Computer won't post Tags: New Build Computer Motherboards Systems Last response: August 17, 2010 9:40 AM in Systems Share offthehookah August 16, 2010 7:27:43 PM I had this build and it was running fine but I decided to upgrade the motherboard... 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?

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. m 0 l Related resources Computer won't post/Boot after installation of new Mobo and power Supply. - Forum computer wont post/boot after removing motherboard - Forum Computer won't enter Post - Forum New computer wont boot, wont post, no fans and only the standby light. - Forum computer wont post - Forum Can't find your answer ?

Make sure all your USB connectors are correctly placed and no USB ports are damaged. Make sure the board is not in direct contact with the case. m 0 l Can't find your answer ? Ask !
