Well when you say your startup is slow as hell, was it slow as hell before you put the NEC in your 'puter?? Or did it become slow as hell after you put the drive in. My only reason for asking is because if it was slow before inserting the drive, and you have the type of machine you have...I'd venture to say y ou need to do some spring cleaning on your rig.
I never really mess around with spring cleaning though becuase I just tend to re-install everything. BTW, re-installing everything is easy if you consider restoring a ghost image "re-installing"
