|I have good news and bad.|
Good news is you know it didn't work in Vista. Bad is that since that is so I doubt W7 will fix it.
Look also at event viewer logs.
Look at how the pcmcia is installed. Look for a pci to pci bridge in system properties.
Lastly did it ever work in xp? Did you install any xp drivers or did you just let it install?
Other sites have suggested you check ram, use memtest or other.
"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10
