Aspire 5920-6423 Boot Loops before reaching POST

I have an Aspire 5920-6423 that I am working on for a client and the device will boot loop (IE: device power light will come on for about 2 seconds and go off for 2 seconds... and repeat) multiple times (IE: anywhere from 3-10 {no constant number}) before it POSTs and actually starts up. I have never been a whitness to this problem and am stuck between a rock and a hard place with it... Once it starts up, the system runs fine and will continue doing so until shut down or dead battery.

Course of action performed:

Fully charged battery, plugged into AC power... no fix

Fully charged battery, not plugged into AC power... no fix

No battery attached, plugged into AC power... no fix

No battery attached, no hard drive attached, and for giggles no ram attached... still boot looped, but did obviously get an error about ram.

Any guidance on this issue will come as a blessing.

Thanks!

at this point i suspect:

some CPU issue
motherboard hardware issue

i don't have other ideas.

check CMOS battery voltage

Are the date and time correct when boot with no network connection ? Bad CMOS battery will not maintain the clock correctly.

Followed directions as listed... Battery has a voltage of 2.9v so I am good there... Didn't get concerned about checking date or time since that is unrelated to the problem entirely. I went ahead and made a video of the problem and posted it to YouTube...
