The Windows operating system is the most widespread in the world. Millions of personal computers and server machines run this system. Software failures can paralyze entire businesses, and home PCs are no exception.
From the beginning of its development to the most recent releases, the OS has a built-in error reporting function. Each error consists of an alphanumeric code and a short description of the problem. All errors that have to be, are initialized by the system and are described on the official support site.
Most system errors tend to result in Blue Screen of Death (BSoD). Many users, when faced with an error called “blue screen of death”, think that this is a slang expression. This is actually a literal translation, and the acronym is approved by Microsoft itself.
One of the most common errors is a failure to initialize the hard disk of the computer, the error has the code – 0x0000007b… This is a typical stop – an error in the presence of which the system terminates working processes and requires a restart. In earlier versions of the OS, it was possible to restart the computer only manually or using hot keys. More modern versions include a timer and restart automatically.
Causes of the stop 0x0000007b system error
There are many reasons for signaling the system about the error of problems with HDD. We will try to identify and structure them all. Many consider the error only a system failure and do not attach importance to the technical component. But experience shows that a large number of problems are caused at the hardware level of building computers. From them, you can begin to list the possible failures in which there is error 0x0000007b.
1. Problems of connecting cables
One of the most common reasons for a system crash is a poor connection of signal data lines. This is especially true for the so-called work PCs, where hard drives are very often connected and replaced. This is true for servers as well. The terms of such use are subject to the segment where it is needed. An example is computers for video surveillance. The policy of their use often implies replacing hard drives when they are filled with the necessary information. A side effect is the loosening of the sockets of the connections of the loops, as a result of this violation of the contacts it is possible error 0x0000007b.
2. Power supply problem
Poor power supply to the hard drive may cause this failure. Over time, the power supply at extreme loads changes its output characteristics. This is due to the schematics of switching power supplies. Since at their output in the secondary circuits, electrolytic polar capacitors are installed. The electrolyte can dry out under moderate load. Therefore, there is a failure in the power delivered to consumers. Not receiving the necessary power for full operation, the hard disk of the computer can provoke the issuance of a system error message.
3. Loss of hard disk performance
Each HDD has a service life declared by the manufacturer. After using guaranteed performance, malfunctions are possible. The aging of magnetic disks can provoke the appearance of bad sectors. Such sectors are poorly readable or the access time to them increases. Disc kinematics are also subject to wear and, as a result, inaccurate positioning of the magnetic heads over the readable sectors.
The above reasons for the disk initialization error are hardware and are associated with technical malfunctions. Now about the issue of errors at the software level.
1. Error or missing driver
A driver is software whose purpose is to coordinate the electronic components of a computer with the services of the operating system that are responsible for connecting devices. BsoD error 0x0000007b may be caused by failures in the driver code or the lack of necessary files in its composition. By default on operating systems Windows device drivers are present, but legacy systems do not have new device drivers. In this case, the installation of the system may require a disc from the manufacturer with the software. For example, the error that occurs 0x0000007b windows XP is fairly common since the system no longer supports many hard drives.
2. Damage to the boot sector of the hard disk
The boot areas and service markup of the hard disk can be damaged. This happens due to incorrect user actions, but it can also be a consequence of the activity of viruses. MRB contains information about disk partitions, their format and structure. Damage to the boot areas causes the bootloader to be unable to catch the initial initialization. Such software corruption can cause blue screen 0x0000007b…
3. Incorrect configuration in BIOS
The BIOS of the computer provides several modes of operation of hard disks. The most common interface protocols are Standart IDE, AHSI, and RAID. The Standart IDE protocol is outdated, but almost all BIOS manufacturers have it installed by default. But today the most widespread is the Serial ATA interface, the higher speed of which provides work with the AHSI protocol. When installing a SATA hard disk, but using the IDE protocol, the disk will be emulated, and this will reduce the speed to the outdated Standard IDE norm. But the main problem is that if you install the system on the HDD in AHSI mode and then reset the BIOS settings to factory defaults, the error 0x0000007b will be initialized. Resetting the settings can occur both from incorrect user intervention and from a technical failure. It doesn’t matter how the settings were reset, the download error will be present. Connecting hard drives by the RAID type is not very common on consumer computers. This is an array of several hard drives that is used in server configurations, but the errors are relevant for them as well.
Methods and solutions for error 0x0000007b
In the order of presentation of the materials of the article, you can be guided by the same order as in the description of the causes of the error 0x0000007b.
- Poor connections are a common cause of failures in electronic devices. Computer systems are no exception. The presence of connecting loops and constant vibration of the system unit from the cooling fans can cause disruption of contacts. The problem is eliminated by replacing the connecting cables. The reliability of fixation in the connectors is checked, special attention is paid to plastic latches-latches. The looseness of the connectors themselves on the motherboard is checked. If there is a defect, and it is not possible to cope on your own, you should contact the service center to replace or solder the connectors.
- The output by the power supply unit of power lower than that declared by the manufacturer is solved by replacing the power supply itself. But you can also solve the problem by replacing the faulty elements. This requires certain knowledge in the field of electronics, and if there is none, resort to the help of specialists.
- Hardware failure of the hard drive requires replacement. Its malfunction can be roughly determined by the sound of an electric motor spinning. Sound, quite diagnosable, since the rotation speed is at least 7200 rpm. The lack of rotation or the presence of strong vibrations indicates a malfunction. Any sharp clicks of the hard drive indicate the fall of the magnetic heads or jamming of the kinematics. The problem is solved only by replacement.
Fixing initialization error 0x0000007b at the program level
- The missing or damaged driver files can be corrected by installing or replacing them. If Windows starts loading before the error appears, it makes sense to try to restore system files in safe mode. To do this, you need to press the F8 key at the very beginning of the download. In the menu for special boot methods, you need to select the “safe mode” option. The system will boot with only minimal configuration. You can restore the system by correcting the standard Windows tools through the “Start” menu. If the driver files are completely absent, you should install it from the manufacturer’s boot disk – this is relevant for old systems, where support for new hard drives is simply not provided due to their absence during the release of the system. Mistake 0x0000007b Windows 7 at boot systems does not always indicate the absence of a driver, since this system is supported by the manufacturer and the current drivers are added to the updates.
- Boot record recovery can be solved in several ways. You can try using the restore method to keep all settings and user files on a previously installed system. This action is provided by the installer interface. To do this, you need an installation flash drive or CD-ROM. Having booted to the window with a proposal to install Windows, you need to select the “Restore System” item. Although the name of the item may differ slightly in different versions of the system, the meaning remains the same. The installer will search for previously installed OS and offer to select the one you need. After the selection, the recovery process will begin, upon completion, a reboot will be performed and the entry into the operating mode will be performed.
- Another option is to check your hard drive for errors. The console is called from the initial window offering the installation of the operating system. This is done with the Shift and F10 keys. The chdsk command with the p and r keys will completely check the HDD and repair the bad sectors. A third party application can be used as well.
- The configuration setting of the hard disk in the BIOS must indicate the interface used by the computer. Depending on this, the mode is set to AHSI or Serial IDE. Almost all new drives use Serial ATA interface, and the AHSI mode is the most preferable one. This mode provides the speed of the hard drive. Different motherboard manufacturers have different BIOS entry keys. This information can be found in the instructions for the motherboard or on the manufacturer’s website. Stop error 0x0000007b Windows 7 at boot is often fixed by setting the correct configuration.
