What causes computer slowdown?

Computer slowdown can be caused by a large variety of system-related problems, among them an outdated operating system, certain antivirus features, low disk memory, or background processes that use a lot of resources.

Sometimes, the slowdown can be caused by corrupted files that got into the system upon downloading or installing certain programs. It can happen even when working on a brand new computer or in a freshly installed operating system.

    1. Make sure to meet system requirements
    1. Check for the latest updates
    1. Check for conflicting programs
    1. Disable Hardware Graphic Acceleration

For instance, the Microsoft 365 suite needs the latest Windows 10 OS on a PC/laptop or one of the three latest versions of macOS, for a Mac.

Memory space should be at least 2 Gb RAM for 32-bit Windows or 4 Gb RAM for 64-bit Windows/ Mac. And the available hard disk space should be 4 Gb for PCs and 10 Gb for Macs.

Once you’ve made enough room for the bundle apps to function and you’ve updated the system, computer performance should improve.

2. Check for the latest updates

  • Open the Start menu > Settings app > Update & Security.
  • Click Check for updates.

Usually, Windows is updated automatically. But if any updates are missing, after the process is finished, your computer should resume normal functioning.

3. Check for conflicting programs

  • Type System Configuration in the taskbar and select Run as administrator.
  • On the Services tab, select Hide all Microsoft services, and then select Disable for all.
  • On the Startup tab, open Task Manager, and Disable all items.
  • Close the Task Manager and click OK in the System Configuration window.
  • Restart your device and reopen one of the Microsoft 365 programs to see if this helped.

A clean boot shows if any other installed program is interfering with the Microsoft 365 features so that you uninstall it or manage its functions.

Afterward, set your device to boot normally by opening the System Configuration as shown previously, and in the General tab, check Normal startup, then OK.

The Office 365 slowing down computer issue should be gone. If not, try out our last solution as well.

4. Disable Hardware Graphic Acceleration

  • In the File tab, click Options.
  • In the Options dialog box, click Advanced.
