I was installing wincleaner one click .I left it to installed came back and the hard drive was running hard . I shut down ( improper way). Booted back up and it was working. I left and for short minute and the power light was blinking did not come back up . I took the power source in and had it tested and that came out OK. they said try to take out one stick of the ram and make sure . I booted up and the screen came up boot to CD. when I putting the power source back together I did not plug the hard drive to it . It will boot if i do not have the hard drive once i plug the hard drive it would not to anything .This is my operating system vista . my question is if i replace the hard drive as that seems to be the issue and gateway CD is operating system disk will this put vista back , I know that i will not have anything on that hard drive as I will be replacing just want a running system. see attached information on the system.
