I'm crossing my fingers:

i) sometimes the cable that connects to your Hard Disk(i.e., both data cable and power cable) may i would suggest you to open the computer tower and reseat data cable, power cable present on Mother Board and Hard Disk ......

ii) u can alo try reaseating(removing and replacing it again) RAM (imp: place it properly....)

from my personal experience sometimes due to improper placing of RAM may lead to such vertical lines  or may be due loosen contact of data cable or power cable.....

Thanking you

Display vertical line

Turn off the monitor and disconnect it from the back of the pc. This way you will isolate the monitor from the PC. Now turn on the monitor, if you still see the vertical line then that means the screen is bad and you would need a new monitor.

If the monitor doesn't have the vertical line then that means your video card is the issue or if you have an integrated vga port on the back of the computer then the motherboard is bad and would need to be replaced.

When I turn on the computer it displays continuous vertical line patterns on the monitor

If monitor is fine, and cables too, then is a problem with VGA. If the VGA you're using is build in MB, then it might be that. Try to use a VGA card or another VGA card.

On our office, we have 5 Acer X163WL monitors, 2 of this monitors have Multiple vertical lines on the left side of the screen. The computers don't have video card, so i think its not computer that have...

Computers might not have separate video cards but in that case the video cards will be integrated into the computer motherboards - on board graphics!

Monitors might be affected by electrical interference. Best plan is to swap the monitors around and see if the vertical lines persist on the two potentially faulty monitors and if that is the case the monitors can be declared faulty.

Half side has vertical lines

Turn the computer OFF and just turn the monitor ON if the vertical lines are still present then the issue is your monitor, but if there are no lines on the monitor alone turn the computer ON then go into the BIOS either keep on tapping del key once you turn the computer ON or keep on tapping f1 to get into thew BIOS screen.
If the vertical lines are present in the BIOS the issue is the Monitor but if not and the lines are present in windows the issue is your video card.
Replace the video card, if you don't have a video card and you use the built in video card on the system then the motherboard needs to be replaced.

Vertical lines on inspiron 9300 laptop lcd

The possible reasons for this could be;

1.)A loose connection between either the graphics card and the computer mainboard or between the Graphics Card and the Computer Monitor.
2.)Your LCD monitor has become faulty and either needs to be repaired by a technician or replaced.
3.)Your graphics card need to be cleaned, clean the gold finger contact on the card.

However in my experience I would say that the monitor has become faulty, try this monitor on another computer and if it still displays vertical lines then you know that this is the case.

If your monitor works on another computer then I would say that your computer or Graphics card is having some troubles.
Overheating plays an important role here.

Kind Regards

Turned on and just get vertical lines

if you have tried an external monitor to the laptop and it is still giving the same display then I think that there is something faulty with your vga or display card..Check the manufacturers website and it could be a driver issue but if not then it's time to get a new pc..unless you have the knowledge of going further..Please leave a voting for my help.Many thanks...

LCD 19" Samsung - one half od display has yellow vertical lines

This is surelly a internal failure in the LCD monitor. one of these 2 problems occured. Both of them will however require some profesional service repairs (if they even are possible) 1. You may have a faulty connection between the main board of the display and the LCD pannel. Even if only one wire or one singe pin isn't connected properly the results are pretty spectacular (weird lines on the display, lack of image or weird patterns appearing and so on) 2. The video controller chipset on the mainboard (inside the monitor) is broken and needs to be replaced (however it is a small chance you will find a replacement). I'm sorry if this isn't helpfull but the nature of the problem makes the diagnostic easy but the solving of this problem pretty hard. Good luck.
