I had not defragmented my computer in a while and Im not sure why Windows hadn't done it for me. It is still scheduled for every Wednesday at 1 am. When i manually ran the defrag myself(15% was fragmented out of 600GB, I'm only using 20%), it took over 12 hours and was still on pass one. So I looked into other alternatives. I stumbled across Defraggler. I ran that and it discovered that there was 17% fragmentation and it would take over a day to perform. I decided to just deal with having to wait, so I ran the defrag. I left it run over night, switching the power settings to performance and even double checked to be sure that the monitor and HD would not shut down for any reason.
When I checked on it in the morning (7 hours later), I found that it had frozen. Tried cntrl+alt+del and got no response. So I had to power off the tower by pressing the power button. Tried running it again when I actually had time to check up on it, and it ran for about 12 hours before freezing again. Mind you, it was making progress, I was down to 12% fragmentation at this time. I powered it down yet again and decided that I would let windows do the next one since I had never had problems with it. It displayed 6% fragmentation and within an hour had finished.
I then analyzed with Defraggler because I had read that it picks up other files that the Windows defrag will not (e.x.- >64MB). Well, it showed that it was 8%fragmented and that it would take 4 hours to defrag. So I ran it, and 6 hours later it said 4 hours still, but it was still making progress. By this time it was 2 am and I was tired, so I set an alarm to check on it.
I woke up at 8 am and checked on it, all I had was a black screen and the monitor stating that it had no signal, but the computer was still on. So I played with the video cord, tried a different monitor, tried a different cord, tried hooking it up to the motherboard videocard, tried pulling the bios battery for 10min, tried F8, F9, and F11. It seems to boot up normally (dvd drive blinks, all fans start up, etc.) but it will not send a video signal. There are no beeps coming from the motherboard speaker and no noise from the regular speakers.
I can not find the OS disk and had not been given or made backup disks. I do have the OS disk somewhere but we had recently moved, so it may take a while to find. I also tried opening the disk drive and it will open but then shuts itself right away. Also, I can not even get to the bios so any help to get me to a previous restore point or anything would be great.
Thanks in advance.
p.s. - Im using my macbook right now, so if that helps in anyway.
EDIT: I installed a new video card that I know works, and same problem.. It just boggles my mind that a defrag could harm your computer, nobody seems to believe that it can. Also, the computer was not connected to any network during the defrag processes, if that also helps.
