I had tried to add more memory but I didnt get right one so i replaced old one. I thought it would all return to normal but nope. There is no video. First thing i did was tried the Ti4200 on my old dell and it works fine, so than I tried video card from the dell but still no video. Asked some folks they told me reset bios,onboard video, make sure ram is snapped in, and wires are all connected but no video. I mean all three keyboard lights flash green, power button is green, MOFO light is green, light on PSU is green, fans all work, what am I missing guys?
