My computer is running but I am facing a problem that is my screen appears broken down when I want to convert anything  or viewing image in my computer. Why and how can I solve this problem from my computer forever?
From your description, I assume that the issue is that the computer hangs whenever you try to view some media or any task which consumes memory.

I think your problem here doesn’t concern your monitor. If the image on your screen sometimes suddenly freezes, especially when you are viewing graphics or maybe a picture, try uninstalling your video card’s driver from the Device Manager.
After that, check your computer for any possible errors. Use a disk utility application to check the system. For a much thorough diagnostics on the system, use a disk utility application like Norton Utilities, PC Tools Performance Toolkit, or Norton SystemWorks. After the disk check, install the video card’s driver again.
This will fix any corrupted files in the installation and will restore the settings back to default.
If this doesn’t help and your screen still appears like that, try updating your video card’s driver. Using your web browser, visit your video card’s website then download the latest version that supports your operating system.
