well, I went ahead and bought the stick of ram, and it's a no go. didn't help at all.
I have helped people make computers all the time for other people, and have had no problems, this is the first i've ever done for me, and it's been a disaster. uhg. yes, i've checked all cables, tried different monitors, all the monitors do work on another computer, i've even swapped the 5200 for a geforce2mx that I KNOW works, just to get the same result.
