I have a Hp-2103wb computer that i installed corsair vengeance 16gb of 1600 ram onto.It worked fine even though the motherboard said it had a limit of 8gb , but who cares right. Months pass and i put a 2500k to replace the pentium. the computer would boot but not display anything. later I took out half the ram as a recommendation and it was fine. i tested to see if the cpu collided with something, but then even the old cpu wouldn't display anything. Help would be helpful.
