Possible Causes of System Lockups 1:55-2:18 Let's review some of the common causes of system lockups. This list is not all inclusive. There are literally thousands of possible causes for a lockup. The exact cause is heavily dependent on the version of Windows you're using, the hardware installed in the system, the device drivers in use, and the applications that have been installed. We'll limit this lesson to a discussion of several common causes of system lockups. Software Errors 2:19-2:50 First, a system lockup could be caused by a software error, such as software bugs. Software bugs are poorly written operating system files, applications, or device drivers that can cause a system lockup. A corrupt system file can also cause a system lockup. A corrupt system file can be caused by an unclean shut down, a failing storage device, or even malware. If a lockup occurs every time a particular application is run, or a hardware device is used, then it could be due to a bug in a software somewhere. Overheated Hardware 2:51-3:10 Another possible cause is overheated hardware. If the processor, a memory module, or a storage device gets too hot, it could cause the system to lockup. Some systems are equipped with a thermal protection feature that automatically shuts the system off if a temperature threshold is exceeded.However, other systems do not. Failing Hardware 3:11-3:44

It's also possible that a system lockup could be caused by failing system hardware. For example, this can happen if a hard drive is failing. Remember, hard drives are mechanical drives that wear out over time. A hard disk with bad sectors or malfunctioning components can cause a system lockup. A system lockup can also be caused by a failing memory module. For example, a module may have been mishandled or exposed to ESD. When this happens, some memory locations on the module may be damaged. When the system attempts to read or write data to those locations, the system locks up. Preventative Measures 3:45-4:20 When lockups occur, it is your responsibility as a PC technician to isolate the cause and fix it if possible. Usually, it's easier to prevent a lockup than to troubleshoot them. Some preventative measures you can take include installing the latest operating system updates, installing the latest device driver updates, and installing the latest application updates. These measures will help prevent lockups caused by software errors. You can also use the system file checker, SFC Utility, to verify the integrity of your system files. If it finds a corrupt system file, this tool can replace it with a known good copy. Using Web Resources 4:21-4:47 If a lockup occurs in spite of these measures, you can use a variety of web resources to troubleshoot the issue. For example, if the system locks up and you see a Windows blue screen error message displayed, capture the error message and/or number. Then, search the web for information about that error. Most likely, someone else has already experienced the same problem, and a resolutionmay already exist. For example, a hotfix may have been released to fix the problem.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
