Repair and maintenance of computer hardware services

What is the hardware? Hardware components such as the monitor, keyboard, Central Unit (CPU), mice and other input/output devices (input-output) is a computer. The monitor, keyboard, mouse devices and i/o operation is heavily dependent on the CPU. Some less important causes such as loose connections or saturation, can be one of them may stop responding (hang). A few troubleshooting tips can be followed to correct these minor errors.



Disturbances in the processor are more dangerous, because it is a very complex structure. CPU is a meeting of the motherboard, hard disk drive (HDD), memory (RAM), disk compact-read only in car memory (CD-ROM) and the floppy disk drive. Less you are familiar with the hardware of the CPU, it is extremely difficult to determine exactly the where the error occurred. If any of these components will be not able to run, there are some repair tips that can be followed. To view the circuits in the processor, the housing should be deleted.



Motherboard

The full operation of the computer depends on this component. Processor-game chips, with which all the logical operations of the PC, is integrated into the motherboard. Ribbon cables, power supply, CPU and RAM are the first things to check on the motherboard. Verify that the Ribbon cables or the power cable is loose. Check if the memory chip RAM know more about the slot. The CPU (chip embedded in the Board of Directors set) is all marks outside does not appear if it is blown. The only way to check the CPU or not working, is piloted by mounting it on the motherboard to another PC. The motherboard is a clock in real time, ROM BIOS, CMOS RAM, RAM sockets, sockets or slots, slots of CPU cache RAM, keyboard controller, interrupts, internal and external connectors mounted on it. Don't mess with these elements, except if you everyone knows well. Do not touch the motherboard without the power to disable.



Hard disk drive (HDD)

Also known as a hard disk, it is the long term of the system storage device. If the hard disk may not be detected at startup, check the jumper setting. The jumper setting allows the mode of the hard disk master slave or vice versa. Make sure that the version Windows is used for partitioning is compatible. Verify that each station a type of disk is assigned. Make sure that the numbers of the axis of the connector are related to the pin of the socket. Not force the plug on the outlet with extra force, bending the pins can do. If the plug does not perfectly match the socket, please try again by it. Try not to open the disk hard without sufficient knowledge of the components.



Memory (RAM) random access

This is the temporary memory of the PC. The data in RAM are erased when the computer shuts down. Check if the RAM of the slit is moved. Check the modification of the RAM in the slot, the small niche in the middle of the chip (niche shows how RAM is supposed to be placed in the slot and may not be in the exact middle position of the chip Strip). Don't forget to check the side videos that the chip in place. If you are not able to be safe, it means that the chip is not well in the slot.



Disc compact-read only memory (Cd-rom) drive

Data stored on the external storage device, such as a compact disc (CD) are read by inserting the CD into the CD drive. If the CD-ROM drive does not work, check if the disk is striped. If the end CD in another PC, check the power of the old station cord. Check if the pin plug and socket numbers match. If the drive does not open, click the CD-ROM icon and select eject option. If the tray does not open, insert a straight pin on the border of thin metal and try to pull open. Not apply too much force while that to do so. Avoid the CD-ROM drive on the same cable of controller at the connection of the hard disk main, this will decrease performance.



Floppy disk drive

If the disk is not open, try to open it in another PC floppy drive. If the disk does not open, then it is probably damaged. If the disc is stuck in the drive, eject button for some time or right-click floppy drive icon and select eject option. If the disk is still blocked, stir the top and downwards until it can be ejected or use tweezers to withdraw from the market. Not apply too much force while that to do so.



To avoid any type of errors, after the maintenance tips can be followed:



* Do not leave any Saturate dust on the motherboard. Clean with a vacuum cleaner or broom a hand once every 2-3 months.

* Hard drive usually has not any external cleaners, although running disk fragmentation and clean, it can be prevented from crashing.

* In the case of the CD-ROM, do not pull the status bar under duress. To use the insert/eject button instead of pushing and drawing the status bar.

* Clean the tray from time to time. Do not leave a heavy object in the tray. Avoid of course scratched or damaged CD on the CD-ROM.

* If the CPU fan is making too much noise, disconnect and oil bearings.

* Try not to start the PC that the ventilation fan is not a condition.

* If the error persists, please contact professional services. Also take note of what happens exactly when you start the PC. It makes it much easier for the professional diagnosis.



CPU is the brain of your computer. Maintenance of the CPU and all other components improves the performance of the computer.
