Current Info:

The computer stopped working in July 2015, when the same issue above happened. It was kept because we thought it could still have a chance at working again. On August 8, 2015, I turned on the computer, and it worked and loaded no problem, although the Windows 7 OS which was last used OS on their before it stopped working couldn’t boot. The only Windows copies I had in my reach was Windows XP Professional Service Pack 3 and Windows Vista Business Service Pack. I used Windows Vista because it was newer and since Windows XP is no longer supported I knew I couldn’t get supported drivers. When I installed Windows Vista it took 30 – 40 minutes but in the end it worked at the computer was completely useful. But while I was working I got Vista’s “Blue Screen of Death” twice and at about 8:36PM it froze completely so I shut it off and when I turned it on it wouldn’t boot. I tried to start it again two days later and it worked It booted, I logged in no problem and then five minutes later, BLUE SCREEN OF DEATH!!!. And here I am currently with it now not booting at all. When I turn it on now I hear the hard drive trying to boot but failing. And this is what’s currently happening.
