Hey. My dad's laptop suddenly stopped booting consistently, and now it won't boot at all. When I push the power button, the screen stays totally black - doesn't flash anything at all - the fan spins for a few seconds & it sounds like it's going to boot, but then it shuts off after 10 seconds. I pulled the hard drive and pushed the power button, same thing - no error message on the screen or anything. I checked the screen with a flashlight to see if the backlight or inverter had gone out, but NOTHING is displayed on screen at all - it is totally off/dead. I'm thinking maybe, maybe bad RAM? But we just put new RAM chips in not even a year ago.... What do you think is the problem?
