So here is my problem, I have a Dell laptop that is about 3 and a half years old. it seems to have developed a sort of flickering distortion. At first I was thinking that it might have something to do with the connection between the the computer and the visual display, but it seems to do it consistently every 4 seconds or so, thus I am thinking it might be some sort of problem with the operating system. Is it possible that it is a virus of some sort, I know that I must have some sort of redirecting bug in my comp right now which I have still been unable to find and delete these past few days. Though I don't think this is the issue because I have been having this problem for quite some time. When the problem first started about 3 and a half months ago, it would stop happening after a while of being on, or I would just restart my computer and the problem would cease. The screen seems to have some coloring distortion, but it also seems to be a very jumbled version of what is already on the screen and seems to be separated into horizontal lines, when it is not flickering, the screen is completely fine, and has no evidence of anything being wrong with it. I did drop my computer on accident about 6 months ago, and my HD crashed, so I am working with a decently new hard drive, is it possible that somehow the dropping of the computer caused some damage in another part of the computer that didn't start manifesting until a few months later?
I would normally just take it to my computer services at college, but I am home for the summer, and they can't really help me. I would greatly appreciate a response from someone...Thank you.

Very possible. Connections could have weakened during the fall and continued use (heating/cooling) may have taken a while to get to the point you're at now. It's unlikely a software issue (but you do need to get the suspected virus/malware removed). If you're not comfortable working on the inside the machine (or taking it apart), take it to a technician who is experienced in such...

Why would the disruption in the display be like clockwork then?

What TRA said is true.


You could also try plugging the laptop into an external monitor just to find out whether it could actually be the laptop monitor or the graphics card is damaged.

I would probably check your temperatures as well for your graphics card, cause it could be possibly overheating.


Hope this helps.

Hi DaviW

My name is Vikram and I work for the Social Media and Community Team at Dell. I regret to hear that your system's display is flickering. This is very much possible that the issue started as the system got dropped. However, you can try connecting an external monitor to see if the system works fine with it. Alternatively, I will suggest you to re install the video drivers on your system. Please refer to the following link:-

Please select your system model and operating system. Please click the video driver from "Video" category and save it on your desktop. Once done, click on "Start" from your dekstop and type in the search box "Device manager" and press enter. Right click on the video driver from "Display adapter" and also check the box to delete the supporting software when prompted. Once the video driver is uninstalled, restart your system and re install the video driver that you saved on your desktop.

You may also check your system in "Safe Mode with Networking" to see if video flickers there or not. Please find below mentioned steps to go to "Safe Mode with networking".

Please restart your system and keep tapping "F8" as soon as the Dell logo appears. Select "Safe mode with networking" and press enter.

If this reply was helpful or if you need further assistance,kindly respond here. I will be glad to assist you to the best of my knowledge and ability.

Thanks and regards
