hi, I brought a xps1530 with vista32bit 3-4 months ago and it run fine. to make some test on 64bit platforms I have to install my educational license of vista64bit business; I've download all the drivers from the dell site and all seem to work good except for the hard drive, sometimes (from 1-2 times a minute to 10-20 minutes) it makes some clic-clac (like it shutdown and after 1 seconds startup again) how do I solve this issue ?? (i found the same issue on Linux and there I fix it by setting some advanced acpi parameter of the hard drive)

thank you in advice.

Davide

p.s.: if it's matter i brought it in europe and i'm sorry for my bad English
