Unplug AC Charger. Kindly check the bottom part of the display if it still flickering while the ac adapter is unplugged. If system stops flickering issue was due to unstable charger, you may need to reseat the power cord or maybe replace the ac adapter itself.
On the other hand if display still flickers after you disconnect the charger kindly reinstall the display
driver. Since I don't have any idea what operating system youre using right now, I put all the link for all the available os for the graphic card driver.
For windows 7 (both 32 and 64 bit) Click
here
For Win vista os with Intel Graphic card Click
here.
For Win vista os with ATI Graphic card Click
here.
For Win XP os with Intel Graphic card Click
here.
Make sure to restart the computer after the installation. If same problem occured, please contact the computer manufacturer to have the video card replaced.
Should you have any other questions please leave a comment.
Cheers~
