Mechanical hard drives are destined to fail because of http://www.pcmech.com/article/hard-drive-failure-warnings-and-solutions/ all the moving parts that can go bad. SSDs can last a lot longer, but https://en.wikipedia.org/wiki/Power-on_self-test they also experience wear and tear that will ultimately require their replacement. With that in mind, we’re going to show you how to prepare for the worst by bringing to your attention the warnings you should look out for.Editor's Note: This article has been updated as of October 2016 with a bunch of new information and tips beep codes for properly diagnosing your hard drive.WarningsWith almost every component in your PC, you’ll see warning signs of a part going bad and in need of replacement. The hard drive is not an exception. Here are some signs to look out for:Disappearing files: Files can be lost do to mechanical problems with the disk itself, and in some cases, you’ll be able to tell as the disk usually makes some out-of-the-ordinary noises hp beep codes when things are going haywire.Computer freezing: A computer freezing is a common occurrence, and it’s almost always solved by a quick reboot. However, if you find that that it’s becoming more and more frequent, your hard drive could be on its last leg.Corrupted data: If you’ve downloaded and installed files without a hitch, but suddenly out of nowhere, files have become corrupt, it’s possible that your hard drive is experiencing a gradual failure.Bad sectors: A sector on a hard drive stores a certain amount of data accessible by the user. There are two types of sectors, a hard and soft sector. In most cases, Windows is able to repair a soft bad sector, as it’s almost always related to a software mishap. Formatting the drive will almost always fix this. But, if it’s a hard bad sector, this indicates physical damage, which can not be repaired. You can manually check for a bad sector by right-clicking the drive in My Computer. Select “Properties” and then navigate to the “Tools” tab. Finally, under “Error Checking” select the “Check” button. Windows will identify any sectors that have gone bad. As mentioned, Windows will try to fix it with a restart and doing some behind-the-scenes magic, but if that does not work, you could be, onc

Sometimes, it is shown 'Boot from CD'. (AMI BIOS) A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. This article mainly deals with personal computers, but many other embedded systems such as those in major appliances, avionics, communications, or medical equipment also have self-test routines which are automatically invoked at power-on. The results of tests run by the POST may be displayed on a panel that is part of the device, output to an external device, or stored for future retrieval by a diagnostic tool. Since a self-test might detect that the system's usual human-readable display is non-functional, an indicator lamp or a speaker may be provided to show error codes as a sequence of flashes or beeps. In addition to running tests, the POST process may also set the initial state of the device from firmware. In the case of a computer, the POST routines are part of a device's pre-boot sequence and only once they complete successfully is the bootstrap loader code invoked to load an operating system.
