So, apparently my ThinkPad T42 mainboard has water damage. (I sent it in for a simple power regulation issue... and it was shipped back to me saying it was water damaged, except after the half-wits in Memphis got done with it, it wouldn't boot at all and gave a video-related beep code. Thanks guys.)...

I'm having the same isue now with my T42... which is unfortunately out of its three year warranty period. (yes, I know the T42 hasn't been for sale for three years. It's a unique situation to say the least.)

Is there anything I can do short of replacing the system board?
