Windows 7: Windows 7 screen flickers horizontal lines randomly

Windows 7 screen flickers horizontal lines randomly

I have a windows 7 32 bit. Acer Aspire 5920G.

The screen started flickering about a week ago. It happens randomly. When I use my browser, open documents, run programs or even while on desktop.

I have already looked around on youtube, google and on the forum here. I've tried to change the screen resolution, change text size and adjust the screen refresh rate but it is automatically on 60 hertz and has not other options. None of these options helped.

I have not downloaded any programs recently, meaning I do not think it's because of a software added. I did run CCleaner, Bitdefender antivirus and a spyware/malware check, but to no avail.

It flickers as soon as I adjust the screen manually.

Let me know if I have posted on the wrong thread.

Thanks

Have you tried updating/reinstalling your drivers?

@ indianacarnie

Yes, I believe I did that. I ran updates on Bitdefender update, Windows update, NVIDIA update and I even went to Intel driver update and ran the scan they have there.

I might have missed something though as I'm not IT literate, is there anyway I should check to see if all drivers are updated?

Click on your Start Button and type in Device Drivers and hit enter. This will open your Device Drivers. If you see any Exclamation Marks, there is a problem and the Driver needs to be updated.

The only one that had an exclamation mark was Teredo Tunneling Pseudo-Interface under Network adapters.

I tried to update it, it said it was already up to date. I disabled it and enabled it, but it still had the exclamation mark.

There could be another problem with it besides not being updated. Read this link and do what it says to find out the problem. If it doesn't do anything, check back.

Visit the following link for information regarding Teredo Tunneling Pseudo;

The flickering screen may be related to the refresh rate. Check the monitor manufacturer for the correct setting and then verify it is set properly.

@bigmck I followed the steps on the link you sent, and it seems the driver had a code 10 error. I followed the instructions for how to fix the error and did a reboot. That did not help and I might follow the other steps provided on that link as well, but it seems like you lot agree on Sir Georges suggestion so I'll give that a try and report back. Thanks.

Step 7 on the pdf file provided by Sir George is to Right click on “6to4 Adapter” and select “Disable”. I dont see a 6to4 Adapter.
