How to remove a System Driver in XP???

By head ·
I installed a Sunix Multi-I/O card and the distributed drivers. There were problems, and I eventually removed the software (in Add/Remove Programs), and the card itself. My system boots and runs, but Msinfo shows the three Sunix drivers as still being present (Stopped, Manual). The device does not show up in Device Manager, even displaying Hidden Devices. Is there a way of removing them entirely??

The reason I ask is that if I plug the Sunix card back in and boot the system, it hangs about 60 seconds after the desktop is displayed, maybe when Found New Hardware as about to run. I suspect that the (faulty) drivers are being activated.

Have you checked yet in MSConfig ? ...

There may still be an entry in the boot.ini sequence.

Start > Run > type msconfig then Enter.

Check in 'Services' or 'Startup'. If you find any entries for these items, uncheck them, click Apply then OK.

You will have to restart anyway so it'll confirm if you've been successful.

Alternatively get hold of a download of Autoruns and use it instead.

Detective Work

by TheChas In reply to How to remove a System Dr ...

It takes a lot of diligent detective work to remove pesky driver files and references.

The first issue is that many uninstallers do not remove all of the files they should. Odds are there are a few DLL files and or VXD files in the Windows/System32 folders for this card.

The next issue is that the registry remembers EVERY bit of hardware that has ever been installed in the system.

Therefore, unless you are comfortable editing the registry, you may not be able to rid yourself of the driver remnants.

WARNING: editing the registry can disable your computer. Always make a backup copy of the registry prior to making changes.

Look in both the Hardware and System keys. When you find references to the Sunix device and it's files note down the information prior to deleting the key.

Key names and words can help you search the rest of the registry for additional keys you need to delete.

File names can help you locate left over system files.

Use caution when deleting any registry key.

Once you have some file names, you can search for them in the system folders. While not 100% accurate, it is typical for most of the driver files for a specific device to have the same date and time stamp.

Some of the registry cleaners and uninstallers do a decent job of cleaning things out to.

Thanks Guys

by head In reply to How to remove a System Dr ...

Autoruns did the business for me. I was then able to re-install the card and boot the system ok. Then went through the driver install carefully, and ran into problems after it had installed the two serial ports ok, and was about to start on the parallel port, when it hung.

I'm not sure that it's worth persevering with this card, but at least I learned something new today, so It's not a dead loss!

Thanks again.
