Unable to boot up the computer - HELP ME!

[mechengr]

last night while i was surfing on the net, my computer got hanged over ten minutes, and it didn't give any response (only beep sound when i move the mouse), I couldn't do anything but switched off the power supply. However, the same situation happened and i switched off in the same way.

After four times of rebooting in that way, the computer stopped with the following error message:

"A problem has been detected and windows has been shut down to prevent damage

to your computer.

UNMOUNTABLE_BOOT_VOLUME

If this is the first time you've been this stop error screen,

restart your computer. If this screen appears again, follow

these steps:

Check to make sure any new hardware or software is properly installed.

If this is a new installation, ask your hardware or software manufacturer

for any windows updates you might need.

If problems continue, disable or remove any newly installed hardware

or software. Disable BIOS memory options such as caching or shadowing.

If you need to use safe mode to remove or disable components, restart

your computer, press F8 to select Advanced Startup options, and then

select safe mode.

***STOP: 0x000000ED (0x80F51820, 0xC0000032, 0x00000000, 0x00000000). "

Before the computer got hanged, i was only surfing on the net. Neither new software nor hardware had been installed. If so, probably my computer was hacked. I couldn't log to the safe mode or any other mode, all resulted in the same screen of error message.

Please kindly advise if i can boot up my computer again. I don't want to use the restore disk because i got lots of important files inside.

PLEASE HELP! Thanks so much!

Damaged File System

If the second parameter (0xbbbbbbbb) of the Stop error is 0xC0000032, then the file system is damaged.

The solution is below this on that page.

If this is the case, restart the computer to the Recovery Console, and then use the chkdsk /r command to repair the volume. After you repair the volume, check your hardware to isolate the cause of the file system damage.

To do this, use the following steps: 1. Start your computer with the Windows startup disks, or with the Windows CD-ROM if your computer can start from the CD-ROM drive.

2. When the Welcome to Setup screen appears, press R to select the repair option.

3. If you have a dual-boot or multiple-boot computer, select the Windows installation that you want to access from the Recovery Console.

4. Type the administrator password when you are prompted to do so.

NOTE: If no administrator password exists, press ENTER.

5. At the command prompt, on the drive where Windows is installed, type chkdsk /r, and then press ENTER.

6. At the command prompt, type exit, and then press ENTER to restart your computer.For additional information about how to use the Recovery Console in Windows XP, click the article number below to view the article in the Microsoft Knowledge Base:

314058 (http://support.microsoft.com/kb/314058/EN-US/) Description of the Windows XP Recovery Console

If this procedure does not work, repeat it and use the fixboot command in step 5 instead of the chkdsk /r command.

I have tried a suggestion from other technical help.

Making use of the Bootup disks and tried to make use of the "chkdsk /r" or "fixboot" command... under the Repair Console.

However both failed.

For "chkdsk /r", the file "autochk.exe" cannot be located.

For "fixboot", it doesn't have any help (though later i found that it's for X86-based computer)

And hence both resulted in the same error page mentioned in my original post.

Then I tried the "dir" command and found the error message "An error occured during directory renumeration".

So, I found that the bootup disks don't really help in this case.

Being exhausted, I inserted the Recovery Disk from Packard Bell, but just turn to the Dos prompt. When I use "dir" command, it showed something strange "Volume of Drive C is BACKUP".

From my liimited experience, I think it should be "Volume of Drive C is Window XP" (or similar).

Is that my harddisk crashed? but i used "scandisk" and it showed no error. Or is there any factory setting that locked the computer under invalid booting record (my power-off act)? or the Window XP disppeared?

Please help... I am so exhausted to go to the internet cafe.
