Just built a system today and I can't get my new system to post. It's\na MSI K8T Neo, A64 3000+ retail, Evga 6800 GT, 1GB Crucial memory, WD\nRaptor hard drive. The motherboard came with a diagnostic attachment\nto plug into the USB on the motherboard and it has 4 LED's on it to\ntroubleshoot problems. Well, it has four lights lit up which\nsupposedly means faulty or misinstalled CPU. Well, it's not\nmisinstalled as I've reinstalled it a couple times and it fits\nperfectly and has good contact with the heatsink/thermal pad. I've\nalso tried different memory (albeit Crucial as well, but old pc2100\nstuff) that I know works. So, is it really the CPU? How accurate are\nthose diagnostic LED's? Did I get a bad CPU or is there something\nelse that I'm not trying? Thanks in advance everyone!!
