I don't think that commenting on Donald Trump would be the cause in this case.
Ram
chassis or case ground Another name for computer ground could also be zero, referring to computer electronic circuits using combinations of high and low voltages. Low voltages or absence of voltage (zero) is also referred to as ground.
The ground prong is connected to the computer chassis, including the outside of the power supply module. This is a safety feature to ensure that the metal case of the computer and power supply never becomes dangerously electrified in the event of a loose wire. Modifying the power cord not to have a ground prong would violate electrical codes intended to prevent accidental electrocution. That said, the ground prong is not essential for the normal operation of the computer, and the computer will still function without it. Proceed at your own risk.
It will not typically harm the computer itself, if it is a case screw. But it may cause the case to bend or fall off over time.
If there is not a fan,or ventilation in your tower case then overheating can occur.
Because of energy and the different components
Bad PSU, (power supply). Did not install motherboard right in case, and bad ground.
many things
PRESUMING you have already unplugged it and removed the cover, ground yourself by attaching a grounding strap to your wrist and the computer case to prevent static discharge
Theoretically any computer case made in the last several years or later. The choice of computer cases depends on personal preference. Some are designed to be quiet, some have many hard-drive slots, some are built to look cool, but in general any recent computer case would work. All motherboards and other computer hardware are designed to fit any computer case, and if the computer case requires any case-specific hardware it comes with the case.
