After chkdsk /f system cannot restart

[morulis]

I have Windows XP Service Pack 2. I have two accounts one with Admin privileges and one with limited privileges.

I did the following:

1)As admin I wrote in the Command Line: chkdsk /f
2)In the message that says to schedule a check I answered "yes"
3)I restarted the system.
4)The check is done and completed without problems.
5)After that it tries to reboot
6)I see the Windows XP logo but suddenly
7)A black (not blue) screen tells me to select if want to go in safe mode or start windows normally or start the last good configuration.

If I select start windows normally the checkdisk is done again and the same screen appears after the restart.

If I select the last good configuration the system goes ok.

I've tried to make chkdsk /f other times too but I hadn't that problem(Note: All the previous time I had only one account with admin privileges).

Please help!

I add some more information about the problem. When I try to make
chkdsk /f, after the checking is finished and the computer is restarted
I receive the following message:

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

SESSION5_INITIALIZATION_FAILED

If this is the first time you've seen 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 component, restart
your computer , press F8 to select Advanced Startup Options and the
select Safe Mode.

Technical Information

STOP: 0x00000071(0x00000000,0x00000000,0x00000000,0x00000000)"

After I restart my computer another screen appears which prompts me to
select Safe Mode or Last Good Know Configuration or to Start Windows
Normally. If I select Start Windows Normally then the same thing
happens. If I select Last Good Known Configuration the computert logs
in.

What's the problem? Before Service Pack 2 I don't think that I had
that problem.
Is there any virus? How can I solve the problem?

Most likely cause is a bad or corrupted format on the hard disk.

You may want to download the Diagnostic disk from the hard drive
manufacturer and run that to test for possible damage to the drive.

Unfortunately the fix is a reformat - fresh install.

Instead of chkdsk /f, run chkdsk /r. This is a little variation on the /f switch and will many times find and fix more problems. observe the entire process (yes, I know it is boring) to see what errors it finds and under which section they are.

Do you have PCAnywhere v10.5 installed? There is a problem with one of the files. I replaced the offending file with an updated version from Symantec and the problem was solved.
