Hello,

To fix high CPU usage issue, please refer these steps:

Try to identify the process creating this issue.

Download Process Explorer from Microsoft:

Process Explorer - Windows Sysinternals

Run the tool then select the system process, right-click and select Properties.

Switch to the Threads tab. This will show which file is using the excessive CPU usage, from which you can then attempt to diagnose it.

Windows 10 100% Disk Usage on startup.

Hi,

Thank you for responding.

I suggest you to try the below steps and check if it helps.

Step 1: First of all, take a note of the processes or applications that is running when the computer runs with high disk usage. Also, we need to find the applications that are running at startup.

Follow the steps to check for the processes under Task Manager:

• Press Ctrl+Shift+Esc to open Task Manager.
  
• Click on Processes tab. Check if any of the processes consumes high memory usage.

Bad sectors on the hard drive can be a cause for high disk usage.

Check which process is utilizing the Hard Disk on Windows 8.1, you may try the following steps.

• Open Task Manager and click on
  Details tab.
• Right click the columns headers and click "Select Columns".
• From the "Select Columns" window, check: I/O Reads, I/O Writes, I/O read bytes, I/O write bytes and then click
  OK.
• Now the columns will be added to the view and will display how much each process is utilizing from the hard disk.
• Sort by I/O read bytes or I/O write bytes by clicking on the column header to see which process is utilizing the Hard Drive most.

Step 2: If you have not run the 'check disk' scan or tried optimizing the drive, follow the steps from this article.

(Note: This applies to Windows 10 also.)

Important: While performing check disk on the hard drive, if any bad sectors are found on the hard drive, it tries to repair that sector and any data available on that might be lost.
