Memory chips gone bad? Power (or other) cables gone loose?
Memory failures will cause intermittent and mysterious things. Easy to test, too, just run memtest86 on it for a while. Do that before rebuilding. If memory is failing, corrupted data could be written to disk.
I had a Crucial DIMM fail spontaneously a couple of weeks ago. Working one minute, totally failed the next. The machine rebooted, for no visible reason. After it came back up, compiles failed, always with different errors and in different places.
Power supplies also fail, as do motherboards. These are both harder to swap out than memory, so test the memory first.
