I have a vaio laptop VGN-FJ270 thats about a year and a half old. I decided to upgrade the ram from 1gb to 2gb. I put the new ram in and tried to reboot but all i got was a black screen. I've already tried putting the cards in the different slots, and putting the old ram back in. Nothing has worked so far. The computer shows the power is on, but it wont boot to any screen and i dont think the leds are even on. Any suggestions would be greatly appreciated
