what is a motherboard
motherboard like when she tells that story that I've heard like a hundred
times about when I was young and crayon up the nose and man I just wish she'd
stop telling that story that's a joke no where the CPU or
the central processing unit is colloquially referred to as the brain of
a PC the motherboard or the main board is often described as the backbone it's
the component in a PC and for that matter pretty much any other electronic
device whether it's a game console C device a piece of industrial equipment
or a cell phone that contains all the slots that everything else goes into all
right so how do I find it Well that's usually pretty easy because it's the
largest PCB or printed circuit board inside the device and it's covered in
slots connectors chips and other electronic dude ads at its very core a
motherboard is just a bare PCB and contains no actual processing power it
relies on other processors like the CPU and GPU which are sometimes socketed in
and at other times soldered on directly to perform all of the actual work and
give life to your device but that doesn't make it simple motherboard
designers are tasked not with creating a simple platform onto which everything
else will be stuck like Lego but rather with crafting an infrastructure for some
of the fastest and most delicate Electronics imaginable even though the
majority of the other components used in the system aren't manufactured by the
motherboard maker they are responsible often for choosing these components for
their placement and configuration and making sure that every signal will be
sent where it's needed interpreted correctly then passed to where it needs
to go and all of this without excess interference even something as seemingly
trivial as a single trace that's a little bit too long can cause one
electrical signal to be a little bit late and another a little bit early and
cause instability that's why you'll sometimes see little zigzag patterns in
the traces on a PCB those aren't for beauty they're not for looks everything
about a motherboard is highly functional
a motherboard also isn't purely Hardware either there's a software or firmware
component on a PC this is referred to as a BIOS or UEFI and is often the
difference between a good motherboard and a great motherboard this software
acts as a way for the manufacturer to correct small bugs that are inevitable
with something so complex and to add functionality in the future it also
serves as a way for the user to alter settings or tweak them for optimal
functionality on consumer electronics this software component also exists but
it's normally not user accessible all right so what if my motherboard dies
which might even be while you're sitting here watching this video well for consumer electronics and phones and
whatnot you're often hooped if you can find a new one there are often extremely
fragile cables and connectors attached to them and if you can't find a detailed
guide on a site like I fix it for example I would recommend leaving it to
the pros for a PC life is a bit simpler many PCS use industry standard
components including the motherboard but many others use proprietary and
expensive Alternatives so the only way to find out for sure is to contact your
manufacturer directly but there's a good chance that you'll be able to get your
hands on something once you've got a new one replacing a PC motherboard is in
many cases not difficult but it can be
timec consuming and tedious and will usually involve removing pretty much
every other component in the system in order to extract it and replace it the
good news is you can check out one of the excellent PC build guides on my
other channel and that'll tell you pretty much everything you need to know about installing a motherboard any other
questions you might have can likely be answered on the lineus tech tips.com
