That is your NEC Electronics USB 3.0 Host Controller Driver which is owned by Renesas now. Renesas requires registration and a whole lot of research to find drivers, so I would suggest you try to find drivers from your Manufacturer.

This is generic Hardware error and does not say which piece of hardware it is. It will almost always blame the CPU, because it is the CPU that detects the Hardware error and throws the code to shut down the computer to avoid any damage, but it is not usually the CPU that is the error.
Please fill out your System Specs
Information
Your System Specs will help us to help you, and doing it in this manner will make them available to all helpers in every post and keep us from hunting for them. We ask that you fill them out in as much detail as possible including Desktop or Laptop, Model number if it is an OEM computer and all components with the Manufacturer and Model number if possible.
If you will go to your last post and click the 'System Specs' in the bottom left of the post, you will find a link to update your system specs. Please fill those out in as much detail as possible, making sure to click save at the bottom of the page. If you would like to know what we would like, you can click 'My System Specs' at the bottom left of this post to see mine. If you do not know what your components are, this will help you accomplish this task.
System Info - See Your System Specs
Open a elevated command prompt ( click start, type cmd in the search box, right click on the cmd entry and select run as administrator) in the black box that opens, copy/paste sfc /scannow. If you decide to type it, notice the space between the sfc and the /. It is a system file checker which will scan your system files and attempt to correct any missing or corrupt files. What we want are the results to say windows found no integrity violations. If it says files were found but could not be repaired, close the box, reboot and run it again, after opening the administrative command prompt. You may have to reboot and run it three times for it to repair all system files. If it can't repair them after 3 reboots, let us know.
Also, please give me any info you can on what activities cause it or what programs you are using that cause it. Anything you can provide will be a help.
