FAILED BOOTING OR DARK SCREEN ON PC

It’s my pleasure to share this vital information with you detailed and without charges, what I will be talking about is “Failed booting on PC”, by now PC shouldn’t be a hard word but for the sake of beginners, it simply means “Personal Computer”.

Dark screen or failed booting as some might call it is common in older PC as well as new ones, not because the owner is careless but due to time per numbers of operation. I use that for logical reasons.

It is common the PCs that generate greater heat, though some will say AMD processor are always a victim, but I totally disagree, AMD is emphatically modeled and equipped with metallic materials that make transfer of heat easier and circulatory. Some will dispute that but I leave that debate for another day.

When using your PC, the processor generate heat due to current intake and task at hand, over time the heat is greater and your heat sink has to be perfectly structured and always ready to absorb heat in such an out flow direction. The position of your processor determines the location and direction of your heat sink flow of heat. For laptops, its always by the left hand side of your system while facing you and for Desktops, Its mostly in the middle of the motherboard on top of the processor with the heat sink thereby blowing the heated air to its environment and the chassis fan transfer it out of the system casing, regardless of where it is or how it’s been structured, the primary objectives is to absorb it, transfer it from the processor to it tail end where cooler fan and probably chassis fan can blow the hot air out of the system for continuous cooling system, just like a car cooling system.

Why all the above explanations?

Well, it’s good to know the source of one’s problem, don’t you agree? That explains one to the causes of failed booting or dark screen in PCs

How does that affect booting?

Good, since heat is generated from such a consistent source of operation the term linear expansion applies. The heat sink is not only design to carry heat mainly from the processor but as well from the display chips and other chips that generate heat. When one of these (Cooling fan, Heat sink or cooling paste) is malfunctioning, then your chips and processor start to overheat and since there are not heat guage in most PCs, your systems begins to shut down unprecedentedly, thereby warring  down the longevity of your PCs operation period in some cases it burns the processor, display chip or make the soldered lead melt and makes no contact with the pins or circuit board thereby making operation difficult and impossible but mostly  burn out the RAM or Blow electro-hazardous dirt to the base of the RAM and infecting it metallic legs or pins thereby detaching from the RAM bus. Hmmm, RAM?

Yes RAM (Random Access Memory), from this point of view I will not go into details how it works or where it’s located but for now, it’s in a slate form, its embedded and in most cases detachable and replaceable if its not an onboard ones. The RAM get heated as well but this time, gets overheated because it’s the second inline to be called into action immediately you power up your system. Pressing your power button, it send digital signal and current to the processor (I know some have a diverse idea but let’s leave it that way), display chips and waiting for the internal memory to tell it what next to do which could be to boot, or entering BIOS or postpone booting for reasons best known to the User. Though some will argue that the firmware is to perform this task but I say, Firmware translates the default settings, factory installed components and identifies the hardware install while the RAM compliment. For the sake of this post, take it that way and let’s leave the debate for future.

Still don’t get it.

It’s simply means one way or the other, the RAM gets faulty and hinder the boot process either pre-boot or post boot. The aforementioned causes are the sources of failed booting or dark screen expect for a damages screen which I think is easily detected by pressing Caps lock, Numbers Lock and checking the leds if responding, then your problem is with the screen itself otherwise solution to one or these causes above should resolve the issue.

Solutions:

Some will jump into conclusion by saying, replacing it. But I say, check out the problem, correct the defect before replacing any parts because if you replace without correcting that, you might damage the new parts as well expose your PCs to greater damage and finally destroy the Motherboard.

Also, while replacing, replace with component of same ratings and configurations.

Note:

In technology, there’s nothing you need to force in replacing or disassembling nor assembling. What doesn’t fit doesn’t fit period. Check the directions, lift the clips, don’t tamper with the jumpers unless you understand it settings and before replacing, disconnect completely from mains and battery including CMOS battery.

To before warn is to before harm. A word is enough for a wise.

Thanks for being there, thanks for reading and finally, thanks for making me a poster.
