What does DOA mean?
The first two, D and O, stand for Dead On Arrival. Dead means that the product is bad when it reaches your hands. “On” refers to the time you get it. If a person is dead on arrival at a hospital then he or she dies just after reaching the hospital. Similarly, if a computer arrives at your home with parts failing or something else wrong with its hardware or software right out of the box then you call it DOA.
Most motherboards that hit the retail shelves are dead-on-arrival (Doa). Doa boards, as they’re commonly called, fail to function properly when first turned on. Doa boards can be caused by either a faulty manufacturing process or the condition of the motherboard itself before it was packaged.
Doa Motherboard symptoms?
Doa motherboards are easily identified by the multiple blinking lights – on and/or off but not on – that light up when the computer is first turned on. One or more of these lights indicates that something is wrong with the motherboard.
Doa motherboards can be repaired if they’re structurally sound, but faulty manufacturing processes and shipping conditions often result in damaged surfaces, which are difficult to repair. Electronics technicians use a process called desoldering to remove the component from its position on the board. Desoldering requires special tools and knowledge of desoldering techniques; both are expensive investments for electronics stores and individuals trying to recoup some money from their Doa purchase.
Why does the DOA Motherboard occur?
DOA is commonly caused by inappropriate PCBA components, circuit design, or human factors during production or operation, such as insufficient testing before shipment due to space constraints in the workshop or cases in which poorly trained workers failed to follow the inspection procedure or use an improper testing method.
How often do motherboards need to be replaced?
DOA must be solved as soon as possible during production and operation in order to minimize the loss for each DOA case. The whole responsibility of dealing with DOA lies with system integrators and distributors, who shall work together with suppliers to improve their respective operating systems and quality control.
It is important to replace motherboards every 3-5 years so that they do not slow down the computer system. There are several reasons why this is necessary. Firstly, after several years of usage, a motherboard will become slower than it used to be because of dust and dirt accumulation.
As well as slowing down your computer system, these particles can also damage the contacts of components and cause them to overheat or short circuit. The chips on the motherboard contain microscopic circuitry which can wear out with time and use. This could result in errors being displayed on the screen and prevent you from using certain programs such as games or Microsoft word processors.
Failures of Motherboard is a Serious Issue:
Motherboard failures are a serious issue. If you ask anyone who has built their own rig, they will tell you that out of all the components, the motherboard is probably the most important. This is because it controls pretty much everything else and without it, you have nothing. This means that if your motherboard fails, you are looking at a very expensive repair job or an even worse scenario – having to build a new rig from the ground up again.
Every year motherboard manufacturers are given a certain percentage of failed motherboards based on the number they made that year. They then take these faulty boards, test them, fix them if necessary and put them back into production in case any other customers have issues with their units.
This process is done regularly every year so while some people assume it’s because of shoddy workmanship, late shipping, or even poor handling by the shipping company, etc., it could be due to something quite different – design flaws in the original product itself. In fact, many times what was thought to be poor quality control was actually an issue caused by a major problem with the design of the motherboard itself.
The Shocking Doa Failure Rate Of Motherboards!
Let’s start with a motherboard that not many people seem to know about – the Gigabyte H55M-UD2H. According to one retailer, this motherboard had a doa rate of 21%. Compare that to more popular motherboards like the MSI P67A-GD65 which only had a 4% doa rate and the Asus Maximus IV Extreme Z which had 2% for 2011/12 with an average overall of 1.4% for all models. This is from data collated by Newegg and Amazon respectively.
