I totally agree with Mounty, because I almost have an indentical setup as him:

-Windows XP SP3 (clean install)
-2 SATA HDD RAID 0 with NVRaid driver (NF4 Intel mobo)

I have random system freezes when I use an image located in the RAID, and I didn't have any problems with the previous version, which I've downloaded from another website (not available in your website anymore).
