alright guys, if your looking for someone who knows about this Vertical Lines on laptop screens-- well, its a good thing i spotted this forum-- I'm the guy you need.
Normally Laptops screen are very fragile, and they break easy when pressure is exerted on to them. Just a simple flip of the laptop screen in a fast aggressive motion could damage the screen gradually (which i seen kids do all the time).
If you have done this over the years, a yellow or a "colored" line appears, that means you have damaged your laptop monitor.
The only way to fix it, in this case, is to get a new monitor because its permanently damaged.
Lets say you are gentle with your laptop and never caused any harm to it. However, one of those lines vertical lines appeared up on the screen just after you initiated a "memory hungry" program such as Video games.
The vertical line is due to an exhaustion of the graphic card at one Instant of Time, this stress related issue is then cached on to the systems memory, meaning it saves the Stress on to the memory and it will never be forgotten. Resulting into having that frustrating vertical line on the computer.
Simply rebooting the laptop will not resolve the issue because it is stored in in the System Memory. There are two ways you can resolve this issue.
1. To remove your systems memory chips when the computer is off. Then turn on the computer. When the computer is finished, you will notice that the computer does not boot into windows etc. Press the power button to "cold boot" the system. Now that the system is off, install back in the memory in to the appropriate slots. Turn on the computer and the problem should be resolved. This procedure is to have your whole computer refresh itself into thinking it has received newly bought Memory also meaning untouched\unused. This method also clears the memory and you are good to go.
If you dont want to take apart your laptop because of reasons of damaging the keyboard or the touch pad connections, then follow these steps into tricking your computer.
++remember how i said graphic card stress? Well, disable the graphic card from your control panel. (if you dont know how to get there its simple. Double click on my computer, find control panel)
Now in control panel, open up 'system'. Here you will see tabs at the top of the window. Click on Hardware, now click on [device manager.
Here another window pops up and it displays everything in your computer! Here click on 'display adapters'. A list drops down revealing all the parts responsible for your computers Visual aka graphics. Right click on the graphic card and disable it. Once disable the computer will ask to reboot.
When the computer is restarted, the vertical lines remain as if you didn't do a thing. This is because the vertical lines are still stored in your system memory.
Now that you disabled your graphic card, you have quarantined the problem from getting worse. From here we know the graphic card "[bleep]ed up" and we stopped it.
To deal with the system memory, we need to trick it.
Try running some simple programs like Internet Explorer or Firefox, something that requires the use of Memory. When the window is open try shrinking it to a good size box, the reason is because we are going to move this window around a bit to get your system memory kick in to gear. Now that you have a good sized box, click and drag that window slowly to different places on the desktop. You will notice that your computer LAGS a lot, due to a non-functioning graphic card. The computer is now depending on the systems memory to generate the correct image rather than using its graphic memory stored in the graphic card.
Now go back to your Device Manager, and Enable your graphic card. Once its enabled do not restart the computer. Close the Internet Explorer or firefox. Re-open the program again and you will notice the vertical lines flicker on and off. As soon as you see a good time interval of when the vertical lines are gone, quickly hold down the Power button of your Computer untill it shuts off--this will cause the computer to SHUT OFF IMMEDIATELY by power loss. Anything saved will remain in perfect condition, anything not saved will disappear. What we just did was freeze the system memory into a point of time when the graphic card was running "A -okay" allowing to override the system memory with a better image. While it was overriding we stopped the computer, so it will remain in that condition forever, and it will not go back to the Horrible vertical lines saved on the system memory.
Now turn on your computer and it should be in good shape. Sometimes you will see the vertical lines appear here and there, don't be alarmed, just ignore them and open a simple program once or twice. You will notice the Lines flicker when a program is just being opened. Restart your computer once more, or two and you should be completely free from vertical lines.
*******If this procedure does not work for you, it can be due to several reasons****
1. Permanent Monitor Damage
2. Permanent Graphic card damage from Heat
3. Graphic card driver conflicts
4. Too much dust inside of the computer capturing a lot of heat (you will be amazed how dusty laptops can get in the inside)
Changing of the hard drive will not do anything, do not waste your money in this way. This is how manufactures want you to think.
If you trying desperately to get rid of this problem without buying a New computer\ laptop, you need to think, "what are the devices\hard wares responsible for visual and graphics?" "What would cause a faulty image when the graphic card is in good condtion?"
If any of these conditions do not apply to you then there is not much to say other than the Motherboard is damaged, giving funny errors and the blue screen of death.
If this was not useful, i'm sorry. Your computer could be damage beyond the issue we are trying to fix ( Vertical Lines on the desktop).
If i did not explain my procedures clearly please say so.
