Also if I'm reading things correctly it has to do with the +5 volt rail, but it seems strange that all these issues would be caused by a single sad cap that's kind of out of the way. So I'll keep looking for what is causing these problems in the meantime before I find a replacement and see if that changes anything at all. |
