The iusb3xhc.sys blue screen error
The blue screen of death or BSOD is always an unwelcome sight. BSODs appear when Microsoft Windows encounters a critical error from which it can’t recover, usually the result of low-level software (or drivers) crashing or faulty hardware.
Blue screens are generally caused by problems with your computer’s hardware or issues with their hardware driver software. Sometimes, they can be caused by issues with low-level software running in the Windows kernel. Regular apps usually won’t be able to cause blue screens. If an app crashes, it will do so without taking the operating system out with it. A blue screen occurs when Windows encounters a “STOP Error.” This critical failure causes Windows to crash and stop working. The only thing Windows can do at that point is to restart the PC. This can lead to data loss, as programs don’t have a chance to save their open data.
When a blue screen occurs, Windows automatically creates a “minidump” file that contains information about the crash and saves it to your disk. You can view information about these minidumps to help identify the cause of the blue screen.
Blue screens also look a bit different, depending on what version of Windows you’re running. In Windows 7 and previous versions, the blue screen looked much like a terminal screen, displaying all manner of information. In Windows 8 and 10, blue screens are much simpler. That’s really not as big a deal as it sounds, though. Even in previous versions, blue screens tended to go by fast enough that reading that information was difficult, anyway. And there are easier ways to get all the details you need for troubleshooting.
What is causing the iusb3xhc.sys BSOD crashes?
We investigated this particular issue by looking at various user reports and the repair strategies that are commonly being used to fix this particular error message. As it turns out, there are multiple causes that could lead to a BSOD of this kind. Here’s a shortlist of potential culprits that can cause constant iusb3xhc.sys blue screens:
Corrupted / Incompatible USB Host Controller drivers – As it turns out, this particular issue can also occur due to a corrupted or incompatible Host USB Controller driver. If this scenario is applicable, you should be able to resolve the issue by uninstalling the Host USB controller drivers via Device Manager and reinstalling them at the next system startup.
Intel Chipset drivers are not installed – Missing Intel Chipsets can also be a potential cause for this issue – especially if you’re using a motherboard that is designed to work with these drivers. In this case, you should be able to resolve the issue by using the Intel Support Assistant utility to install the missing firmware.
System file corruption – System file corruption is another possible cause that might lead to unexpected BSOD crashes related to the iusb3xhc.sys file. If this scenario is applicable to your particular case, you can resolve the issue by fixing the corrupted system file with a utility like DISM or SFC.
Overprotective security suite – Judging from various user reports, this particular issue can also be caused by an AV or firewall that is interfering with the host controller driver. In most cases, Karsperksly is singled out as a culprit capable of quarantining a dependency of the Host controller driver. In this case, you can resolve the issue by uninstalling the 3rd party security suite and removing any remnant files.
Cached memory issue – Another possibility is that you’re dealing with badly cached data regarding the usage of your memory. If this scenario is applicable, you will be able to resolve the issue simply by opening the case of your unit and taking out the CMOS battery.
