Final work about testing

[Matiasqooo]

Hello guys

I am an student in "RVT" trying to get a certificate in IT technician. One of my works for now is to make a essay about each part of pc and how to test it, troubleshoot and stress test. Now I need to make a table full of possible defects for each component and how that was introduced and how to get rid of it, for an example for GPU - blown caps, miss handling, manufacturing problem, burned dye from over volting, damaged power connector, snapped pcb, GPU not detected by windows, can see artefacts on screen, not running on all possible speed, crashed windows and so the list goes on and on.

so can you help me and cal all posible defects for - CPU, Motherboard, GPU, RAM, PSU, HHD, SSD, SSHD and CD-ROM

my work as far as it is for now (it is in Latvian) - https://drive.google.com/file/d/0B_VN1fzhcq6CQjItRlM3OG85M1U/view?usp=sharing

gpu:
temp

voltage

capacitor

bad motherboard

physical damage

water damage

bad vram

bad gpu (die, eg G104)

power surge

bad power input (unstable)

 

cpu:

temp

voltage

bad motherboard (fried cpu)

physical damage

bad die

power surge

bad power input

 

motherboard:
bad PCB tracings

bad capacitors

water damage

thanks for this and i also need defect things that some basic home user could see like blue screened pc or crashed when trying to connect to network  (LAN card also needed) or when playing games the pc freezes (that is cpu) more is like - can see artefacts on screen (GPU)

Well, it's quite insane to document everything but anyway, i got some suggestions

 

cd-rom:

broken laser

damaged laser (scratches for example)

dusty laser

broken motor (cd doesn't spin)

gearing broken (doesn't open or close)

No power

Wrong laser (blu-ray cd can't be read by a dvd reader, more of a user error tbh)

 

hdd:

weird noises

random freezes

corrupted files

broken motor

hdd unreadable due to physcial damage by the read/write head (scratches)

broken due to user dropping it. (more common than you might think)

 

psu:

burned down house, obviously

Jokes aside, it is a possibility a house actually burns down due to a bad psu.

Human death, also possible, the thing can short out and if a human was touching the case at that point it's possible the short kills the person.

Or you are stupid, open the psu and short out the cap, if the cap is still charged it could release a deadly shock.

 

PSU's are dangerous things and by far the most scary part of a PC. You might think it's fine when it's unplugged but actually to keep it simple, usually there's some electricity hidden in it ready to leap out and shock you to death.

Honestly, just a handful of examples of every pc component should do it.

The thing is that you can't document everything.

Sometimes the solution doesn't even make sense for some problems.
