Okay I am stumped. I have a brand new MSI KT 266 Pro 2 Mother board with an AMD 1.8 Ghz chip. 512 Mb ddr ram. I have connected everything, and checked all connections. Problem??? Nothing works. Power supply will come on, and the fan for the chip operates, power button to turn it on and off works. However, hard drive, cd/rom, monitor, and floppy drive do not operate. As if there is no power. Any suggestions??
