It sounds as though that your checking other things and turning them off set it to open in safe mode with command prompt. If so you should be able to press ESC or type EXIT and hit enter to get out.

At this time because I am not really sure what you have done, let's concentrate on saving the files.....

The best way to do this now is to remove the harddrive and slave it to another computer. Once properly slaved, you will be able to transfer the files to either the other computer or to CD/DVD (which is what I would do).

The simplest way to slave a drive is to use a self powered external harddrive enclosure and plug it in by USB. You must determine what interface the HD has....either IEDE which uses the flat cable or heavy round cables (both using the 40 pin connector) to connect....or....SATA which uses a thin small cable to connect with. Once that is determined then all you need is the right enclosure...which can be used later on to house a newer drive to use as back up...

Note:
This could also be a sign of a bad harddrive...
start > control panel > admin tools > event viewer and check to see what errors are being shown and what application/hardware is associated with the issue....highlight the error and then click on it to see a better information of the error. Check all 3 of the applications in event viewer. if it is a bad drive you do not want to try to do anything but recover the files. Doing anything else could cause you to lose everything!
