It probably goes beyond the driver as it sounds as though the aborted
installation has corrupted your boot configuration and appears to be
corrupting it each time you manage to get to the desktop.
Try using your method of getting to the desktop and then try using System
Restore to take you back to a time prior to when you did this installation.
This is only meant to restore your settings and registry but you should be
sure your data is well backed up. Start Menu\Programs\Accessories\System
Tools\System Restore.
If that fails to resolve it or you don't have an early enough restore point,
try booting from the Vista CD, at the setup screen, use the repair option.
This is designed to repair the startup configuration. Again, since you have
a method of getting to the desktop, be sure to use it to make sure your data
is well backed up.
If that fails to resolve it, it would appear you are looking at reinstalling
Vista and I strongly recommend you do a clean install, not install it over
itself.
Yes, actually, Vista is pretty good about preventing Non-Vista drivers from
installing as the hardware newsgroups and even this newsgroup can attest
based on the number of legacy hardware devices that refuse to install.
However, some users are pretty ingenious at getting things to install, well,
the drivers anyway only to find afterward, the system balks. You didn't say
if this was Vista compatible. Nonetheless, as you have found, good as it is
at this function, it's not perfect and a user should always be wary of
installing any software about which they have questions as to full
compatibility.
