Well if your board is dead you'll have to find out what the OPN number is on your CPU. (IE: AXMG2600FQQ4C is a mobile XP2600+.) Write down everything, post all the codes here and someone can help.
Since Socket A is a little long in the tooth you might consider looking at a new CPU and motherboard - Socket 939 or at least 754 (which is very cheap today).
