Asmedia Usb Host Controller Driver Please Uninstall

ASRock Z77 Extreme 4 Motherboard, Windows 8.1 Pro, Antec 900 case.
My USB 3.0 ports don't work. If I try to uninstall some of the drivers/devices in Device Manager, the computer freezes. If I try to install the Asmedia_USB3_Win8-64_Win8(v1.16.2.0) Driver, the computer freezes. If I try to install the Broadcom_Lan(v16.2.4.1_64Bit) driver (update from 15.6.1.2) the computer freezes. When I tried to install or uninstall the driver for my Creative Sound Blaster X-fi go! pro USB sound card the computer froze. I opened the Task Manager and closed a bunch of programs and eventually got the Creative driver to install. Tried the same with the others and it still caused the computer to freeze.
Not sure what the cause of this was, but on 2/27/2014 I had an assignment for my A+ Hardware class to attempt to update my drivers, and the only driver that was out of date and updated was the ASMedia USB 3.0 eXtensible Host Controller driver.
The computer worked fine until several days ago when, all of a sudden, my USB 3.0 ports quit functioning. I have 2x USB 2.0 ports with my Creative USB sound card in one and the dongle for my Microsoft mouse and keyboard in the other. I have a Logitech F710 gamepad in one of the back USB 3.0 ports (I believe these run on the ASMedia driver) and occasionally I use a couple of flash drives in the front USB 3.0 ports (I think these run on the Intel 3.0 drivers.)
Anyhow, when they quit working several days ago I eventually just restored my computer to a few days earlier using System Restore and everything worked fine after that. Then today I was watching a movie on the computer - I went to restart the computer afterwards and was getting ready to play some games. After the restart, my USB 3.0 ports quit working again.
In the Device Manager, under Other Devices, there were two items with the yellow exclamation marks that were labelled as USB Root Hub (xhci). After uninstalling them and some other USB stuff in the Device Manager, they eventually said Unknown device, which is the label they currently have.
Under Universal Serial Bus Controllers I have ASMedia USB 3.0 eXtensible Host Controller - 0096 (Microsoft) and Intel(R) USB 3.0 eXtensible Host Controller - 0100(Microsoft)
Earlier today I managed to install the Asmedia_USB3_Win8-64_Win8(v1.16.2.0) successfully and things started working fine. At some point, before or after this, I really can't remember I also followed a guide to change the Intel_USB3_Win7-64_Win7(v1.0.4.220) so that it would work on Win 8.1 and it seemed to install just fine. After getting the 3.0 ports to work again, then front ones quit working yet again for no apparent reason, while the back ones still continued to work. Then, while messing around in the Device Manager, I accidentally updated the ASMedia USB 3.0 eXtensible Host Controller - 0096 (Microsoft) again and all 3.0 USB ports quit functioning again.
I read that Microsoft provieds the Intel 3.0 USB driver and that Intel stopped making them after Win 7. The ASMedia 3.0 USB driver provided by ASRock is listed under Win8 64, but not 8.1.
My mouse is USB so I cannot uninstall many of the USB drivers under Device Manager without stopping my mouse and keyboard from functioning. Trying to uninstall certain devices there causes the computer to freeze. Trying to install the Asmedia_USB3_Win8-64_Win8(v1.16.2.0) causes the computer to freeze. Trying to update my Broadcom NetLink Gigabit Ethernet adapter driver causes the computer to freeze.
I've spent all day searching and reading and can't figure this out to save my life. I really don't want to reformat, either.
Incredibly long and convoluted but that's what I have. Any ideas; anyone? ...
Asmedia Usb Host Controller Driver Please Uninstall

On a clean installation of Win 10 1703 I'm having an issue with the installation of the ASmedia USB drivers provided by Asus for my Z97-A mobo. The exact error message during installation is the Asmedia USB Host Controller was not found.
I can't see any evidence manual or otherwise that the Z97-A actually has Asmedia USB controllers but because the driver is offered I assume it does...
Microsoft appears to have installed 'their' USB drivers as seen in Device Manager but I cannot verify whether these drivers are allowing full USB functionality, i.e. USB 3.0 etc. AIDA64 reports the controllers as
USB2 Controller Intel Wildcat Point PCH - USB 2.0 EHCI Host Controller 1 and
USB3 Controller Intel Wildcat Point PCH - USB 3.0 xHCI Host Controller
I have the program usbtreeview and if I'm reading things correctly (not certain) all of the USB ports on my board are only doing USB 1.0 speeds.
I don't recall having any issues with mobo supplied USB drivers prior to Win 1703. Has anyone got any ideas? I'm not certain as to what USB drivers Microsoft has installed but there is a reference to Asus in one of the driver details boxes in Device Manager for USB Root Hub (USB 3.0) USBHUB3.SYS and ASUSFILTER.SYS.
