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 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.

- Windows 8 laptop connected to power cord, screen flickers
Anyone else having the same issue? Have the drivers above worked for you? Please feel free to share your experience in the comments below.
A reader (M.R.) contacted me asking about running Symform on his Synology DS3611xs. He later uninstalled it and found that the SymformContribution folder was getting recreated at every reboot.
After a number of email exchanges, he was able to get Symform to confirm it was a bug:
Thank you for contacting Symform support. I understand that you are having an issue with the SymformContribution folder being re-created after you have un-installed Symform, and rebooted the DiskStation.
I have been able to reproduce this issue, and found that it is re-created due to the folder listed as a Shared folder in the Synology Shares section.
I have sumbitted an internal bug ticket to my developers to look into this issue. From what I found, it is just re-creating the folder, and the Symform services are not present, or running.
The commands to fix it follow, but I’ve updated step 3 to an absolute path:
1. Here is the command to view the Synology shares table:
/usr/syno/sbin/synoshare --enum ALL
2. If you see the SymformContribution folder listed, enter in the following command:
/usr/syno/sbin/synoshare --del TRUE SymformContribution
3. Then, to remove the folder from the Volume1 folder, enter in the following:
rm -rf /volume1/SymformContribution
Adjust the path in step 3 if your contribution folder is on another volume.
Thanks again to M.R. for the information and legwork getting this resolved!
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:
Then reboot and run activation again.
