I just built a new machine a MSI 770-C45 AM3 AMD 770 ATX AMD Motherboard, AMD Phenom II X2 550 Black Edition Callisto 3.1GHz Socket AM3 80W Dual-Core Processor and G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Dual Channel Kit. I have been trying to get this to work and I am having no luck. I have installed several different OS and have had the same issue. I cannot install any programs ie. Alcohol 120, Nero or office. I had these programs on several different machines without a problem. I am currently running Vista but have had XP and Windows 7 installed each with the same issue. My firste HD is a WD 80GB without any jumper and the second is a WD 320GB and again no jumper. Anyone have any knowledge of this issue?? Please help
