Many people are not familiar with the ins and outs of computer hardware and so may be hesitant to ever open up their computer and start fiddling with its internal components. While it may seem intimidating, it is actually fairly easy to open up a computer to replace a part or perform an upgrade, so long as you are careful. To answer the question, the best time to touch the inside of a computer is when it is turned off.
Before proceeding, you should make sure to unplug your computer from the power outlet. It is also a good idea to touch an object that is grounded (eg a metal object such as a chair) before touching the inside of the computer, as this will disperse any static electricity that may have built up. Once this is done, you can open up the computer case to get started.
The first step is to examine the inside of the computer. Make sure not to touch any of the components or the motherboard while the computer is turned off and unplugged. This is important because any static electricity could potentially damage the delicate components inside the computer.
Now that you have examined the inside of the computer, you can begin unscrewing and loosening the computer casing. Be sure to use caution here, as it is easy to accidentally break a component while working in the tight confines of the computer casing. Take your time and pay attention to where the screws are, and try to remember which slots they fit back into.
While you are working on the computer, it is important to use proper tools. Screwdrivers of different shapes and sizes can be used to unscrew the computer casing and loosen any components. It is also essential to use the correct type of screwdriver for the type of screws used inside the computer; otherwise you risk damaging the components.
Once you have replaced the part or upgraded your system, it is important to properly screw the casing back into place. This will ensure that the components remain secure and will prevent dust from entering and damaging the components inside.
Finally, make sure to switch off the power and plug the computer back into the power outlet. Once the computer has been turned off, it is safe to touch the inside of the computer components.
In summary, it is okay to touch the inside of a computer that is turned on, but only after you have taken the necessary precautions and unplugged the computer from the power outlet. Before touching any of the components inside the computer, be sure to touch a grounded object such as a metal chair to disperse any static electricity. Make sure to use proper tools and take your time when working inside the computer and remember to properly screw the casing back into place when you are finished.
