Check that you hooked up all the power supply connections. Try a new motherboard battery as the old one may be dead and the bios is not working. You are evidently not getting a post beep signaling that the cpu, ram, video are good.

Three beeps at POST (startup) may be caused by an issue with your video card. Check to make sure the video card is seated correctly. If you have another video card, you can try it to determine if the current video card is faulty.

Installed new DIMM memory in Compaq D510 CMT - puff of smoke


Here's a full list of the POST beeps for your computer:

http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c00704816/c00704816.pdf

That flashing numlock and beep pattern says there is no system memory. When you let the smoke out before it might have been fatal for something. It could be the memory itself is dead, or something could have been damaged on the system board that is keeping it from detecting memory. The only way to know for sure is to try another stick of known good memory.

There's also the possibility you used the wrong kind of memory when you added the new part. Here's a link to the hardware guide for the computer:

http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c00706221/c00706221.pdf

You can use the information to be sure any memory you get is supported.

Hope this helps you. Good luck getting the computer running.
