Why is my HeroBox randomly Crashing / Freezing up?

I love the HeroBox whe its running its got plenty of power for a little side file server, but after running it for a day or so the screensaver will just freeze and I can’t login or cntrl alt del or anything and have to do a forced shut down, after that if I press the power button nothing happens I have to un plug the power then re turn it on? I tried using a driver app driver booster to update all the drivers and then it ran great for a few weeks I thought I solved the problem but now she is randomly locking up on me any ideas?
