o The system is infected with malware. To prevent this, run full antimalware scans on a regular basis. o The system has inadequate memory installed. If this is the case, add more memory to the system. o The system has inadequate video hardware. Avoid using integrated video adapters. A video adapter board with adequate video memory will perform much better. o The page file configuration has not been optimized. You can improve performance by moving the page file to a disk other than the system disk. Creating page files on multiple storage devices can also increase system performance. o The hard disk is overly full and heavily fragmented. Upgrade to a bigger disk and keep it defragged regularly. o There are unnecessary applications being loaded at system startup. Use Task Manager turn off startup applications that aren't used frequently. Uninstall applications on the system that aren't needed. If you have a specific application that stops responding, you can use Task Manager to end or stop the application. Be aware that you might lose any data generated by the application. Spontaneous reboot can be caused by a bad power supply, device driver, or an overheated CPU. Intermittent system crashes without any other apparent cause can be caused by overheated components.

A noisy fan might be caused by something rubbing on the fan (such as a cable inside the case). If there is nothing touching the fan, then the bearings could be going bad. Replace the fan before it stops working. A clicking noise when reading or writing data from the hard disk is an early sign of a failing drive. Move data from the drive as soon as possible. A blue screen error that continually references the same memory address could indicate memory that is starting to fail. If an error message indicates that a DLL file associated with an application is corrupt or missing, do one of the following: o Manually copy a known-good copy of the DLL back into the appropriate location in the file system. o Repair the installation (if possible) using the application installer. o Uninstall the application and then reinstall it. o Restore the system to a prior restore point. If an error message indicates that an operating system DLL file is corrupt or missing, do one of the following: o Manually copy a known-good copy of the DLL back into the appropriate location in the file system. o Restore the system to a prior restore point. o Run the system file checker utility from the command prompt. The command is sfc /scannow . This utility scans all system files and replaces missing, corrupt, or incorrect versions of these files.

    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.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
