Being that a new motherboard did not fix the problem, I would try these things next:
1) Swap the RAM and try again. Faulty memory will stop a PC dead in its tracks.
2) HP's and Compaq's are known to have issues if ANY of the cables are not plugged in all the way, or are in cocked at an angle. I have "saved" at least 4 HP/Compaqs just by unplugging and plugging the internal cables (like keyboard, mouse, power button board, LCD, etc). This is a lengthy process... but, hey; if it fixes it, why not? (don't forget to check the connector on the back of the LCD itself!
3) Unplug the battery and A/C power. Hold the power button for 30 seconds. On most laptops, this resets the charging/power circuits and can revive some dead laptops.
4) remove all non-necessary devices from the laptop and try booting again. These include: Hard Drive, CD-ROM, WiFi Card, Modem board, Keyboard, Touchpad, and anything else that isn't needed to boot. If it starts up with them removed, start putting them back in one at a time until it fails to boot again. That's your culprit.
Good luck, I hope that helps.
