Windows XP didnt start

[satyajit]

The OS of my computer is Windows XP.

When ever I start my computer it asks for a password.After giving the correct password the following message comes:
__________________________________________________ ___________
We apologize for the incovenience.......blah...blah.....
recent hardware or software change might have caused this.

If your computer stopped responding, restarted autometically.......
......................choose Last known good configuration....

If previous startup attempt was interrupted due to a power faliure.....
.................................................. .........Choose Start windows normally


Safe Mode
Safe Mode with Networking
Sahe mode with Command Prompt

Last Known Good Configuration (Your most........that worked)

Start Windows Normally
__________________________________________________ _________

I tried all the options but no luck.

When I choose "Start Windows Normally" the Windows XP logo comes up for a while, after that the screen becomes black and after that nothing happens.

When I choose "Safe Mode" or "Safe Mode with Command Prompt" the following item is diplayed on the screen:

multi (0)disk(0)rdisk(0)partition(1)\WINDOWS\FONTS\vgaoe n.fon
multi (0)disk(0)rdisk(0)partition(1)\WINDOWS\AppPatch\dr vmain.sdb
..................................................
.................................................. ...
.................................................. .
.................................................. ...
multi (0)disk(0)rdisk(0)partition(1)\WINDOWS\System32\Dr ivers\NDIS.sys
multi (0)disk(0)rdisk(0)partition(1)\WINDOWS\System32\Dr ivers\Mup.sys

The whole screen is then filled with such mesaages and nothing happens.



Does installing java software or Oracle10g can create a problem?

My computers configuration is 2.63GHz, 512 MB of RAM with a capacity of 80 GB

Please help me as soon as possible, because I have some very important files in my computer.

Sounds like it is a BSOD (Blue Screen of Death). If you hammer F8 after the post and before you get to the screen that says:

You should be able to choose another option that says:

Disable Automatic Restart on System Failure.

If you choose this option you should boot up as normal and then get a blue screen with an error message like this:

STOP 0x00000074 (0x00000003, 0x00000002, 0x80087000)

If you post that error code here, we can help you further.
