Hi Squid,
Thanks for the fast response. I did the check with Memtest86 and the RAM is fine, no errors. The problem with this image is that it doesn't let me chose a img backup.
The problem that I'm getting time to time is that when I'm installing a new software in a VM and require RESTART of the VM, then I'm getting Windows recovery screen. If I am using the GPU the keyboard is not working only the mouse, so I need to switch to VNC and select from there "Start Normally" and after that switch back to the GPU.
If I tried to chose recover your system after a image is given me the error attached in the picture down bellow.
It is a way how to put a backup image from another VM in his place. The VM that have problems now is named Windows 7 - software, and I have a clean backup from another VM named Windows 7 - Games. It is possible to do something like that ?
If anyone have any idea is welcome write it here.
