Won't Power On. Nothing.

Really would like some advice, help, anything???
It's one of old AAO with 1gb ram and 8gb ssd. Installed Ubuntu 10.10. AWESOME!
Recently, I put new PNY 1gb DDR2 PC2-5300 into RAM.
When tried to pwr on, nothing happens.
No Lights, No sounds, DOes NOTHING. Removed cover and assured I was actually pressing the power button since I had had it apart, but nothing.
When batt installed, batt light flickers - off - on.
Pwr cable installed, Pwr light - on- green.
Attempted the USB BIOS update (FN - ESC keys) from info I found online. It does nothing.
I have removed PNY ram, Reinstalled original, and tried with none inserted, to no avail.
I haven't taken of the board the pwr button is on, Don't plan on it.
Any info appreciated.
Thank You

 

Well, if anyone's curious what I did (or what I didn't do) it's fixed.
Didnt have the board with the power button & etc plugged in to MB.
WOW. Better QC?
Anyway, its been working fine, just jumped back on here cause of new update to Linpus Lite and want to try that.
