Virtualization Station with W2012r2

[yuccaone]

Hi,
I have an TVS-1282 with SSD and I make a Windows 2012 R2 VM with Virtualization Station.

All works fine for months since I launch my last image on July 2018.
But, last week (on friday), I stop this VM to reboot my Qnap. On the boot, I have a material message from front panel : BIOS : qx80ar20em - Checking memory and it doesn't start.
So, I push power button to stop my Qnap and start again : my Qnap starts normally but, when I start the VM, I have my VM from the state on July 2018 and not from the moment I stop it : so, I lost some datas (fortunately, I have some backup).

So, I have some questions :
- why I have that "issue"
- how my VM can start from a previous version ?
- what can I do to prevent this situation ?


Thanks

How much/what data was lost?
Are you using compatible RAM?

Did VS respond to disable, better to disable than reboot?

Hi,
Thanks for your return.

I'm upgrade the RAM too the max (64 Go) with compatible RAM : it's the first time I have this message.

For the datas, all work from july 2018 to friday. As I made the VM startup auto, it's like the VM start with my first VM image. In log file of VS, nothing appear (until my stop and start VM).

Thanks
