A "Hardware Error" refers to a malfunction or failure in a physical component of a computer or electronic device. This can include issues with parts like the hard drive, RAM, motherboard, or power supply. Such errors can lead to system crashes, data loss, or the inability to start the device. These errors can be caused by various factors, including wear and tear, overheating, or manufacturing defects. Identifying a hardware error often requires diagnostic tools or tests, and resolving the issue may involve repairing or replacing the faulty component to restore proper functionality.
