System errors are one of the worst problems that PC users may experience. They are often followed by the infamous BSOD (the blue window error) with very little information on what triggered the issues in the first place.

So, you need to find the right fix, based on an error message or code. The same is valid for the asmtxhci.sys BSOD, a common problem which can be addressed with the help of the following troubleshooting solutions.

The BSOD that says SYSTEM_SERVICE_EXCEPTION (asmtxhci.sys) is caused by the drivers which are associated with the ASMedia controller. These are drivers for USB 3.x ports, usually used on Asus computers or on any other devices using Asus motherboards.

So, we are discussing about a driver problem that can happen after a system update or after you install a certain app or program on your computer. Anyway, here is how you can fix this annoying BSOD.
