and my computer won't even start. I followed all the directions that were included with the motherboard and supplemented them with a how-to that i found online. I have double- and triple-checked all my connections and everything seems to be sound. components are: -Asus m2n-e sli socket am2 nvidia nforce 500 sli mcp atx amd motherboard -AMD Athlon 64 X2 5200+ Windsor 2.6GHz 2 x 1MB L2 Cache Socket AM2 Processor -Kingston HyperX 1GB 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Desktop Memory -BFG Tech BFGR79256GSOCE GeForce 7900GS 256MB 256-bit GDDR3 PCI Express x16 Video Card -HIPER HPU-4B580-MS ATX12V v2.2 580W Power Supply 100 - 120V what could i be doing/have done wrong? this is my first time installing a new cpu/mobo, but everything went according to the directions so i wasn't expecting this to happen, can anyone help? edit: ah, forgot to say that the SB PWR led comes on when i have the computer plugged in and the psu switched on and when i initially hit the power button both the cpu fan and rear fan start to spin for a split second and then stop.
