I recently changed out my A75 s211 motherboard with an A75 s206 motherboard. When I reassembled it and turned on the power. The power light came on and the fan came on for a short time and went off, but nothing appeared on the monitor. The lights for the key board wont come on either. I thought it may be that the 206 motherboard will not support the parts from the 211 but the same thing happened when I duplicated the assembly back to the S211. Can anyone provide me with some direction on this.
