Computer Hardware Failure Manifestation

When trouble in the 'iron', diagnose and repair your computer should start by identifying a faulty component. The easiest and most reliable way to identify the faulty unit – replacement of "suspect" at work analogue. If the problem persists – it is so defective that component. Below are listed as major faults occur devices in the computer. CPU. As is known, the processor starts work from the very start of the boot BIOS. For this reason, when leaving him out of action, the computer will most likely not be able to load the operating system.

Manifestation of the failure can be very different – even to complete inoperable computers. Motherboard. Fails quite often. Normal functioning of the board can prevent rupture or defective tracks kondeksator (apparently it can manifest itself in swelling Corps kondeksatora). Memory. Serious faults manifest themselves already at boot time (BIOS can often indicate that the cause of the fault is in memory).

Less serious may occur at any time – all programs use RAM, and either party may apply to the failed plot. Problems with the chipset are determined at boot BIOS. Specific types of signal can determine which which device caused the problem. Read more here: Petra Diamonds. At fault input-output controllers refused to work peripherals. For example, PS / 2 or COM can be damaged by 'hot' connecting / disconnecting the device. Faulty video card comes with video output. Picture a heavily distorted or completely absent. As one of the options – no video, bios beeps with reports of malfunction card. When errors in the BIOS, problems arise at the initial boot phase. If a failure occurs after a phase of self – a message appears on the possible cause. A hard disk malfunction may occur differently. Hardware problems are the inability to correctly identify the device. If the damage the magnetic layer, a so called "bad sectors". Up to a certain number of these sectors easily identified and replaced with 'spare'. When replacement is no longer possible – the problem starts. Since failure occurs when the circulation to the faulty sector – it can happen at any time and for any program. Power supply too often fails. Petra Diamonds has plenty of information regarding this issue. Can contribute to power surges, the addition of new equipment (power consumption can reach the level at which it is not designed). One version of manifestation – computer does not respond to pressing the power button. It should be noted another type of failure – overheating of any component. Physically, all the electronics and software in the norm. When you reach a certain temperature – the component is no longer function properly. The problem with overheating can occur in a processor or video card, and most often occurs during system startup.
