I have tried all day to load windows 7 on GA-MA770T-UD3P Motherboard with a 630 propus chip, seagate 750GB SATA HDD, and Mushkin BLackline DDR3 1333-10666 memory. I have done so with the help of my neighbor who spends all day testing components for companies like intel and amd. He seems to think that the problem is with memory compatibility. This memory was not on the list of acceptable modules on the GIG site. Is there any reason to believe that this is not the reason for the failure that i am having. I have tried updating bios as well as drivers for sata. Windows will start and then say that it is unable to complete installation until after reboot then does the same thing. I am fried and have no idea what to do. I have windows 7 ultimate and a brand new rig and i can't even get the damn thing to work. I am a newb but i don't think that explains what is happening. Is their any reason this setup would do great with WIN 7 with the exception of the RAM because of incompatability. ANSWERS PLEASE!!!! I have already requested RMA for memory, do i need to add to the list.
