MacMini Late 2009 randomly restarting

Hello all,

My late 2009 MacMini is randomly restarting. I have been trying to understand if it's happening when I open a specific software or open a game such as FreeCell.
Last week there was a short power outage on in my neighbourhood and I'm also considering if this could have caused a particular problem.
I have already booted in the Recovery Mode and ran the Disk Utilities / First Aid / Verify Disk Permissions / and indeed there were some files that were successfully repaired via Repair Disk Permissions.

Do you have any other good idea of what could be causing this instability.?
Thank you very much indeed.

Here are two panic reports:
