White Screen/ thin blue vertical lines

Check the cables, try a different monitor, try this monitor on another computer. This will isolate the problem. If it is the monitor, it is not worth fixing, usually. It is far cheaper to make things than to fix them. If it is the computer, a new video card can be installed.

Will my Envision 19" monitor,

You will need to set the display resolution and vertical sweep rate on the computer to something the monitor can handle. The monitor works best at 1440 x 900 at 59.8 Hz vertical rate. If your laptop's graphics chip doesn't have this setting (available settings are listed in the Display control panel), then look on page 19 of the monitor's owner's manual to find something that matches a resolution listed in the control panel.

The screen when powered ON shows vertical colored lines from top to bottom. what can i do to resolve this?

Problem 1-cause from monitor or graphic card
Either the monitor is going bad or the video card is going bad. If you can get your hands on a spare monitor, try swapping it out and see if the lines are still there. If they are, then the problem is with the video card. You'll want to replace the video card if that is the case.

Try restart your pc in safe mode. It will disable vga mode. If you are using pci-e card(external graphic card), try to change using internal graphic card to check wether that problem is cause from graphic memory problem.If your motherboard have internal memory, then you can change using internal memory. If your motherboard dont have it, that you need to buy new external memory.Before that, you can try clean and clear using eraser, to clean dirty at gold contact .
example link to follow.

Problem 2-cause from ram module
Ram modules can also cause vertical lines on a monitor.It's hard to believe but i have experienced it multiple times.The ram is detected by the system,yet the display is corrupt.If you open up the pc and touch the ram modules the lines go away.This is very rare yet a possible cause and easily overlooked.

Same like memory graphic. Link
Try clean the dirty. Or if it cause from overheating, try using fan for ram.

Problem 3-overheating in graphic card

The video card could be over heating which causes what you are seeing, lines can also be called "Artifacts". Try opening the side of your case and see if you see these lines. Also, it could be a driver issue, try cleaning out your drivers using Driver Cleaner, and reinstalling the appropriate drivers.
If you have another computer, if the video card is a expansion video card (Meaning you have it in a PCI/AGP/PCI-E slot) try it in another computer to see if the problem persists, if so your card is probably bad and needs to be replaced.


For this problem, actually, i try using fan.

 Absolutely is solve the problem. i'm added internal fan, modified it for to cool graphic (PCI-E). fOR THIS CASE, mostly the problem you face is your pc will restart, or suddenly your screen became white. However, you can try.

Problem 4-magnet radiation

Also check to see if there are any magnets near the screen or hard drive.

For this, make your screen like rainbow. and sometimes, it make your screen, showing the line and it also will cause problem with your pixel in screen/ monitor
