I'm having a new issue. I recently upgraded the RAM to 4MB but now occasionally if I leave the computer sitting for a minute and I move or click the mouse or at random points when I'm using the computer, the computer will freeze and give me an error message flashing repetitively on the screen with no specific error code. I'm not sure if it's because I didn't reconnect the logic board correctly or if the pins are dirty or something of that sort. This didn't happen when I had only 1MB of RAM installed though.
