XPS M1210 - Dell Media Direct caused Vista to stop starting up?

i never use media direct, although i did set it up a few months ago, last night i accidentally pushed the button and it launched and froze. i had to hold the power button and shut down the system. now Vista will not start up (it ran the Dell intro screen, then flashed a blue screen and back to the Dell intro screen), in normal or safe mode. i ran the autorepair feature, it said it found and repaired a hard drive error. after that it would get past the Dell screen and into the Microsoft screen that shows the little green bar loading and goes to a black screen with just my mouse curser. I can move around the mouse, but can't do anything else (no ctrl+alt+delete, no anything). Has anyone seen this before? Any other advice before I try to reinstall Vista?

Thanks!

Either way try both buttons a few times.

 

Thanks for the advice, I've tried pressing both the MD button and the House(power) buttons- both do their functions (MD load MD, House turns on system) but both take me to a black screen with just my cursor visible, although in the MD screen I can bring up the task manager through ctrl alt del...
