Scenario: Core 2 Duo processor, Gigabyte MB, 4 SATA Western digital 500 GB hard drives, windows 7 64 bit.

Problem: Copying data from USB or among SATA hard drives is faulty. When trying to copy 20GB from one HD to another it starts off with normal ~14-15 MB/s transfer rates and eventually bogs down to < 120KB/s transfer rates. If I leave it alone over night I come back with my computer crashed and setting at BIOS detecting hard drives.

Troubleshooting: Removed all but 1 HD with OS on it, everything seems to be happy. I can copy large files from USB HD to main/single HD. Ran SpinRite on all hard drives, no errors found. Tried adding one HD to machine and problem exists, tried switching SATA cables, and SATA ports on MB. Reinstalled windows 7 x2 (from different disks..).

Oddly enough if I boot to a ubuntu everything works fine.

Getting ready to purchase a new MB, but wanted to see if anyone had suggestions. Thanks!
