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

I have a vertical green line across the screen

Check the cables.

It might be overly simplistic, but if your monitor is connected via a serial cable, one of the pins might be bent or missing.

This can cause slight display problems, including a vertical line.

If you are using a USB, try another cable and see if the problem persists.

Update your video card driver.

Some discrete cards have an update feature in the properties window for the device.

Right-click on your video card in the programs list, and select "Properties."

The update will be a button under the "Drivers" tab if your device is so equipped.

If not, visit the manufacturer's website and search for the most current driver for your model number. Updated video drivers could solve the problem.

Place a box fan directly behind your computers intake vent for extra cooling.

Sometimes if there are system problems, your components can run too hot.

If cooling the computer takes away the line, you know have you an overheating problem, not a monitor problem.

You might try cleaning the internals with canned air.

Remove the housing, and thoroughly blow any dust, hair or carpet fiber away from the fan and off the mother board.

While you're there, you can check to see if there are any obvious loose connections.

Connect the monitor to another computer if you have one available.

This is probably the most definitive test of your monitor's health.

If you have a line when the monitor is connected to a different machine, it's likely time for a new monitor.

As frustrating as it sounds, taking apart one of today's monitors in an attempt to repair it is more expensive than buying a replacement.

If you don't have another computer available, try shutting down the computer but leave the power on to the monitor.

Using the buttons on the monitor bezel (if you have them), call up the settings.

If the line appears in the menu just as it did in the video from your computer, then you definitely have a monitor problem.

Replacement is probably in order

Hope this helps.

Computer will not boot to normal and verticle lines on monitor, dell XPS410, windows vista 32 bit

Unplug the monitor video cable from the computer. Power on the monitor and see if you get the same results. If so then your monitor is defective.

Suddenly a very thin vertical yellow/white line appearing on my HP desktop monitor? pls help

Does it appear THE MOMENT you turn the unit on?

If it does, then you will have to run the monitor's self-test function by turning it on with the data cable (the one that does NOT connect to the power outlet) DISCONNECTED from the computer.

If the line still appears, then the monitor is faulty & cannot be "repaired". Usually, the entire LCD module is replaced.

If the line does not appear in the self-test mode, then check if it's connected to an ON-BOARD display adapter (typically found in the back of the machine, towards the middle area, towards where the ethernet cable and USB devices plug in) or a EXPANSION CARD (normally located towards the BOTTOM part in the back of the machine).


If it plugs in to the on-board slot, then the motherboard may be faulty. If it plugs in to an expansion card, then it's the card that may need to be replaced.

Of course, these are merely possibilities, but the most likely failing component here is the monitor itself. Busted display adapters very rarely, if at all, manifest these horizontal or vertical lines and STILL boot up. Regardless if it's on-board or expansion card, a failing display adapter would normally have either no display at all, or it would just simply stop booting up (screen remains dark: no lines).

When I turn on computer, the monitor say going to dpm mode. any help?

DPMS (Display Power Management Signaling) is a standard developed to save energy and maximize the useful life of computer displays. By switching the horizontal and vertical sync lines on or off, a DPMS compliant video card provides the capability to place the monitor into one of four modes (Normal, Standby, Suspend, Off).
Each mode puts the display into a different powered state from fully powered up, to the Off mode. In the Off mode, only a small auxilliary circuit is running which monitors the horizontal and vertical signals to wake up the monitor.

A memory chip on the video card has just died and it's causing data corruption. There is nothing you can do, the card is dead and will have to be replaced ASAP.

Getting vertical line in acer monitor

Apparently it is a display hardware problem. Try another monitor with the same cable and video card. Then you should try another cable. Then another video card. If vertical line doesn't show in either case, then you should replace the appropriate device\cable. If it shows anyway, then bring your monitor to service center for diagnosis.

Try another monitor, then change the graphics settings to lowest possible, then reboot the PC, and see if your screen works again, if it does, check the documentation for your monitor and make sure you do NOT exceed the maximum color depth / resolution for your monitor, also, make sure not to exceed the refresh rate.

if this does not fix your monitor issue, check the cables for missing pins, freyed wireing / broken insulation.

Again, if this doesn't fix your problem, try the monitor on another PC, and if still a no-go, you may have a damaged inverter board in your monitor, or other componant / wire based issue.

If another monitor doesn't work on your computer, try swapping the graphics card out, it could very well be a dieing graphics card.

Computer only displays vertical lines and pink background.

Most likely an issue with the Video Card or Video driver.
* Boot to safe mode by tapping F8 while starting up the computer. Selected safe mode with the keyboard and hit enter. Login to your user account. You should see the words “Safe Mode” on all four corners,
* Open device manager – Right click “My Computer” – Select “Manage” – Selected device manager from the left. Under display driver, you should see your vide card listed. Right click on it and select “Disable”.
Now restart your computer and if this resolves the issue, then the vide card may be at fault. You could also try updating the video driver.
Do let me know if you get this far.
