Screen flickering and horizontal lines when coming out of standby on Windows 8

I upgraded my Dell Latitude E6510 with an Nvidia NVS 3100M  to Windows 8 a short time ago, and noticed something fairly quickly: Whenever my display came back on after being powered off from power saving mode, or the laptop came out of sleep mode, the screen had a very noticeable flickering and some distinct horizontal lines. The best way to explain it was to say that there was something very wrong with the display refresh rate.

The effect would gradually diminish with time, but wouldn’t completely go away. I updated the graphics drivers from the built-in Windows 8 drivers to the latest ODE graphics driver for Windows 8 64-bit (310.90) — that didn’t fix it. I also noticed that putting the display in 40hz mode and then back in 60hz mode didn’t fix it either. I even would have the problem if I shut down completely and powered the laptop back on a few moments later.

I later found this blog post from someone having the exact same issue. He even indicated that he’s had hardware replaced on his notebook, and that didn’t fix the issue. He did, however, find a fix: Dell’s A08 drivers for the NVS 3100M graphics chipset. He posted links to a Dell search for A08 drivers and two drivers that specifically worked:

nVidia Quadro FX 880M – Win7/Vista 32-bit Graphics Driver

nVidia NVS 3100M – Win7/Vista 64-bit Graphics Driver (this is the one I used)

So I uninstalled my existing Nvidia drivers and installed the 64-bit driver linked to above. You know what? It worked. The flickering went away immediately, and it continues to work correctly resuming from standby.

I also recall speaking to someone who had a similar issue, albeit on Windows 7. I’m guessing it was probably related to the drivers as well.

UPDATE: After doing some more testing, I found this: I took a clean install of Windows 8 where the screen flickering was there, reformatted and reinstalled Windows 7 64-bit. After booting into Windows 7, the screen flickering was still there! It would seem that the driver is manipulating the graphics controller to produce this flicker. Installing Dell’s recommended NVS3100M driver for Windows 7 did fix the flickering issue.

Performing a clean install from a Windows 8 upgrade media

If you purchased the Windows 8 upgrade from Windows 7, but would rather do a clean install, here’s a method that I’ve found that has been reported to work.

First, obviously, delete all partitions during the Windows install, supplying your key when requested.

After Windows 8 installs, and if Windows won’t activate, do the following:

Run regedit, and set:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Setup\OOBE\MediaBootInstall to 0 (zero)

Open an administrator-level command prompt, and run the following:

slmgr /rearm

Then reboot and run activation again.

Windows 8 error code 0x807800C5 during Windows 7 File Recovery backup

The following error appears if you try to include a system image in your backup using the Windows 7 File Recovery backup tool.


There was a failure in preparing the backup image of one of the volumes in the backup set.

Details: The mounted backup volume is inaccessible. Please retry the operation.

Error code: 0x807800C5

According to this forum

For Win 8 only: The Win 7 back up program included with win 8 does not support backing up a image file to any kind of NAS device (UNIX, Linux) . Internally the program gives an error that the NAS device has an incompatible sector mapping type. You can backup to a hard drive that is attached to a different windows machine and then back up that file to your NAS. Convoluted, but it works.

So, backing up a system image to a Samba share is out of the question. To work around this, disable the creation of a system image in your backup.

I haven’t tried backing up to an NTFS-formatted iSCSI LUN, which might work. If anyone has tried that, I’d be interested to know the results.
