    I have an ASRock G41C-VS motherboard which as the specs tell me
    Supports FSB1333/1066/800/533 MHz CPUs
    Supports Dual Channel DDR3 1333(OC) + DDR2 800
    I replaced the 2x2 DDR2's with a Corsair 8GB DDR3 1600MHz Vengeance PRO DIMM 9-9-9-24 2x240-pin Red Heatspreader as the specs said the max for this motherboard was 8Gb but although the all the corrects lights come up the computer will not boot up?

    Seems like you have the wrong RAM. Did you put the old RAM back in and see if it will boot?

    This site http://www.crucial.com/usa/en/systemscanner will tell you exactly what you have and what you can put in. It is a small download and doesn't stay on your PC. It is a safe site as I have used it as many other have hundreds of times.

    A little more reading for you. http://www.makeuseof.com/tag/difference-ddr2-ddr3-ram-technology-explained/

    However, purchasing DDR2 or DDR3 RAM isn’t usually a matter of preference. DDR2 and DDR3 RAM are not compatible. If your motherboard uses DDR2, you cannot upgrade to DDR3 without upgrading your motherboard. This means that if you currently own a computer with DDR2 RAM and you want to upgrade to a brand new processor and motherboard you have to throw your perfectly good DDR2 RAM and buy new DDR3 RAM.

    There are a few motherboards which are exceptions to this rule, but they are exceptions only because they provide both DDR2 and DDR3 RAM slots, and these exceptions are available only on older chipsets.

    John. Did you try the Crucial Link to see what it says?

    Hi John.

    Here are the memory specifications for your motherboard:

    I think this is the problem:

    You are using DDD3 memory at a frequency of 1600 MHz which your motherboard does not support. You can install up to 1333 MHz DDR3 memory and NOT 1600 MHz.

    On a computer a Windows 32-OS is only going to recognize 4GB of RAM. I read your MB specs There are two red stars in the memory specs that states there: Due to the operating system limitation, the actual memory size may be less than 4GB for the reservation for system usage under Windows® 32-bit OS. For Windows® 64-bit OS with 64-bit CPU, there is no such limitation

    ij50 it also follows up with this ...**In order to maximize the system memory, please install two dual sided 4GB memory modules.

    Sorry Evan I started to post but wanted to reread crucial specs and MB specs. So I did not post any misinformation.

    Well the information is incorrect on Crucial's website then.

    Just go by the information from your motherboards specifications which indicates in this case that you can install up to 1333 MHz DDR3 memory and nothing higher than that.

    Also as LJ pointed out you won't be able to use more than 4 GB's of RAM on a 32-bit OS.

    So do you still need assistance with upgrading the memory or are you going to keep the original two DDR2 sticks in?

    Evan I cannot see any point in trying to upgrade to 8Gb when the OS will only run 4Gb

    You can upgrade to 8 GB's of RAM but you will need to perform a clean install of Windows 7 64-bit in order to use all 8 GB's of RAM.

    You would need to buy 2 X 4 GB sticks of DDR3 1333 MHz memory and then after the memory is installed you would need to format the hard drive and install Windows 7.

    Are you interested in doing this process or are you satisfied with your current setup?

    Well yes Evan I am interested but it is the cost factor it would cost me about $150 for the Windows 7 64 bit to start with !

    Actually no it won't. As long as you know what your Windows 7 product key is then the product key will work with the 64-bit version of Windows 7 and you won't need to buy a new copy of Windows 7.

    Did Windows 7 come preinstalled on the computer or do you have a Windows 7 64-bit DVD available?
