Tags: Motherboards Last response: February 2, 2011 10:59 PM in Motherboards Share smoothcannibal February 2, 2011 10:06:59 PM this is the first time i have ever just replaced the motherboard. i have built three systems from scratch. long story short is i can't get it to post. all the fans spin but thats it. specs: biostar g31m+ motherboard Intel Pentium D 820 Smithfield 2.8GHz LGA 775 95W Dual-Core Processor stock heatsink G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 533 (PC2 4200) Dual Channel Kit System Memory onboard graphics ATRIX PSCI-500BLK 500W ATX12V Power Supply 1 120mm coolermaster fan, two 80mm coolmaster fans skythe 5.25 inch bay fan controller with lcd. hp dvd writer ide seagate barracuda hard drive COOLER MASTER Centurion 541 RC-541-SKN1 Black Aluminum bezel, SECC chassis MicroATX Mini Tower Computer Case i've tried my best to troubleshoot this. taking out parts in any combo i can think of. the only time it beeps at me is when the cpu is installed and there is no ram. i though i had a bad board and i exchanged it for the same board. no change. i have tried two psu, two brands of ram, a different case. the only thing i haven't tried is a different cpu. i know it works. i'm using it right now. i have all the parts listed minus the mobo working and running windows stable. which is why i am able to post this.

If the CPU isn't supported, there is a high likely-hood the PC will not run unfortunately. smoothcannibal February 2, 2011 10:59:10 PM ah man!!!! i didn't even see that. i told the guy which processor i had and that is the board he sold me. i sent a inquiry to biostar about the latest bios they have on the site and if that may support it or not.
