how to repair computers

We will discuss about how to repair computers . If the PC is often times show an error in the computer , or display an error message , emits a continuous beep is regular or irregular , PC likely is in trouble , I will provide tips and solutions to overcome these problems and your PC can function again as usual . Problems or damage arising usually categorized in two types of damage , namely : Problems or damage Hardware and Software

Damage Type Can be categorized into 2 categories , namely :
1 . Damage Hardware ( Hardware )
2 . Damage On Software ( Software )

1 . Damage to Hardware
Problems with hardware components need serious treatment because it is difficult to locate and removed without proper tools , expertise and support experience . Explanation will revolve around the problems that often occur along with how to cope.

Damage In Power Supply
symptoms :
When turned on the PC does not react to anything , there is no display on the monitor , there is no indicator light ( LED) is lit , the power supply fan is not spinning , the indicator light does not turn on the monitor .
solution :
Check whether the cable is properly connected and installed the plug into the socket , check whether there is the on / off behind exactly behind the Power Supply is in the On position , If you are sure installed correctly but still no response to ensure you please replace the power cord with which you believe to be good . The problem occurs in the absence of incoming voltage , damage to the power cable .
problem :
When turned on the PC does not react to anything , there is no display on the monitor , there is no indicator light ( LED) is lit , the power supply fan is not spinning , the indicator light on the monitor .
solution :
Do it like a step above , but if there is still no response means there is a problem in Power Supply , PS Please change it , I suggest you should just replace the damaged Power Supply with a new one , and be careful in the installation.
Note : If the damage is only on the Power Supply alone , When you replace it , the computer will continue to work normally . Unless there is a problem in other components such as Mother Board , VGA Card and Memory .

Damage On Mother Board
symptoms :
Once turned on , there is no display on the monitor , the indicator light ( LED ) on the front panel is lit , the indicator light ( LED ) flashing monitors , power supply fan and the processor fan spins , no beep sound on the speakers .
solution :
The first step disconnect all power cables are connected to the electrical , data cable to the monitor , cable keyboard / mouse , and all cables are connected to the CPU , and then remove all the screws cashing cover . In an open case please also remove other components , the voltage of the power supply cable is connected to the motherboard , hard drive , floppy , be careful in the process do not be in a hurry . So is the card attached to the Motherboard ( VGA , Sound Card or other ) . Now attached to the motherboard just cashing it . Please check carefully at computer Motherboard , see Chip ( IC ) , transistor and others if there is a fire .
If there are no signs of burnt components Motherboard chances are still good , but there are times when Mother board does not work because of damage to the programs contained in the BIOS
symptoms :
By the time the CPU is turned on and then did post after the process does not continue , and was silent for a moment does not go directly to the operating system , and then the screen is the message " disk error, disk Failure , after it appeared the message " press F1 to continue " after we pressing the F1 key does not enter operating system and the message " Operating system not found " .

Damage Hard Drive
solution :
Check the voltage cable and a data cable that goes to the hard drive is loose , should be tightened , then turn it on and let you listen to what came out of the disk normal , if not normal means damaged hard drive controller .
symptoms :
By the time the CPU is turned on and then did post after it appeared the message " Operating system not found " .
solution :
There is the possibility of operating system is damaged , can be overcome by reinstalling or if you are using Windows 2000/XP OS there repair computer facilities . or there is also the possibility of your hard drive is not detected and return
symptoms :
hard disk bad sectors ?
solution :
There are several factors that cause bad sectors such occurs , the voltage is unstable , power failures often occur suddenly , after used that not shot down , consumption is too long , there are two types of bad sectors are physical and software ..... To overcome some ways , including using software to eliminate BadSector. of change in more eBooks in repair computer methods and what you get if you join the Active Member .

Damage CD / DVD / ROM / RW & Floppy Disk
symptoms :
Types of damage are commonly encountered :
1 . Not detected in windows
2 . Can not go out CD
3 . Can not read / write / can only read it . ( CD )
4 . Can not read / write / write protect ( Floppy disk )
solution :
1 . Check the data cable and voltage cable into the CD - floppy, check in bios setup if it detected ? should be set to auto . Check if the light is on , if not damage the controller .
2 . Mechanical damage on the rubber motor or motors .
3 . Usually the optical damage , but there may still be improved in a way to set the repeat for optical .
4 . Dirty Head , can be cleaned using cotton ( above steps are complete can be found in the e -book " method of computer repair fast and accurate " and what you get if you join a member at this blog.

BIOS problems
symptoms :
Be careful in Bios Update , as he got the wrong update your Bios version , not the PC so you can not even get into the BIOS .
solution :
Updates usually can not be canceled , only certain types of motherboards have a backup BIOS chip it in , there is saved the original BIOS types that can not be removed , to be able to restore your stay special move Jumper position that usually have no clue on the manuals . Then turn on computer and wait 10 seconds , the original BIOS in Restore , restore Jumper position to its original position , and the PC is ready to run again . If the motherboard does not have facility , the BIOS chip must be sent to the manufacturer , type your BIOS can see in the manuals . Be careful not to install the BIOS IC legs broken or inverted position .
symptoms :
CPU Beep sound in the speaker several times and there is no display on the screen , when the monitor is not problematic .
solution :
Beep Beep indicates a particular error message from the BIOS , it shows the type error Beep what happens on the computer , usually an error on non-detectable Memory , VGA card , which is not installed properly , even Processor Monitor data cable could be the cause . Please check the problem.

Following BIOS error message :
Beep error Motherboard BIOS usually not all signify the same error depends on the type of its BIOS .
[ AMI BIOS ]
Beep 1x : RAM / Memory not installed or Damaged Good , Beep 6x : Error Gate A20 - Indicates damaged or IC Keyboard Gate A20 of his own , Beep 8x : Card Graphic
/ VGA Card is not installed properly or damaged , Beep 11x : checksum Error , check the Bios chip , and replace it with a new one .
[ AWARD BIOS ]
Beep 1x Length : RAM / Memory not installed or Damaged Good , Beep 1x 2x Short Term : Damage In Graphic Card ( VGA ) , Check the installation could also not fit in the slot ( not entered ) , Beep 1x 3x Long Short : Keyboard broken or not installed . No beep interrupted / continuous sound : RAM or Graphic Card not detected .
battery CMOS Damage / Weak
Symptoms : Appear message CMOS checksum Failure / battery Low , due the power which to supply IC CMOS / BIOS is not normal because battery
 weak , so the BIOS settings back to factory default for setting , and hardware configurations must be in Reset .
Solution : Replace Soon his batrey
Symptoms: The CPU is often Hang ?
Solution : There are several factors going on hanging them : There BadSector in Hard Drive, There viruses , such as the problem in the Hardware Memory Dirty / Damaged , Mboard Dirty / Damaged , Fan Cooling fan rotation was already weak , unstable ..... Power Supply should not be forced to be used because it will result in more fatal , please contact: us to be able to resolve the issue
Symptoms often appear blue computer screen what causes it ?
Solution : Blue Screen message can be caused by Windows system are damaged , Can of Memory , Can the hard drive , can be from other components , depending on the blue screen messages are displayed .
Symptoms : Computers become slower than before , but not so slow initially
Solution : The cause of your computer slow process there are several factors: Space hard drive is too full , too many programs / software are consuming disk space and memory , no viruses , hard drive BadSector .
