Dell Optiplex 380 starts up but doesn't display on the monitor

[mukisa23]

I have a dell optiplex 380 which i purchased about 3 months ago but now it starts but nothing is displayed on the monitor. When i insert the ram chip in one of the slots, it beeps and for the other slot, it doesn't beep but it still doesn't display anything. Please help me rectify this problem. Thank u

A lot of the recent Dell Optiplex computers... well most of the Dell Optiplex desktops have been trouble. Since yours is still new, contact Dell. Do not let anybody else work on it until the warranty work is over. They will send somebody to your house.
