I picked a HP Proliant ML330 G6 for free (no ram or HDDs) awhile ago. I have recently acquired ram and hdds to put in it but its now displaying the red internal PC health led but all internal LEDs say that there is nothing wrong with it. Does anyone have a clue as to what this could be? It used to work but wouldnt let me install an OS so i out it away for a project at another time but bringing it out this time and now it wont post.
