I once bought a 3400 logic board and it did not work. It would 'bong' but then stop. After VERY close examination of the board (magnifying glass) I found no less than 17 cracked solder joints of the RAM chips' pins on the board. I am refering to the 16MB of RAM which is soldered to the board, not any extra RAM modules. Anyway, I resoldered the joints and it worked perfectly. Definately worth a little time spent with a magnifying glass. Greg __________________________________ Do you Yahoo!? SBC Yahoo!
