How to change the train

The loop is a binding thread between the motherboard of the computer and the peripheral devices connected to it. Often, one of them either ceases to work adequately or does not work at all. It does not always indicate a breakdown of the device, perhaps the fact is that the loop caught. Here and change it to start.

Disconnect all the wires that go to the system unit by pre-extending the network wire from the network. Remove the bolts on the side lid and open it. Visually inspect the inner space and find the plumes. They can be two types - IDE or SATA. The first is old, it can be found more and less often, the second is new, both standards are now used.

Check the condition of the loop. If the old computer, then most likely you have an IDE loop is flat, wide, 40- or 80-core wire with three plugs. Usually two wide loops are used in the PC, one for DVD, the second for the hard disk. There are options for connecting a floppy drive, but it is outdated and now rare. There are hybrid options using both standards. When observing the enlightenment of the computer, correcting only a rough reboot, you need to change the loop from the hard disk, while reading from the DVD disk - then the plume from the DVD-ROM.

Gently disconnect the loop from the hard disk, there are cases when two devices are connected to one IDE. Then you need to remove the second. Holding the motherboard, not allowing the deflection, take out the plume from the connector.

Disconnecting the SATA loop. It is much smaller in widget than the IDE. Fastened easier. Such a loop is connected only one device. SATA sockets are always present on new motherboard models. Find the IDE hard drive is now a difficult task. New are not released, therefore most models in the used market.

Diagnostics. The diagnostic process is as follows:

Replace old loops on new, in the correctness of which you are exactly sure. In the reverse order, like when disconnected, first connect the loop to the motherboard to the corresponding connector. Then to the device.
Connect all previously disconnected wires to the system unit. Mouse, keyboard, monitor. If necessary, also an acoustic system.
Turn on the computer to the network and the power button on the front panel.
Wait for switching on and self-diagnosis, after which a single beep sounds. After loading the OS and the successful definition and operation of the problem node, collect a computer.
If the signal was not or the computer did not turn on, check the connection correctly. Alternately replace the loops before reaching the normal operation of the computer. When the stable operation of the system is achieved, once again turn off the system unit from the network and make an assembly in the reverse order. Check out no extra details or loops without taking into account replaced elements. Close the side cover, screw the bolts.

With the right execution of the proposed instructions, the loop replacement will take you little time. If nothing happens, read again from the very beginning and try again. Often replacing the loop solves the problem. Perform all actions with caution! Computer equipment is a high-precision product and requires a careful relationship. Good luck in work!
