[QUOTE="cwa107, post: 890449, member: 24098"] Not sure if you can see the actual system board (it might be covered up to keep things aesthetically pleasing), but if you can get to it, take a look at the capacitors on the board: [IMG]http://home.comcast.net/~cwa107/forumimages/caps.jpg[/IMG] The picture above shows capacitors that are going bad (notice how the tops are not flat), this is very typical of machines of this vintage - they will either poke up or electrolytic compound will come out of the tops. In 2003-2004 a rash of bad capacitors were produced by a Taiwanese conglomerate and were widely distributed to systemboard manufacturers, including companies that supply Apple, Dell, HP and many others. After some time, they go bad and start to vary their storage traits, causing all kinds of odd behavior. This is the first thing I look for when I hear this kind of complaint. If this is the case, you can either replace the capacitors (not easy unless you're handy with a soldering iron) or replace the entire board. [/QUOTE]
