Method 1: SuperFetch must be disabled

SuperFetch shortens boot time to make program loading even more efficient. But SuperFetch is identified as a potential cause of problems in Windows. 

You can stop the service as follows:

  • Press the Windows logo key on your keyboard – type command line – select “Run as administrator.”
  • Go to User Account Control, where you click “Yes.”
  • Command Prompt appears again – enter the command “net.exe stop superfetch” – press Enter.
  • The command “net.exe stop superfetch” is invalid? Replace it with the command “net.exe stop sysmain.”
  • Test your PC after a few minutes. Maybe its performance has improved. 
  • You can also check your PC’s performance as follows: Go to “Task Manager” in the Windows search engine – click on the “Processes” tab – at the top of the “Disk” tab, the percentage should show less than 100%.

Method 2: Try updating your device drivers

If Method 1 could not solve the error, the problem may be in the device drivers. Driver Easy can automatically update each driver to the latest version.

Driver Easy knows how to automatically detect the system and find the necessary drivers without any errors. 

  • Download Driver Easy and install the program. 
  • Launch the program – click Scan Now – the program will find the problem drivers.
  • Click Update next to any marked device – will automatically download and install the correct version of the selected driver.
  • You can also click Update All – it will automatically download and install the correct drivers.
  • Now let’s check the PC disk usage. Type “task manager” in the Windows search bar – then go to “Task Manager” – select the “Processes” tab – look at the percentage in the “Disk” column. The rate should show less than 100%.

Method 3: Disk check

  • Press the Windows and X key on your keyboard – select Command Prompt (Admin). 
  • Press Yes at “User Account Control.” 
  • A command line will appear in front of you – type the command “chkdsk.exe /f /r” there.
  • Close all applications – hit Enter – type Y – disk check, and restart of PC will start. 

BY THE WAY: The disk check starts after your PC reboots. This procedure takes a certain amount of time.

  • The disk check is complete. Now let’s check the disk usage on your computer: Type “task manager” in the Windows search bar – then go to “Task Manager” – select the “Processes” tab – look at the percentage in the “Disk” column. The rate should show less than 100%.

Method 4: Virtual memory needs to be reset

Virtual memory is an extension of your PC’s physical memory. If there is not enough RAM, Windows will store files in virtual memory for some time. 

To reset virtual memory, do the following steps:

  • On your keyboard, simultaneously press Windows + Pause/ Break. Then select “Advanced System Settings” on the left panel.
  • On the “Advanced System Settings” tab, click on “Settings.” 
  • Once again, go to “Advanced” and select “Change” under Virtual Memory. 
  • The Automatically manage paging file size for all drives checkbox should be unchecked. 
  • Select the Windows drive (the place where Windows is installed) – enter the initial size + the virtual memory’s maximum size – then click Install and then OK. 
  • Need to clear all “temp” files: press Windows and R keys simultaneously – type temp in “Run” form – press Enter. Now the Temp folder should open, where all temporary files will appear. 
  • Search file in the Temp folder – now just delete them. 
  • You can also check your PC’s performance as follows: Go to “Task Manager” in the Windows search engine – click on the “Processes” tab – at the top of the “Disk” tab, the percentage should show less than 100%.

Method 5: Disable antivirus software for a while

Various antivirus programs (Norton, Kaspersky, AVG, Avast Behavior Shield, Malwarebytes, etc.) need to be disabled for a while to ensure that they do not cause problems on your PC. 

Each program is disabled in its settings.

By the way, Microsoft has its antivirus software – Windows Defender. This program automatically starts even when other antivirus programs are installed.

Once the antivirus is disabled, check the disk usage on your PC: Go to “Task Manager” in the Windows search engine – click on the “Processes” tab – at the top of the “Disk” tab, the percentage should show less than 100%.

Method 6: The StorAHCI.sys driver needs to be fixed

The problem is often caused by several PCI-Express (AHCI PCIe) models, which have an Advanced Host Controller Interface and the inbox StorAHCI.sys driver is running due to a bug in the firmware. 

Correcting the problem:

  • Open Device Manager. 
  • Expand the IDE ATA/ATAPI Controllers category – double click on the AHCI controller. 
  • Go to the Driver tab – click Driver Details. If the storahci.sys file is in the path to the system32 folder. Then it would be best if you ran the incoming AHCI controller driver. 
  • Close the Driver Details window – go to the Details tab – a menu will appear where you need to select the Device Instance Path. Now you need to write down the path, starting with VEN_. 
  • Type Regedit in the Start panel’s search box – press Enter – launches Registry Editor. Next, go to: 

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\PCI\ <AHCI Controller>\<Random Number>\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties.

Here <AHCI Controller> leads to the name that was in the IDE ATA/ATAPI Controllers category. 

  • Double click on the MSISupported key – change the value to 0. 
  • The PC needs to reboot. Now you can also check your PC’s performance as follows: Go to “Task Manager” in the Windows search engine – click on the “Processes” tab – at the top of the “Disk” tab, the percentage should show less than 100%.
