DX580G Problem: Have been using my DX580G MB for months, but the monitor went blank last night while using the desktop. This morning, swapped monitors, then graphics adapters, but no change. Pulled off the access door on the desktop, and found I am not getting any speaker beeps, front panel LED (blinking or otherwise), or any Port 80h POST codes. I have removed the graphics adapter, and all DRAM. No change. Power supply seems OK, as the graphics adapter, HDDs, system and CPU fans, etc. power up. The MB reset and power switches light. Any troubleshooting help?
First of all, I would like to inform you that this motherboard has been out of support since June, 2013.
However, let me provide you some troubleshooting steps that you may want to try.
