Is yours a SFF model 780? Overheating can cause freezing, and small case 
Dells, like other compact case PCs, are particularly susceptible to 
overheating if allowed to accumulated dust and/or tobacco tar, particularly 
on CPU cooler and/or within PS. Dust collected on tar acts as an insulator, 
containing heat within the source components. If you're sure overheating is 
not your problem, run memtest86 overnight or longer. You might have failing 
RAM. It happens. Sometimes simply reseating RAM will help if testing produces 
errors, but don't count on it.

I can't recall my SFF 780 ever doing as yours with any Linux kernel all the 
way back to 3.11.7 and up through 4.5.4, and servers 1.14.x through 1.18.3.
