Acer Extensa 5630 Black Screen

My son's Extensa 5630 laptop is not booting up and giving a black screen. It did this and I was able to get into the system repair and restored it to an earlier date. It worked for a couple days then died again. I think it is the hard drive, so I bought a Western Digital WDBABB2500ANC-NRSN 250 GB SATA, I set it to boot to the CD ad tried loading windows. It started to go, seemed like it was writing to the hard drive then it blue screened. The old Hitatchi drive is 3gb/s and this one is 1500mb/s. Is this my problem, the Motherboard will not support this hard drive?? Is there a way I can make this hard drive work? Help!
