I have an XPS 8930, out of warranty in 2019 which powers up, and the LED is solid white, but there's no video or beep code.  I've swapped the power supply, RAM, and video with no change. If I pull the RAM I get two amber blinks on the LED, so the diagnostics appear to be working. I'm thinking it's the motherboard, but is there a way to diagnose accurately? If it is the motherboard, can I get a motherboard from Dell?
XPS 8930, white LED, no video or beeps
