Reboot your computer

A full reboot is the first thing you always do with a Windows PC. Rebooting can often fix many issues leaving you safe to carry on your day.

Scratched Media / Damaged USB Drives

If you are trying to install something when the error occurs, try different installation media. Download the program or game again or acquire a different copy of CD or DVD if you?re going old school.

Check all cabling inside your PC (May Void Warranty)

Cables can have wear and tear, checking cabling could resolve issues resulting in saving a lot of money. If you are inexperienced I do not recommend opening your computer, however if you are feeling confident about it then checking cabling is seated correctly and not damaged could resolve your issues.

Update your drivers

You may be using Vendor provided drivers such as Dell, or you may just have the default Windows drivers that Microsoft installs during a Windows installation.

We recommend looking at your manufacturers website for updated drivers or if it is a custom build PC then accessing the websites for the manufacturers individual parts are recommended.


To run chkdsk type CMD into the Windows Search box. Right click the menu item and select Open as administrator. Type ?chkdsk /f /r C:?. If it isn?t your C: drive giving the error, change ?C:? to the drive letter in question.

Windows will then run a scan to check for errors and bad sectors. There are other commands instead of f or r such as:

/f option will attempt to fix any found errors

/r option will locate for bad sectors and recovery any readable information

/x option will force the volume you?re about to check to be dismounted before the utility begins a scan


SFC, or System File Checker is an internal integrity checker within Windows 10. Within CMD window you used above, type ?sfc /scannow? and hit Enter.

This will check Windows for damage or corruption and will automatically fix anything it finds.

Remove all peripherals

USB drives can draw a limited mount of power. ?If you use too many it can cause error 0xc00000e9 in Windows. If you do have to use peripherals, remove them and see if the error goes away. You can try reconnecting one at a time until the error returns, this can help you identify the culprit.
