compaq presario cq61-420us will not reboot after shut down

Specs: Windows 7, AMD Athalon II Dual Core3GB
compaq presario cq61-420us will not reboot after shut down or if battery dies and it goes off. Pressing power button to reboot sounds as if it is turning on lights flash and fan starts for about 1 or 2 seconds and it shuts back off. I have tried unplugging and removing the battery and holding power down 30 seconds, but does not work. Out of panic began holding various keys with the power key and found that holding the control key and power button that it turned on. It has only been a few days since this problem surfaced and already its is taking several attempts to get it to turn on even with this method. I am afraid that eventually this option will not work either. Any suggestion on what part might be going bad that I could get this fixed before I lose it alltogether?

Things to look for:

- Was unit dropped, subjected to electrical spike?
- Is it Blue Screening or just powering off?
- Any error messages on screen?
- Any lights blinking, glowing on system? Any blinking light patterns/codes?
- Any sounds - beeps, beep codes, loud fans, grinding noises (fans or hard drives).
- Any smells from system - smoke, electrical?
- Check AC outlet unit is plugged into.
- Battery condition - is battery OK & charging?
- Check Power supply (test voltage and on another laptop if possible), cords, connectors (male). Test PSU on another laptop if possible.
- Test laptop power switch.
- Check AC power connector (female connector) on the motherboard (sometimes the connections break/crack).
- Motherboard (pull & inspect), check fans for debris, sticking or rough movement (bad bearings).
- Test HDD (may have to do this in another laptop or USB HDD adapter).
- Test RAM - pull RAM, test boot system to see if it recognizes lack of RAM. Add 1 Ram module back in one slot, test boot. Switch that ram module to other ram slot, test boot; do the same with any other RAM modules you have etc.
- Test/pull DVD/CD ROMS, floppy drives (if older unit).

MOOOOooove! OH and you're welcome!
