What are some exceptions to the rule of always being grounded when you work with PCs?
When working inside a monitor, inside a power supply or inside another high voltage peripheral such as a laser printer or scanner. The reason is that these components contain a powerful electrical charge even after they are disconnected from power. You don't want to be grounded because you provide yourself as a conduit for the voltage to discharge through, which would suck.
Which device you should use to prevent the effects of fluctuation in the power supply on your PC and to continue to work for a specific time even if there is no power?

What will happen if my computer power supply's fan stop working?
The electronics inside of the power supply will overheat and cause the power supply to quit working. There might even be a small fire inside, or the semiconductors may crack or explode. So it is best to repair or replace the power supply when the fan starts to malfunction, since it will be easier to fix. If you must operate it that way, you should take steps to reduce power consumption and make sure the fan is running each time. Some even insert things in there to start the fan if it is stalled, though that has its risks.
