I'm working on a computer that is acting rather strange. Here's a run-down of the basic symptoms I ran into: - Sometimes Windows XP will take a long time booting up (and sometimes will hang during this process) - Sometimes Windows XP will take a long time to shut down (and sometimes will hang here too) - While attempting to defrag, it stayed at 17% for a good 20 minutes before continuing - Compressing files on the disk using Disk Cleanup took a good 30 or 40 minutes I've worked with this computer before, and I can assure you that none of these things are normal. The computer isn't entirely unstable. When succeeding in booting, it appears otherwise to work flawlessly when using it. I am also told that the blue screen occured at one point, although it has never happened with me, so I don't know what it said. First I thought "hard disk must be going bye-bye". However, I can't seem to prove this one way or the other. I'm on the fence right now. I also considered configuration or driver issues. I tried things out in Safe Mode, but the problems persist there. I used a utility to test the RAM in the machine, and everything was okay there. I went back to my hard disk theory as that makes the most sense to me and is the most likely scenario. I attempted to backup the hard disk using Clonezilla. I have used it numerous times in the past to backup the drive. It did something funny when it was testing the drive that it has never done before. I took some pictures as I couldn't read the text that was quickly scrolling up the screen repeatedly: <a href="http://i625.photobucket.com/albums/tt338/saxman727/_CIMG4732.png" target="_blank">http://i625.photobucket.com/albums/tt338/s...7/_CIMG4732.png</a> <a href="http://i625.photobucket.com/albums/tt338/saxman727/_CIMG4728.png" target="_blank">http://i625.photobucket.com/albums/tt338/s...7/_CIMG4728.png</a> <a href="http://i625.photobucket.com/albums/tt338/saxman727/_CIMG4726.png" target="_blank">http://i625.photobucket.com/albums/tt338/s...7/_CIMG4726.png</a> It appears that it's having a hard time reading the disk...? However, after about 5 minutes of this, it finally brings me to the menu where I can select the type of backup operation I want to perform. The backup is successful with no bad sectors or other errors ever detected. So... now I'm stumped. I don't know if this drive is actually bad or not. The symptoms I would expect to be there aren't there. Could there be something else going on? Any ideas would be much appreciated! EDIT: It may be worth noting that I restarted the machine several times during testing, and at one point it didn't detect the keyboard, and one other time it didn't even detect the hard drive. In both cases though, the machine was restarted rather than shutdown. I know that sometimes freak things like that can happen if the RAM doesn't have a chance to clear out before booting again. Still, I thought these things were rather odd. They happened once each.
