The motherboard is, perhaps, the most important device in the computer. All important components of system, such as the hard disk, random access memory, external cards, the processor and the videocard is connected to the computer motherboard. It also is defining in a choice of the processor and in what cards and in what quantity you can use, what peripherals can be connected. Therefore it is obvious that any problem in the motherboard will result in not operability of the computer. Let's consider as it is possible to define malfunction of the motherboard.
Testing and search of malfunctions.
Each concrete brand of a payment, usually has the set of the software intended for testing and diagnostics, it can be downloaded from a site of the manufacturer of the motherboard. Having loaded and having established the software, further follow instructions of the manufacturer.
Reboot and enter the configuration BIOS settings. Write down the current settings and dump the BIOS settings (option "by default"). Here you can read article how to make dumping Bios.If to the system unit, any peripherals are connected, for example, the printer or USB disks, disconnect and disconnect them. Disconnect a hard disk, memory and the processor, take out them from the corresponding slots and wipe sockets dry fabric, further accurately insert back into the slots and sockets. Pay attention that all devices and wires were connected correctly. It becomes to exclude breakage of these sockets proceeding because of oxidations. Having collected system, connect the computer to power supply and start the computer. If the computer wasn't started in a regular mode, means it isn't oxidation of sockets of our connected devices.
Finally to find a cause of defect, it is possible to arrive as follows, switch-off the computer and take out from slots all devices what only probably, except the processor and the videocard. For the test of the motherboard, it is desirable to connect the serviceable videocard. It is possible to borrow at any companion, the main thing that the videocard had identical sockets. Turn on the computer and try to load bios if BIOS is loaded, and the computer normally will work, so it isn't the motherboard. Connect devices to system serially and check system work, yet don't define a "problem" component, it is desirable to begin with levels of random access memory. Usually if the knot isn't serviceable, the speaker publishes lingering peep. Replace it, reboot and adjust BIOS as it was adjusted until as you dumped settings in a state "by default".
Yes, still it would be desirable to add that before carrying out everything the described actions are higher, it is desirable to connect obviously serviceable power unit. In most cases the problem of loading of system consists in the weak or defective power unit. Often as the problem knot can be determined by signals of the speaker, it is possible to find tables in the Internet with interpretations of codes by determination of problem knots of the computer.
If you really found out that the motherboard failed, surely you have to know a little information how to learn model of the motherboard and to know about compatibility of motherboards.How to learn motherboard model.
The best way to check model, it to look at model number, having opened the system unit. You will see various slots and sockets of various flowers and forms. If the slot intended for connection of the videocard of average length, it, most likely, AGP, PCI-E slot longer. In any place of the motherboard will be or it is written on the payment, or the sticker with the model name is pasted.
One more way to define number of model of your motherboard is loading and start of some appendices which have been specially intended for this purpose which can be found in the Internet easily. If your firm computer also was assembled by the known producer, you also can check the payment name on a site of the producer if you, of course, know number of model of the computer.
Check of compatibility of motherboards.
There are two main companies by which producers of payments are guided, it is Intel and AMD. If you know model number, you can easily find the website of the manufacturer to receive all details concerning compatibility.
In case you use the motherboard under Intel processors, it has to have Socket 775, 1155, or 1156, these are the main nests, now in use for Intel processors. The nests intended under AMD processors, have a much bigger variety (AM3, AM3+,FM1,FX and so forth). Anyway, pay the attention, what number is specified on a nest, and then check the specification of this nest on the Internet.
