Hello guyz… I need a bit of your help

Can you give me one example of a computer fault that could be caused by

  • A dusty Atmosphere ?
  • Excessive Vibration
  • Excessive Heat
  • Magnetic Heat such as that caused by fax machines or speakers…

Basically i am doing this assignment and this is the question i am stuck on, i have done most of it but for these four i can’t really think of an answer. For a dusty atmosphere, the Pc is likely to slow down ? or some parts might stop working in the CPU ? Am i right ? And for excessive heat the fault is likely that the cooling fan will stop working in CPU ?

Erm… i kind of know the answers but just to want to add in as much as i can, that’s why i am asking you, help will be appreciated…

Thanks : )

A dusty Atmosphere - Dust buildup inside, leading to increasing temp, could cause unstability of the OS, could lead to CPU fan not spinning, could lead to CPU burning out or repeated crashes (if the CPU has some burnout protection).

Excessive Vibration - Not sure on this one, but 'Excessive' vibrations could cause the hard drive heads to hit the platters, leading to data loss, corruption. maybe a CPU cooler/fan can pop off, again leading to CPU burnout or repeated crashes (if the CPU has some burnout protection).

Excessive heat - see above

Magnetic heat - what is that? If it is magnetism, it can cause data loss.

The last one should really be Magnetic interference and not heat. More specifically, EMI causes noise issues. There are several components on the mother board, specifically those using timing high frequency crystals/oscillators that can be affected by EMI and ground bounce. Once the ticks are affected, the sub-system wont work properly, or will be intermittant/erratic. As a designer, one has to be very careful when it comes to routing, placement, and EMI shielding to prevent such things. In short proper screening, earthing, and shielding prevents EMI.

Excessive vibration can also cause the crystal oscillator to fail. It can also lead to micro fractures of traces in the internal layers of the PCB of the motherboard. Once you have extremely fine traces in an internal layer where the continuity breaks, your motherboard is a waste, and could be used as an expensive paper weight.
