Windows XP Black Screen After Logo

[Ccucu]

Hello.

I usually don't ask for help as I seem to get most of the issues fixed myself, but this one is over my head

To begin with, these are my specs:
Motherboard: ASUS M2N rev 1.02g
Processor: AMD Athlon LE-1640 / 2600MHz
HDD: WD Caviar Blue 160 Gb
Power Supply: Delux 450W
Graphic Card: Nvidia GeForce 7300 LE 256M
RAM: 1024 DDR-2 800MHz Kingston

Now, Friday there was the cleaning lady in the office and unplugged the PC while it was started. I left it like that until Monday and in the morning it didn't start.
It starts normally, Windows logo appears, it is loading and after that it hangs on a black screen with no mouse cursor.

I tried:
- Replacing RAM
- Replacing Power Supply
- Replacing Video Card
- Install Repair of Windows XP with Original Disk
- Ran CHKDSK /r from recovery console
- Tried fixboot fixmbr from recovery console
- Scanned The Whole Filesystem with Kaspersky Rescue Disk
- I tried replacing the HDD with a new one, did a fresh install of windows XP and it works.

Now, I can't afford to lose data, so fresh install is not an option.

It doesn't start in safe mode, not in VGA mode, not in debugging mode.

I have resources I just need an idea on what to do from here.

Please help.

Thanks

If this is too elementary, let me know... Just not sure how basic you need the help to be.

I doubt all the hardware changes were required.
I suspect you "simply" ended up with a damaged windows installation from the loss of power.
(Hence the advisability of a UPS.)
With any luck you can still recover most of your data...
any files open at the time of power loss are likely damaged.

You have replaced the hard-drive and (re) installed windows on the new drive.

Your old drive is now out of the machine?
Or did you slave it and leave it in the machine?

If it is out of the machine, you can do the same with a USB enclosure for it.

From the new boot disk... boot,
and try to use Window's explorer to look at the old drive: Can you find files?
If so, transfer them to the new drive.
After you transfer your files, you can reinitialize the old hard drive, and...
either install it (for example) as a data-drive,
or use it as a usb drive for back-ups.
