Unable to progress past Windows XP splash screen.

My Dell Dimension 4400 P4 suddenly decided to switch off yesterday for no apparent reason. After about a minute the "Safe Mode" screen appeared but whichever option is clicked I am returned to this screen.

When the computer tries to BootUp the Windows XP screen is displayed but shortly afterwards "Safe Mode" together with the various options are on the screen again.

I have tried pressing F8 during the reboot and I have had a message displayed which is shown below:

1RQL-NOT-LESS-OR EQUAL
DISABLE BIOS
MEMORY OPTIONS CACHING or SHADOWING
STOP 0X0000000A
(OX00000166 OX00000002 OX00000000 0X804E59C3)

There does not seem to be any option to select any of the above.

My computer has not been giving any trouble and the only hardware installed recently was a USB 2.0 card about two weeks ago and I downloaded SP2 about 1 month ago, but again these two items did not present any problems.

I would be very grateful for any idea what the trouble may be.

probably 'Delete button' on computer start
then just save & exit
see if that does anything

Not clear if u tried this or not...

Enter the bios by pressing delte/F2/F5/F8 (depending on your machine) immeadiatly at start up. Find the reference to caching or shadowing and disable it.

Managed to get into the Bios but under which heading and where do I find Caching or Shadowing?

With thanks.

Try pressing F8 during post and selecting "Last known good configuration".

Thank you all for your help.

Yes I've pressed "Last known good configuration"
and then the computer tries to boot even showing the XP logo but then I am returned to the original "Safe Mode" option window again.

This happens repeatedly and I cannot get any further. Why is this?

Cheers.
