step 21.
     
  21. Navigate to Windows -> system32 -> config.
  22. You should see a bunch of files.  Rename "SYSTEM" to "SYSTEM.bad", and "SOFTWARE" to "SOFTWARE.bad".  Remember that you're doing these file operations from a Save dialog, which means that if you double-click a file, it will assume that you want to overwrite it.  If you do this by accident, simply click [No] when it asks for confirmation to overwrite, and you'll be returned to the Save dialog where you can continue working.
  23. Scroll back to the top of the list, and you should see a folder named RegBack.  Double-click it (Windows\system32\config\RegBack).
  24. Inside, you should see a list of files similar to the ones you were just working with.  Select SYSTEM and SOFTWARE, and press [Ctrl]+[C] to copy them.
  25. Navigate back (up) to the config folder, and press [Ctrl]+[V] to paste the backups into the config folder.  When you're done, you should see the old registry files that you renamed (SYSTEM.bad and SOFTWARE.bad) beside the files you just copied from the RegBack folder.
  26. Click [Cancel] on Registry Editor's Export dialog, and close Registry Editor.
  27. Close the Command Prompt and click [Restart].

    If your laptop still doesn't work after this, you'll probably just have to reinstall Windows!

I didn't read all the way through techie's post (looks very complete though, I'd read and do that before my advise...) but personally I would go the nearest PC parts store and buy the cheapest laptop drive they have (a USB enclosed one if you don't already have an enclosure) and use something like clonezilla to clone the drive over (still need a way of making the clonezilla CD but after that it's all CD-based so it should be good). If you have to submit a resume soon that should probably be the priority so I would say just get a working copy of windows separate from that drive (you didn't say if you have to write a resume from scratch or merely retrieve an existing one for editing/printing). Once your drive is cloned to the USB put the drive from the USB enclosure in your latop and the one in the laptop in the enclosure. If the new hard drive boots windows then good, if not you might have to use a 90/180 day trial windows 7 or 8 (or beta win 10?) to install on your fresh new hard drive. Maybe not ideal but theoretically you would have access to your data and a temporary working system.

Could be there's a bad sector on that drive, you might try scandisk or possibly something much beefier/more powerful that the windows scandisk. Maybe not very likely but not impossible. Okay maybe Techie covered that.
