I just received my Crucial 4gb mem kit. I popped it in, put everything back together...pressed the power button...NOTHING. The chime went off, but black screen, then every 5 secs or so the front light blinked 3 times. I was pissed so I took it out and installed the stock (Samsung FTW) ram. pressed the power button. SAME THING!!!!! I CAN'T USE MY COMPUTER OR GET IT TO TURN ON!!!!!! WHAT DO I DO!??!?!?!
