Well, are you sure the battery is good? Sounds like a dead battery.
You should always power it off and 30/30/30 reset before changing parts. It's good form.
Power it off, unplug it. Try to turn it on for 30 seconds.
Do you have a battery tester? Test the CMOS battery make sure it is actually good.
How about overheating - has it been - Either CPU and/or GFX?
Onboard Graphics Card or AGP/PCI-E Graphics Card?
Is that everything you did in there - maybe bad RAM?
Did you disconnect and forget to reconnect any power supply cables?
Maybe the motherboard is bad - the RAM bank, or the Southbridge or SMBus? A reflow sometimes solves that...
Have you tried disconnecting all USB devices?
Did you unplug the video cable accidentally?
Listen, if you did most of those things, double check and make sure.
I would suggest lastly this.
Disassemble everything and reassemble everything. Don't mess with the CPU or CPU heatsink, but unplug the cables of it.
Remove the PCI cards, GFX card (if any), remove the RAM sticks, disconnect the power supply from EVERYTHING including the wall - I don't suggest you mess with the power switch and the etc that right there, try to leave that one plugged in, remove the CMOS battery, disconnect SATA/IDE.
We're talkin everything.
Once everything is disconnected, do a 303030reset. The only connected to the motherboard should be the power switch.
OH DAMN - check for maybe any dropped screws bouncing around in there. I've seen that a few times...
Then reconnect it all and spend the $7 or whatever and go where nearby sells those batteries. I like convenience, CVS works.
IF THAT DOESN'T WORK,
Do a step by step installation, starting with only 1 stick of RAM, power supply connected to all ports, no drives connected, etc and just try to get it to POST BOOT with as limited installation as possible.
That's how I would do it.
Then I would consider what could be damaged etc.

I provided a pretty comprehensive reply, anybody else is free to mention anything I may have missed.
Did you try anything I listed, or you expect a magic answer to fix your machine for you? Because you haven't replied to direct questions and then you voted it down.
Its not like I asked for a HiJackThis log, but also I don't have to put up with your lack of participation in your own repair.
If I could downvote you I would, because your question doesn't mention much and you refuse to reply when I ask for more information. It's a waste of my time, and I'll gladly help anybody else who actually needs help.
Keep pushing the power button, you obviously have it figured out yourself and don't need my help.
