My, one-year-old-computer was working flawless until yesterday. after turning it on it got stuck on the "Loading windows" screen. I tried again and same thing happened over and over again. Moreover, I couldn't boot windows in any other mode (safe mode etc.) and "fix my computer" option got stuck as well.
I tried booting from the original Windows 7 X64 disc and no use. It didn't even let me reinstall windows (got stuck after the "install windows screen").
My next guess was some hardware issue but I couldn't figure what part of the system was malfunctioning...

Is there a known reason for this to happen? is there a bootable diagnostic software I can run to check my hardware?

As for my system information:
OPS: windows 7 64bit
MB: Gigabyte GA-P55A-UD3
processor: Intel I7 860
Memory: 4 x 2gb DDR3 Adata
HD: 2X 1T Sata3 7200 64mb C.B WD (In Raid 1)
Graphics: Nvidia GeForce 250GTS Gigabyte

I got warranty for most parts so I can easily replace one part or another only I have no idea which...
Thanks!

Well...I would say that the hard drive is an obvious suspect...worth running the appropriate diagnostic test for the hard drive.

The RAID configuration is also an obvious suspect, IMO.

I broke the Raid configuration and checked the HDs one by one. Using a bootable win xp from cd with UBCD and "Paratition find and mount" program I managed to salvage my old data.
Now here's the starnge part, the data on the HDs wasn't the same. One of them actually had data a couple of months old, wihtout the recent changes I've made. Assuming they should've been the same (mirrored after-all) I suppose the raid config stopped some time ago and changes I've made were written only on one of them. I tried to load the system from just one of the hard drives but it wouldn't let me.

Does it have to be a physical problem in one of them (or the MB) or could it be just be a 1-time-failure that won't happen again?
Is it possible to duplicate the 'good' HD onto the other one and rebuild the Raid configuration without loosing the data?
(I noticed there was some software from western digital that would duplicate it or something like that...)
Since I managed to identify the paratitions and mount them, I started making a backup but I'm limited to 500kb/s with the trial version of "Paratiotion find and mount", is there another freeware that could do the job faster?

Thanks!

That program is a recovery program, designed to recover data from the hard which has otherwise become inaccessible.

There are tons of reocvery programs out there...they are not all created equal.

There is a free version of the software...from what you state, you seem to have trial version of the paid program.

Other programs you may want to try:

Recovery Software, Partition Table Doctor - http://www.ptdd.com/

Recuva - Undelete, Unerase, File and Disk Recovery - Free Download - http://www.piriform.com/recuva

Easeus Data Recovery Wizard
