PC doesn't recognize my hard drive, Windows 7 Ult x64

[khoikn]

In an attempt to make more space for my media files, I created a new partition on my computer and simply moved all of the files from my previous 40Gig partition into my new 100Gig partition.
Everything was done using the built-in software that came with Windows 7 Ultimate.

Things went fine for a while, then I wasn't able to load my PC.
Fair enough, I reinstalled the OS.
It worked for a few hours, I installed all the updates into my system after the fresh install.
But when I turned it on in the morning, it worked for about 30 minutes and then I got a blue screen and it auto-restarted.

Now, I can't access Windows or even reinstall it.
The Windows installation disc doesn't recognize my hard drive anymore.
(It's an official disk that I got from my Dad whom works at a Microsoft partner company.)
