I haven't put a new graphics card in it. It has been running fine for about a year. The motherboard was replaced about 6 months ago and along with it RAM since it uses DRAM2 instead of DRAM. It just stopped working.
I didn't think it would be RAM because usually I'd at least get some display or a post error but I get nothing.
If it was the motherboard, would it still show the network drives on the network after you let it set for a bit (time period for a normal bootup)?
I did think about Power Supply but everything looks like it is powered on and good. But could still be the power supply. Just figured graphics since it seems to boot and no video display, but monitor does test fine.
