Using Windows 7 Pro on a domain. The hard drive was an OCZ Vertex 3 (which I never use anymore) 120GB. When I started using the computer, I noticed the mouse point was at the top of the screen. And, it was sort of shaking and moving by itself. Never had an issue with cross compatability with other mice or USB connectors. I rebooted the computer, which didn't help. I added a battery and rebooted again, and it then showed there was no hard drive.
I took out the OCZ and should have tried it in other computer (still can) to insure it wasn't the drive. But, I have some Samsung EVO SSDs 250GBs, so I traded that out. I could reinstall Win 7 Pro, but I really don't want to start all over.
So, I restored an image from Macrium which had been made two days prior using the Macrium boot DVD. I verified the image which said it was fine. I then restored, which also worked fine. I rebooted, and it could not find the hard drive. It would not boot into Windows. The only thing I can think of is that the boot sector of the older SSD was corrupted, and it was the one that was imaged. Thanks.
