Computer beeps give a message to you

Read More About Computers

One beep from your computer at startup can style your intact day. Just ask anyone that has turned on the PC and suffered the agony of some beeps and therefore nothing. When you obtain a computer, it will make your mark in the company of the BIOS (Basic Input/Output System), pre-installed on an EPROM (Erasable Programmable read Only Memory), chip on the main/motherboard. When you initiate your computer the CPU (Central Processing Unit), sends inspection of the PC to the EPROM BIOS. The BIOS is section of the POST (Power-On Self Test) of the computer. Once the BIOS receive the go ahead since the processor it starts its magical journey over all the components and peripheral procedure attached to the computer.

To a large extent like the human mind, once we wake up in the morning our brain remembers that we have eyes, ears, a nose and so on. We identify the town we live in. You be capable of go to job, stop by the post office, the grocery store and back home lacking having to spend time perusing a map for directions to each one. Your computer works greatly the same way. Not including a memory device to instruct the computer on what is where, the operating system and other software would factually have to take the time to locate each part of the PC and its components every time they are loaded. Opportunely, the BIOS take care of that for the processor, operating system and components.

How the BIOS work?

All computers come pre-loaded with the BIOS on the motherboard. Motherboard manufacturers work long hours with BIOS manufacturers to make sure the information in the BIOS is certain to the requirements and components of the motherboard. Although there are a number of BIOS manufacturers, the two most popular are AMI (American Megatrends Incorp.) and VIA. BIOS simply put, is a program and not a definite device. The BIOS also lets you appreciate when there is a riddle. It accomplishes this by checking for known devices and makes sure they are still attached. When the BIOS uncover a problem it sends a series of beeps to the motherboard speaker. This series informs the user of what the problem is, at least as well as the BIOS can uncover. Let's say your video card has gone the way of the XT model computer, the BIOS senses that it has died or is not installed. The BIOS sends a series of beeps to the onboard PC speaker to notify you of the problem. Pretty trouble-free. The problem is that no manufacturer of BIOS uses the unchanged beep series. This is why it is important for you to live through the BIOS software manufacturer for your certain PC. We will vindicate how to find this out later.

How do I be familiar with if the BIOS are working?

That is simple, if your computer starts and you get a single short beep, the BIOS is working and has found and relayed the information vis-а-vis the input/output devices to the CPU. If you turn on your computer and nothing happens at all, the riddle is probably in your power supply (this assumes that you have it plugged in properly). The BIOS is probably still working but the computer can't start because of a power problem. If all is well, the BIOS will find all the attached input/output devices, fire a single short beep to the interior speaker and the computer will set up the boot method.

Let's say you added an external modem to your PC on Communication serial port number 1(Comm1), and no matter how many times you install the drivers, you cannot get the PC or Windows to appreciate it. Chances are that the BIOS do not know that the modem exists. Entering the BIOS setup and changing it to let the use of Comm1 will stick the problem and permit the PC know that a device exists on that port. This is the most customary use of the BIOS setup and also the easiest to puzzle out. WARNING: it is just as trouble-free to totally screw up your system by making changes in the BIOS setup. So be careful and make sure you be aware of how and what to change.

Changing the wrong settings can render your computer useless. There, we warned you twice, that is because we want you to judge twice before you change the BIOS. Second is the Flash BIOS update from the manufacturer of the BIOS. This is a software program that the manufacturer of the BIOS sends out periodically to assure the BIOS conform to new tools and standards. You can normally obtain this software upgrade from the manufacturer and sometimes from the motherboard manufacturer. Be careful, be very careful installing the software and be confident that it is for your exclusive BIOS. Always see the manufacturer's advice exactly. The third way is replacing the BIOS chip. Replacing the chip possibly will be your only recourse and should be left to pro computer repairmen.

How do I see which BIOS I have?

That also easy, the computer will truly tell you. If you are fast enough, you will consider it the BIOS name and version on the screen the instant you turn it on. If you are not a speed-reader you can edit the BIOS setup and retrieve the information from the setup program. You may also e-mail the motherboard manufacturer and catch which BIOS was installed on that board.

As stated earlier, the beeps indicate something. They can present you information on problems that the BIOS encounter. Acquaintance your BIOS manufacturer to find out what every one beep series means. Armed with this information you may well be able to figure out why your PC has stopped working and avoid scratching your head and noticing this gigantic question mark floating over your PC.
