Hi,
·
Have you made any changes to the computer prior to the issue?
Method 1:
Let’s run the performance troubleshooter and check if that helps. Refer the following link to run the troubleshooter.

Method 2: Change
the IRQ settings in the BIOS and check if that helps.
I would suggest you to uninstall the drivers for all the onboard devices that you can, shut down, reboot and then disable the
same onboard devices that use IRQs in the BIOS. Reboot and re-enable them in the BIOS one by one to see if the IRQs change. Obviously you can't disable any devices needed for booting, but floppy disk controller, audio, USB (assuming your mouse and keyboard
aren't USB) and Firewire controllers are good examples ones that can be disabled.
You may get in touch with the system manufacturer to get help for updating BIOS.
Warning:
Be careful when changing BIOS settings. The BIOS interface is designed for advanced users, and it's possible to change a setting that could prevent your computer from
starting correctly. Updating BIOS should only be done if necessary (to solve a compatibility problem, for example). It can be a complicated process, and if an error occurs, your computer could be rendered inoperable. Be sure to follow the manufacturer's instructions
exactly.
