Andy Cuffe -- Use this email address first The first thing to check is that the capacitor replacement was done properly -- polarities were honored, no solder bridges were created where they didn't belong, the board wasn't shorted when it was put back in the case, etc. Then debug as if it were a new motherboard. Start with nothing more than is necessary installed (e.g. just a video card and some memory). Since it was out of the case, something else may have been disturbed. -- The e-mail address in our reply-to line is reversed in an attempt to minimize spam. Our true address is of the form . |

Andy Cuffe There's still hope, check the voltage regulator sections, if you look up a datasheet of the regulator chip you should be able to find a reference schematic which will likely be very close to what's on the board. Not really cost effective when you factor in time but if you like fixing things it could be fun. |
