Dust ages the components of the computer and slows down the running of the hardware.

Besides, the dust in some slots can also result in mouse and keyboard not working, graphics not showing, Windows 10 DRIVER_IRQL_NOT_LESS_OR_EQUAL error, etc. So clean the dust out of you desktop regularly with a brush or a blower, and then power on the device to see if it speeds up the boot time.

Method 2: Manage Files or Shortcuts on the C Drive

Computer startups are loaded from the C drive every time you boot the device. If there are too many programs on the C drive, Windows 10 will take a long period to load the startups, which slows down the PC booting.

Kill off your icons or shortcuts on the desktop and remove the files from the C drive that are seldom used. This will avoid the long pre-loading of the shortcuts when you reboot the computer.

2. Install Software on Other Disk Drives

If there are large sizes of programs or software installed on the C drive, the memory room will be occupied and the slow boot issue will occur. So install or reinstall those programs on other drives. This will protect your important data once you have to reinstall the Windows as well as speed up the PC booting.
