Hello,
As I checked the specs of your PC, it seems to have SATA-II which the SSD is compatible with. I would require more info to find out the cause.
Do you see the SSD in bios?
How many drives are connected to the motherboard at one time?
Did you check the boot sequence to see if the SSD is the primary boot drive?
How did you install Win 7 on the SSD?
Thanks!!!
