Windows 8.1 Desktop Flickering

2015-04-23, 5:15 AM
After I rolled back to windows 8.1 from windows 10 technical preview, my windows 8.1 desktop flickering won't stop. Am I screwed? Also, my laptop is G510.

Hi Hohshua,

 

Welcome to the Forums    

    

As per the query we understood that you are facing issue  with flickering in your Lenovo G510 laptop.

 

Try to boot the system into safe mode and check for the issue, also uninstall the display driver and restart the system and check for the issue, later reinstall the driver and check.

 

Click here for the display driver.

 

Hope this helps. Do post back if the issue persists!                                                   

 

Best regards,                                                          

 

Ashwin. S

I'm still unsure about running it in safe mode after searching through the internet. BTW, my BIOS only has 3 options: Windows (Boot Manager), something about IPv4, and something about IPv6

I think I figured out how to run it in safe mode. But do I do Safe Mode, Safe Mode with Networking, or Safe Mode With Command Prompt?
Also, I can barely navigate through my desktop, so do I just run msconfig.exe from the Task Manager?

Re: Windows 8.1 Desktop Flickering

I have a G780 and screen flickers randomly.  Laptop almost 1 1/2 years old.  Flickering started with preinstalled Windows 8 so this is not a Windows 8.1 issue but a Lenovo computer problem.  Also bottom of screen above toolbar was 'shaded'.

 

I contacted support and they reset my computer to original state as when purchased.  I then loaded all Windows updates and upgraded to Windows 8.1.  Screen still flickered.  Actually flickering now as I am typing!!  Anyway, with original laptop I purchased a 3 year plan with inhome service so Lenovo sent repair guy out...twice.  They have replaced my screen twice and connectors from screen to base twice.  Repair found broken plastic screw holders that secures right and left screen hinges to base so bottom case under keyboard was replaced. Not sure how long this will last since this is a laptop and I open/close lid frequently.

 

Lately when I turn my computer on the flickering starts immediately.  I have turned off wifi with no programs open (Microsoft Office closed, Internet Explorer closed....nothing open) and flickering still happens.

 

In several posts for other models I am reading this flickering is a persistant issue.  Video card and connectors have not been replaced and am going to call support again and have guy come out.  When I first reported this problem (after doing a lot of internet seaching and found a lot of communication on this) I asked Support if they were familiar with this issue.  He said No.  I am VERY surprised that Lenovo has not found solution and have not advised their Support team since I believe this is a defect in their product.

 

I wll problably wait out my warranty and get support when needed.  But do not think I will be purchasing another Lenovo.

Have you reinstalled your video driver? Because that has to be the problem, not hardware.
