vista freezes randomly

[vistauser]

hello,

i have quite the annoying problem with vista.

i recently installed a WD320GB SATA2 7200 HDD on my computer.

This HDD is an addtioion to a current SEAGATE HDD 220GB SATA2.

The issue is that for some unknown reason vista freezes without a warning,

whenever i close a window,close explorer,add a Link to WORD,open my documents etc..

And i need to hard reset the comp to get it to work again.

It didnt happen before.

i have an MSI MotherBoard,and the two HDD are connected to Controller2,

could the problem be that both HDD are connected to the same controller?.

The controller is NVIDIA nForce Serial ATA Controller when the HDD are:

PORT1-WD320GB

PORT0-SEAGATE HDD

the comp is:
