Hi guys, Recently,I opened my laptop to fix the left mouse button and somehow I did something and when I start my laptop with both of my 512kb memory cards properly in their spots, the computer just has a black screen.Also, you know those lights that are lid to the left of the power button, the 2nd & 3rd lights from the left just flash constantly and the screen is black as I said before. The first light from the left is solid green. Does anyone know what this means and I hope I made some sense here.I basically had to take out one of the memories off and my laptop starts just fine.This stuff I told you only happens when I put this other memory card into it's spot. Any help would be very much appreciated.
