i'm not the best with computers, so last night i did a big boo-boo by putting my computer into a hard boot, while it was in the system restore program (because I wanted to cancel it-but couldn't).  Now my computer won't go through the complete windows startup.  It just continously reboots and when it gets to the windows startup screen (with the blue bars running across the bottom) and then there is a popping sound, and the computer reboots again.  When i try to get to the DOS prompt, it asks for a password, which I have no idea what it could be since I don't remember setting it.  Will someone please help?!

-Super WorriedIf you're using XP as you said then don't bother trying to get to DOS.  Try booting your system into SAFE MODE (when you start booting you should be given boot OPTIONS).  Hopefully once it's booted to SAFE you'll be ok.  If not, you might have to re-install Windows.You can attempt to use the last KNOWN good configuration from the Boot menu (F8 on startup) as well.boot to safe mode  as suggested but try this control panel/system/advanced/settings >startup and recovery/system failure/uncheck the automatically restart feature winxp does this by default if it incounters a problem...its tries this miserable and would better in the long run.. if it was to go back to safe mode instead..or SHUTDOWN and restart itself using the last good cab file it had...I reinstalled Windows XP and that seemed to repair the problem...
