Okay I have noticed I have an error with SOJU SCSI Controller, in the deive manager it has an exclamation mark on the icon, and it gives me this messege in the device status

The drivers for this device are not installed. Code 28

To reinstall the drivers for this device, click Reinstall Driver.
So I reinstall the devices, then it says

An error occured during the installation of this device

the driver installation file for this device is missing a necessary entry. This may be because the IFN was written for Windows 95 or later. Contact your hardware vendor
I have reinstalled the driver etc; scanned for hardware changes but it still comes up with this error, im running Windows XP SP2, on an AMD Sempron 2800 and this is the first time this error has happened.

Any ideas?
