we were trying to add a vid card to his comp and the power cord(there is only the one for a second hard drive that is free) pulled on where it was hooked up to the HDD. it pulled ut about 1.4inch. do you think this could fry a HDD. it wouldnt spin up but you could hear stuff in the back. or do you think there just wanst aenough power for both the vid card and HDD. 250w psu. thanks
