I want to add an extra drive to my 760 which only has two sata ports. I am using these for main hard drive and DVD rewriter. I need to add an extra peripheral card to drive the new hard drive. I have tried a couple of pci cards with no success.

I have an Inspiron 7520 that originally came without a msata card. I've changed the daugtherboard and installed a 128Gb Crucial mSata Card. My idea is to use the msata as an individual Unit with SO and common applications and the Original 750gb HDD for the rest of the data (Not an Hybrid disk).

Last time I fixed the problem by rolling back an NVIDIA driver. However, I am still using the rolled back NVIDIA driver (the good one) and the problem has reoccurred. I tried recovering Windows 7 to a restore point, but the oldest restore point I had, dated March 28th, did not fix the problem.
