First off, please use punctuation. It makes it much easier to read.
Now, from reading your post, it appears as if you apparently installed a new hard drive, installed Windows 7 Ultimate 64, pc tools or something like that. Then, you left it alone and when you came back, it appeared to be in hibernation mode. However, it didn't respond to anything you tried (moving the mouse, typing on the keyboard, etc). Then, you unplugged it/turned off the power, removed the ups, removed the bios, etc. I sure hope you made sure first and foremost you statically discharged yourself before doing all that.
Have you tried to ensure that all power connectors are attached to your devices (hard drives, etc) as well as all data cables? I'm wondering if it's more of a loose connection somewhere on the hard drive that's set up to boot. In fact, when you added the 400 gb hard drive, did it replace what was already there or are you using the original as well as the new hard drive? Which drive did you install windows on?
If none of that works, you may have fried something.
