Good day all, I am going to go into as much detail as I feel I can give. That way someone hopefully wont ask me if I tried something I already tried.

So, here it goes...

Today, the wife restarted her computer. She says it was doing some AVG update. When it rebooted, there was sound.. you can hear the Windows logo screen sound and a sound from one of her programs that tries to load every time she restarts her computer. From this, I can deduce that her computer is functioning properly. And this is where the problem begins...

Because her monitor says it's in standby mode after the Windows logo screen cycles.

I've tried different cables and I've swapped out monitors with one I'm using to type this message with on a different computer. It acts the same. I've also tried a different (known good) graphics card and also different slots on the motherboard.

I've attempted (when stupid Windows 10 allows me too) to try and boot in selected modes.. I've tried the one where it's supposed to load into low resolution. I've tried safe mode... and in both of these cases, the monitor(s) stay powered up, but their screens are black, which forces me to perform a hard restart.

I've tried unplugging the monitor and pushing and holding the power button for 1 minute (something I read online) and I've tried to same with the computer. I've also pulled the battery out of the computer for a good 3 minutes and still everything acts the same.

I can hear the computer booting up, but can't see anything..

Please help guide me through what could be wrong here and what my next steps are for troubleshooting.

Peace, Defender

You stated that you attempted to try and boot to selected modes.
Does this mean that you can see the display?


If that's the case, then try these repair/recovery steps:


NOTE:  Try a clean boot to see if the problem clears up that way:  http://www.thewindowsclub.com/what-is-clean-boot-state-in-windows
If it does, then different troubleshooting steps are called for.

Here's some repair/recovery/restore options (in this order):

1 - Startup Repair.  Run it 3 times, rebooting in between tries.

2 - System Restore to a point before this started happening.

3 - DISM/SFC repair (DISM doesn't work with W7, although SFC does)  - doesn't work if you're not able to boot to Windows (if that's the case, the offline DISM repair is listed in the next quote box below this)

Then please run the following DISM commands to see if there's any problems with the system (from an elevated (Run as administrator) Command Prompt).  Press Enter after typing it:
Dism /Online /Cleanup-Image /RestoreHealth

    FYI - I have repaired systems using the last command even though problems weren't found with the first 2 - so I suggest running them all.

    From this article: http://technet.microsoft.com/en-us/library/hh824869.aspx

    You can also run sfc.exe /scannow from an elevated (Run as administrator) Command Prompt to check for further corruption. Include the CBS log (located at C:\Windows\Logs\CBS\CBS.log) if you'd like to have a Windows Update expert check it (I don't check them because I can't read them)

4 - RESET using the "Keep My Files" option (W8 calls this a REFRESH; W7 and earlier doesn't have this function)

5 - Repair install of the OS (Thanks to FreeBooter!):

"How To Perform a Repair Installation For Windows 8, 8.1 and 10"

    "How to Do a Repair Install to Fix Windows 7"

    "How To Perform a Repair Installation For Vista"

    "Non-destructive reinstall of Windows XP"

6 - RESET using the "Remove Everything" option (W8 calls this a RESET; W7 and earlier doesn't have this function)

If using W7 or earlier, this can be accomplished by resetting the system by use of the recovery partition/recovery disks/recovery drive.
If you don't have them, you can usually order them from the OEM manufacturer of your system ( US points of contact here:  http://www.carrona.org/recdisc.html )

7 - Wipe and reinstall from the Recovery Partition (if so equipped)

8 - Wipe and reinstall from Recovery Media - to include deleting all partitions.
If you don't have them, you can usually order them from the OEM manufacturer of your system ( US points of contact here:  http://www.carrona.org/recdisc.html )


Offline DISM repair:


DISM /Online should only be used when running from within Windows. Run this command instead:

Dism /Image:C:\ /Cleanup-Image /RestoreHealth

Did you also try doing SFC scan while booting off of Recovery Environment or Install Disk? In those cases, the commands are slightly different:
sfc.exe /scannow /offbootdir=c:\ /offwindir=c:\windows

Well, I reluctantly performed a reinstall (keeping all personal files) and low and behold, the freakin' thing works again. This might just be the weirdest Windows problem I've ever ran across. I would love to know what would make it act that that.. Oh well, it's fixed now. 


Thanks, Defender
