Ok here goes

One of the klids (very likely the youngest) left the computer on last night. Hubby noticed this morning, says there is funny squiggly lines on it. Shouts at kids.

Youngest turns off the computer at the button doesn't actually log off first.

Now when you switch on you get the following message:

We apologise for the inconvenience, but windows did not start successfully. A recent software or hardware change might have caused this.
If computer stopped responding, restarted unexpectedly or was automatically shut down to protect your files and folders, choose last known configuration to revert to the most recent settings that work.

If a previous start up attempt was interrupted due to power failure or because the power or reset buttons was pressed or if you are not sure what caused the problem start windows automatically.

Safe mode
safe mode with command prompt
Safe mode with networking
last known configuration
start windows normally

Right I have tried all of the above yet it just keeps restarting and showing that screen again. I tried to reboot using my disk but get that screen again.

It is Windows XP

Any ideas?

Thanks in advance.

BTW laptop not very reliable so until I get computer sorted may not be around for some time so would appreciate help to get me back online.
