Video problems are the most devastating of the troubles your computer may have. It shown a dead blank display and leaves you clueless of what is happening inside of it. Don't get too anxious about it - we will solve your computer's video problem.
Having problematic video display may just be caused by a minor problem like loose cable connection to a more concerning defective video card or the display monitor itself. To be able to spot the real problem, it does not necessarily require you to become a computer technician. All you need is this short tutorial and some common sense at your disposal.
First, we need to find the root cause of the problem using a troubleshooting technique called "Zeroing of a Problem". The question is how do you spot the problem? Here are some questions that you should ask yourself while solving video problems.
Ask Yourself About:
- Does my LCD or LED display monitor have the right cable configuration or connection?
- Is it receiving power from the AVR?
- Are all the cables leading to LCD or LED display in good condition?
- Does the fan of the Power Supply Unit of the system unit spinning?
- Is there any whizzing or any other abnormal sound inside the system unit?
- Have you installed a new hardware or program earlier?
- Has the computer been moved to another location lately?
Now after trying to trace the last things done or the recent condition of the computer before it had any video problem gives you some sensible clues to where we should begin to locate its cause. Let us take the last question "Has the computer been moved to another location lately?", if you are to analyze the display problem may have been caused by the action. So what might have caused the display monitor to fail? Probably it would be from a power source, or loose cabling, or damaged monitors due to mishandling and other probability. You can then start checking for the suspected cause of the video problem one after the other. Do not check all problems at once - your check may not be thorough.
Loose cabling can easily be solved by reinserting it or as a temporary solution wrap the exterior of the plug with paper adhesive tape to snugly fit it in its socket. If however you have checked the cabling and power source and finds no fault or cause of the display problem, then it is worth to consider that the video failure might be attributed by the components inside of your computer.
To check the inside components of your computers, you must adhere to practice computer servicing safety measures and able to have some background in disassembly and assembly of a computer. So what particular peripherals or parts inside your computers that if it fails, it leaves you some disgusting display problems? Here is a short list of the possible defective peripherals that may contribute to the video trouble.
Defective Peripherals That May Cause Video Problems
- Video Card
- Power Supply Unit
- Hard disk
These are the most common peripherals that if they may fail, are usually the primary things that lead to video or display problems. Use trial and error technique by swapping each individual peripheral with a known good functioning one. In doing so, you will be able to "screen-out" other possible cause of the problem. But sometimes, cleaning the connector edge (the shiny gold colored plates) of the RAM and Video Card usually solves the problem. You can easily clean the connector edge using the commercial electronics detergent spray or a simple rubber eraser.
