I just bought a new Samsung Spinpoint F3 to use as a system drive in my computer. I cloned the old disk to the new drive and when I boot up everything is slow. My OS is W7 HP x64 and my motherboard supports SATA 3Gbs. My BIOS settings should be fine but I just don't have any idea what is causing the problem. I partitioned with Parted Magic, changed the SATA cable but boot up and everything else is just way too slow. What can I do? Thanks!
