D520 Scroll Lock and Caps Lock flash in unison, won't boot

i have a Dell D520, replaced the motherboard and now the Scroll Lock and Caps Lock flash simultaneously, Num Lock is on constantly and that is all that happens: blank screen and not making a sound. Automatically turned itself off after 40-45 seconds. Thanks!

Check to make sure the cables to the screen are firmly seated.

Thanks for the quick response. I unplugged the display cable, removed the display, installed the display, reattached & re-routed the video cable & antennas, without changing symptoms. :(

Hello Gary,

Welcome to the Community,

This symptom is seen specially when the system is unable to recognize the memory modules installed. (i.e., Num lock On - Caps lock Flash - Scroll lock Flash)

Few basic things that we have be sure off are-

Make sure the Memory modules installed are compatible with the new motherboard.
If they are compatible, make sure they are seated correctly.
Try known good memory from another computer or replace the memory.

If none of these resolve the issue, you may have to get a new motherboard.
