Is Ghost same as Windows Image

Different imaging programs can have different formats, so you can't use one to make the image and the tools from the other to restore it.

If you have both the old and the new disk connected at the same time, you can do a direct copy from disk to disk, called 'cloning'. Some imaging programs can do that also.

basically you need to find out why the drive is slow. Is the current drive too full, too many temporary files, etc... otherwise if you transfer the drive image to a new drive or computer, you could also be transferring the problem.

I'll give a nod to the Apricom kits that run under 30 bucks.

But you have Eset so I googled this: https://www.google.com/#q=eset%20slows%20down%20computer

So maybe nothing wrong with the PC. Since Windows 7 has a free AV from Microsoft, we can for a test run run just the OS and it's own protection to see how that flies.

Also, scan it with Grif's help at http://www.cnet.com/forums/discussions/how-to-remove-pup-option-603542/#post-f742c795-5881-433b-a29b-6d758efe5cd3

Whatever image prog you decide to use you might want to test it.

Consider.....the hdd decides to quit.
You replace the hdd but you find that the image prog restore function is busted.
Now what?
