hey guys, hope you can help me with this one because its annoying the hell out of me.

my comp reset the other night, and i couldn't boot it back up. for the first time ever since owning the computer, i now see an advertisement for the corecell as soon as the comp starts up. the media check which comes up before xp loads is now gone, and after the xp loading thing comes up with the blue bar, it boots into a black screen.

i've tried booting it in safe mode, but safe mode comes up with a black screen as well (minus the words safe mode in the corners).

please help!
