Hardware Fault (Jack Headphone Socket)

This is a hardware fault because there is no sound coming out of any speakers of head phones this is because inside the slot there are little groves and once they touch the pins push down and transmit audio waves and after a lot of unplugging and plugging in the pins inside the stot get weaker and eventually will stop touching the jack

To fix this problem simply buy a new sound card for the computer and make sure that hard ware is compatible with your computer

Hardware & Software Faults (Blue Screen Of Death)

This is a hardware and software fault because your computer is stopping its self from getting damaged this is not very common any more but does still appear the causes of the blue screen of death could be a RAM problem or corrupt, missing or damaged .dll file and many more  

To fix this problem simply look for a KB Error code or look of the file which cause the fault in my case it was cause by SPCMDCON.SYS and this is a malicious program which generates fake warnings telling you that your computer is infected with viruses when it is not
 
I would recommend wiping the hard drive clean and reinstall the operating system which would be a lot faster and easier

Hardware & Human Fault (Dust)

This is a hardware and human fault because when you turn on a computer it sucks in all of the air and the dust around the tower and when the dust starts to build up inside the tower the computer is straining its self to keep it components cool enough so it does not overheat and it could cause damage to the components like the CPU which is the brain of the computer

This can be prevented by having your computer booked in at a technicians shop for a servicing or a clean inside the computer tower

Hardware & Human Faults (Laptop Battery)

This hardware fault because when the client turns on the computer it will boot up and after about 5 minutes it just turns off but when the power cable is plugged in is fine. This means that the laptops battery is not holding charge this can be caused by overcharging the battery

To fix this fault simply take out the battery and find the model number in something like eBay but make sure its brand new before you buy the product or go through the computers manufacture for example HP, SONY,DELL etc.

Human Faults (CD/DVD Drive)

This is a human fault because someone has flicked the band off the clog or either when people push the tray back in it makes the band slip and could cause it to come out of place. This is very common for business, schools and colleges to get the fault

To fix this fault simply open up the CD or DVD drive and put the band on the clog which it came off and then it should work

Hardware Fault (Mouse)

This is a hardware fault because the souse has stopped responding with the computer but the blue light is still on a the top mouse so the mouse has not gone to sleep mode but the red laser is not on so probably the laser inside the mouse has broken

To fix the fault simply replace the mouse with a working one and test the broken one in the other computer and it did not work so the laser has broken

Software Faults (File Type)

This is a software fault because the file which someone is trying to open won't open because the computer does not understand the file type for example this file is .rar and windows does not understand it to fix the problem simply download and install a compression software package which understands the extension name (.rar) which is free off the internet I used WinRAR which you can download off http://www.filehippo.com

Software Faults (Windows Media Player)

This is a software fault because the computer does not have the drivers for the soundcard to fix this problem simply insert the disk witch came with the product or download the software from the manufactures website.


Human Faults (Password)

This is a human fault because someone has forgotten there password to log on to the computer or Caps Lock is left on and the password is case sensitive.

This is very common for business, schools and colleges to get the fault because they have forgotten the password whilst on holiday because they have not needed to log on to the computer, to fix this problem simply log on to the local server locate the user and reset there password.

This is a human fault because someone has not set the printer up correctly on the network and the computer does not automatically connect to the printer because it is not visible on the network and an administrator of the network need to make the printer visible for the computers to find the network printer.

To connect to this printer you need to find out the IP Addresses of the printer and then go to devices and printer in control panel and select add printer and click on add network printer and select the printer that I want isn't listed type in the IP Address and click next until it says finish and you should be able to print. 

Hardware Faults (Keyboard)

This hardware fault because the keyboard is not responding to the computer whilst booting up, The USB connection is correctly inserted into the computer so just to make sure that the keyboard is broken get a working keyboard and plug it into the same computer and if it works the keyboard is broken.

Software Faults (Norton 360)

This is an Norton 360 Error 3048,3 this caused by Norton not getting the latest update on there virus/ spyware table to prevent people from infecting your computer. Norton 360 recommends that you go to there website and go to intelligent updater page and download and install the file and this should fix the problem.  

Software Faults (Norton 360)

Hardware Faults (SATA Cable)

This is a human fault because someone has not placed the SATA Cable into the motherboard correctly because half of the connection is not plugged in. This stops the computer from booting up correctly because it thinks that there is no operating system and the POST (Power On Self Test) kept repeating and looking for the hard drive

This can be done by replacing the hard drive and when plugging in the SATA Cable in to the motherboard and the hard drive and then nocking the cable which then becomes lose     

Also SATA stands for Serial Advanced Technology Attachment and it communicates between the CPU and the hard drive  



Hardware Faults (RAM)

This a human fault because someone has not placed the RAM correctly in to the motherboard which has stopped the computer from booting up. the computer

Also RAM stands for Random Access Memory and it stores information on what programs, applications and data that is being used on the computer so it can run

Hardware Faults (CMOS)


This a human fault because someone has placed the CMOS battry upside down which stops the computer from booting up correctly. In my case because it was upside down it stopped the graphics card from displaying an output the computer monitor
 
Also CMOS stands for Complementary Metal Oxide Semiconductor and it helps your computer to keep track of time whilst the computer is turned off.

Building A Computer From Scratch!

Below are some steps of me buliding a computer

CPU (Central Prossing Unit):
When placing the CPU on the motherboard make sure that the brown leaver is up and on the CUP there will be a pin missing make sure that the missing pin is lined up without a hole on the ZIF (Zero Insertion Force) socket



Hard Drive:
When placing the hard drive into the computer case make sure it is the right way up by making sure that the sockets are at the bottom and there twist the green locks so it will not fall out and the colour may vary in different cases



Inserting ATX Power Cable In To The Motherboard:
When placing the ATX Power cable into the motherboard make sure that you place the cable in the correct slot which is the slot next to the RAM slots which should be white slot



Computer Fully Built:
Once you have placed all of the components and connected all the components together put the side panel back on and then plug all of the cables in the back of the cable and then turn on the PC
