The "usb enhanced host controller" was deleted from the Device Manager in Windows XP.

Now, the computer will boot up normally, but I can't use my keyboard or mouse once Windows opens. I use a USB keyboard and mouse because my old PS/2 slot quit working.

I can enter BIOS by hitting the F8 before Windows opens, but beyond that I don't know what to do.

I have a copy of the Windows XP disk that was given to me from the shop that sold me the computer. It is not "genuine".

I suspect there is a simple way to undo what I've done, but I don't know what it is.

Any help is appreciated?

THANKS,

JNull1. Computer Specs. If a brand name computer, please supply "Make" and "Model Number", otherwise the make and model number of the motherboard (if possible). Also desktop or mobile (notebook, laptop)?

2. Operating System. Windows XP what? Home Edition, PROFESSIONAL? Original, Service Pack 1 (SP1), SP2, SP3?

3. Can you use the keyboard while in CMOS setup (to configure the BIOS)?

4. How many PS/2 ports are on the computer case?Hi. I'm travelling, so I can only give you some of the details. I'll tell you what I can for now.

It is a generic desktop computer with Windows XP Professional, SP2 and I do run automatic updates.

I do not know the make or model of the motherboard.

I was able to use the keyboard in BIOS.

There are 2 SP/2 ports on the back, but neither seem to work. (I've tried with 2 different SP/2 keyboards.) I have been using a PS/2 to USB adaptor to run my keyboard for the last year or so.

Thank you.Even if that controller was accidentally deleted it is automatically reinstalled on a re-boot of Windows...
However some generic Windows drivers don't fit the bill always so re-install your MBoard drivers and re-boot...Will do.

Is there any risk of losing data on the computer when I reload MBoard drivers?

(BETTER safe than sorry, which is why I'm asking.)

Thanks.Shouldn't be...but it's a good reason to examine what backup strategy you currently have in place.
