Problems of installation of hardware
- 1. Potential Problems of the installation of computer hardware By George Smith-Moore
- 2. Potential Problems O The potential problems that could occur when installing computer hardware can be numerous. But the most common are… O Component Damage O Loss of Data O Not Compatible
- 3. Component Damage! O This is one of the biggest forms of computer component damage. The damage can come from many things, such as: electrostatic discharge and incorrect installation. O Electrostatic discharge is a big ‘killer’ of computer components, it can be done by not wearing anti- static equipment. O Incorrect installation would usually damage the connectors, this would be placing a cable or component in the wrong socket; for example.
- 4. Loss of Data O By installing a piece of hardware incorrectly you could damage the component, this could mean that the data inside could be lost. O An example would be when a hard-drive is being transferred to another machine; this is why you should back-up all data.
- 5. Not Compatible O A device not being compatible with the system is a big problem; for instance you may have a DDR2 motherboard but DDR3 RAM. There is a difference and so it is not compatible with each other. O Another example is: an PCIe x16 graphics card; you may not have the slot to accommodate this (a PCIe x1 slot will not work).
