Hi, This computer was working fine last I used it. It has been sitting in a corner for awhile and finally got a desk to set it up at. I plugged it in and all 4 lights on the back are green but there is no image at all on the monitor. Tested the monitor and it works fine. Replaced the graphics card with one that I know works and nothing. Tried the Win2k boot floppy and the Win2k CD and still nothing. Any ideas? Thanks in advance :-)
