Explorer and other Apps hang randomly

Hey everyone,
Im new here but I was hoping I would be able to get a little help
and/or see if anyone has experienced this before. With my computer when
I go to access anything through explorer or directly from another
application, it will hang for a moment before actually doing what I told
it to (browse folder, open music through itunes....). This is a new
problem to me since I switched over to 64bit, but I also began using the
Promise TX4 Sata300 at the reformat for my storage drives.

My assumption either that the controller is allowing the drives to spin
down and it has to spin them up before allowing me to access them (but I
never had this problem when they were directly connected to the MOBO) or
that the controller has some problem with access times (since I dont
know much about sata controllers). It is a noticeable hang (4-5secs) and
really picks at me. I have already tried reinstalling the controller
drivers.

System Specs:
Windows Vista x64 Enterprise Edition
Intel e6600 @ 2.4gHz (stock)
6gb Patriot Memory
EVGA Nforce 680i A1 MOBO
Promise SATA300 TX4
WDC Raptor 150gb (OS)
WDC Raptor 36gb (working drive)
WDC Caviar 250gb (on promise controller)
WDC Caviar 500gb (on promise controller)
WDC Caviar 500gb (on promise controller)
WDC Green Power 1Tb (on promise controller)
