ASUS m4a79xtd Evo Mobo 3.2 Ghz Phenom II quad core 4gb DDR3 320gb HDD 4850 Radeon Ati I changed the motherboard to the MSi 790FX-GD70 http://www.newegg.com/Product/Product.aspx?Item=N82E168... and ever since then my computer won't start up (it starts but the processor fan doesn't spin full speed) Any theories or things to check for? More about : computer post offthehookah August 16, 2010 9:37:39 PM the ram is xms3 DDR3 ram zach538467 August 16, 2010 9:47:31 PM Most likely DOA. Do you have a speaker hooked up to it? They are cheap and if it is throwing any codes you could troubleshoot from there. If it is not even posting though, most likely time for an RMA.
