tried pushing down on that U975 chip while booting but that didn't do anything. any suggestions on what cleaner to use that won't ruin circut boards? i have this stuff from radio shack that's god awful. everything you try to clean with it it just gunks up and they call it, electronic cleaner. but i don't think it's actually safe on any electronics I know of.
The only thing I use on Circuit boards, is pretty much the ONLY thing to use, is Isopropyl Alcohol. That stuff that evaporates in seconds..
And no, you cannot drink it....
