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 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.

- Press the Win+X keyboard hotkeys and click on Device Manager.
- From Device Manager find the ASMedia XHCI controller entry.

2. Roll back drivers
- Bring up Device Manager once more, as already explained above.

If you cannot update the existing drivers (there isn’t any update available) but you know that everything used to work without problems before you applied the system update patch, a rollback must be performed.
