During the Windows startup process, the computer may stop responding (hang), and you may receive the following error message: *** Hardware Malfunction Call your hardware vendor for support *** The system has halted *** One of the following error messages may also be included: NMI: Parity Check / Memory Parity Error NMI: Channel Check / IOCHK NMI: Fail-safe timer NMI: Bus Timeout NMI: Software NMI generated NMI: Eisa IOCHKERR board x This behavior can occur if a hardware…show more content…
When the read/write head touches the rotating platter of a hard disk, it leads to head crash. When even the smallest bit of dust enters the sealed drive unit and settles on magnetic surfaces, it gets stuck in the thin gap between the head and the disk. Dropping a disk to the floor may also cause hard disk malfunction. Not only this, even the slight jerk or vibration can unsettle alignments and lead to hardware malfunction. (b) Sudden catastrophic failure: When you cannot detect the presence of the hard drive in the CMOS setup or when the operating system doesn’t locate the hard drive, it’s logical to think that the data loss has occurred. This POST failure results in hard drive to become inactive. This is when you hear the clicking noise from the hard drive. Sudden temperature variations may directly influence the data loss to occur. (c) Electrical Failure: Another issue ultimately resulting in the loss of information is electrical failure, which can occur any time. Electrical failure is the direct effect of the circuit board failure, which is located on the bottom of the hard drive. A faulty component, electro-static discharge, damaging circuitry during installation are some of the various causes leading to electrical failure. It is important to keep the system clean and well ventilated; otherwise, it may cause electrical components to fail functioning properly. Hence, it is recommended to keep the system in cool
