Hello, I hope I can explain the problem well. My monitor is a CRT. The ghastly black lines/stripes emerged just today, gradually by a few secs. When it happened, the quality of the picture lessens a bit and stayed on like that.

Its something like this,
Not an accurate representation though. The faint stripes appears and becomes more apparent if there is a line on the monitor, be it text or pictures. The whole screen is like a barcode.

Is there a way to cure it?

You may want to ensure that it's the monitor and not something else. If you can, try your monitor on another machine and try another monitor on the affected machine. This will tell you if the problem is the monitor or the machine.

Sometimes strange things can happen if there are badly behaving electrical devices on the same circuit. Turn everything on the circuit off (printer, fax machine, overhead lights, everything) and see if that clears the image at all. You might also want to try relocating the machine in a different part of the house and see if that makes a difference. This may sound silly, but I remember a person who had a problem with their monitor after they installed a new flourescent light that was introducing interference.

If you try other monitors on the system, and they show the same lines, you most likely have a graphics card issue.

If you try the monitor on other systems and try the monitor in different locations and the lines still show, your monitor most likely has a power supply issue. I believe that this is repairable but, unless your monitor is very expensive, is really not worth the costs of repair.

If you run any of the tests that I describe, please update your post with your findings.

Heya, I've did your tests and I suppose it is the graphics card that is the problem. Thank you for helping me deduce the results. Appreciate your detailed informative post. :) Now where can I get the money to buy a new card..... Lmao.

Where does one get a new graphics card and how do you install it?

A graphics card can always be purchase at any computer repair shop or computer score. If you are inexperience with installing it, i suggest you ask an expert to help you. Maybe the person who sell you the graphic card will be kind enought to do that.
