i think the power supply is giving out. now i cant get the machine to fire up with the HDD connected. it powers on, then it starts going into a reboot every half second frenzy, after it does that a few times, the screen just fills with lines while the speaker goes pip-pip-pip-pip-pip.

then itll just quit.....

remove AC power cord, remove the HDD and plug AC cord back in, machine runs fine. soon as i connect HDD, the machine cant stay on. like its pulling too much power.
