SCSI controller - 'code 10'

Hi,
Hope someone can help?
Have a problem - my system started in safemode so I restarted it but the
display had altered (ghost-like and colours altered but settings unchanged).
Looked in Device manager and have the yellow exclamation mark under "SCSI
Controllers" for "DMX3181X ISA SCSI Host Adapter" (other listed is for
EPPSCSI miniport driver - all ok). Under resources tab says code 10 - device
drivers either not present or not working properly.
Have searched everywhere to reinstall but can't find the original driver in
my system.
Anyway, is this affecting the display or is this 'host adapter' only related
to my scanner? I'm confused!
I need to get my display happening again and can't. Where can I get new
drivers for that and what info do you need to help? Many thanks for any
assistance.
