    New hardware not working


    I bought some new hardware for my computer, 2x4gb ddr2 ram, a zotac nvidia gt 730, and an amd phenom 2 b59. No response from my computer at all after turning it on. No lights from keyboard or mouse and nothing on monitor. I have a sense that this issue is linked to my processor, as I bought an am3 processor and my motherboard has an am2+ Socket, but I was under the impression that am3 are backwards compatible with am2+?? Let me know what you all think.

    Did you really mean DDR2 thats old stock, possibly incompatible with motherboard.

    An AM3 CPU will not work in an AM2 socket. You may have caused electrical damage to your CPU.

    However, an AM3 chip will work in an AM2+ socket, apparently...

    From Wikipedia:
    AMD confirmed that there is an upgrade path from Socket AM2+ to AM3:

    • AM3 processors work on AM2+ motherboards due to the presence of both the DDR2 and DDR3 memory controllers on the processor
    • AM2+ processors do not work on AM3 motherboards due to the processor's lack of a DDR3 memory controller

    The pin configuration of the AM2+ socket (940 pins)[2] is mechanically different from the AM3 socket (941 pins)[2]
    Even though Wikipedia isn't the greatest source for reliability, it seems to have a point here. I highly doubt that this is a good idea, though. The best practice is to use the correct socket for the processor. In your case, I would buy an AM3 or AM3+ motherboard before you damage that CPU.
