|"2x300gb velociraptors in raid0"|
Nothing to do with your problem but what do you accomplish with a raid0 setup? You do realize that if you have a harddrive crash in a raid0 configuration you lose ALL your data.
I fail to understand why anyone with a large drive, over say 120gb would not partition it to have windows on it's own in say 60gb with the rest as either a single extended partition or multiple partitions for progs, data, music, movies etc
Why would anyone want a single 600gb partition? Defragging such a monster would take hours.
As for your actual problem, It is unlikely the beeps relate to the LAN port. They are more likely to relate to ram or graphics and to find out what they mean, determine what version of bios you have and then visit http://www.bioscentral.com/
