Weird problem with Mobo, need some help!!

[shalldoom]

Ok so i made this build 2 month ago: Phenom II 940 BE
GA-MA790GP-UD4H (Gigabyte)
2x 1G 1066 Kingstone Hyper X
XFX Geforce 8800 GT 512
320GB caviar WD HD
my old PSU 300W
3Daurora case
my old 19 Viewsonic lcd

The problem: Went yesterday and bought a new 500W OCZ Stealth stream PSU and a 640 GB Caviar Blue HD, after installing the new PSU and HD, every time i try to copy any thing the pc hangs and i have to reboot. The strange thing is that i can access any thing on the 320GB HD with out a problem ex: watching a movie , playing a game, listening to music ect. but, if i try to access anything on the 640 GB drive its extremely slow....whats even more strange is that when i swap the new PSU with the old one, the thing works just fine again.

Failed Attempts to fix:
1- Bought 2 new PSU's 450w and a 600w, both can't copy without hanging.
2- Changed the sata cords and changed positions on the Board
3- Disabled/Enabled cool & quite, fail-safe, optimized defaults in bios
4- Bought a 2000W Voltage Stabilizer.
5-Bought a new 500GB Caviar black HD, same thing slow and hangs when i try to copy.
6- Changed RAM positions.

Any help would be greatly appreciated.

Which OS? I'm wondering since you've apparently cloned the drives??...If you've created a problem with multiple copies of a Windows OS. It could also possibly be that both drives have an active boot partition. My real suspicion, though, is that you've two drives with C: competing for dominance. Without disabling the active partition on the cloned drive, Windows cannot assign a unique drive letter to the cloned C: drive...

This sounds like a Paul Komski question... ;)
