Based on current weather conditions(HOT) and the odd butterfly
effect..., I would say overheating is the most likely cause.
Check that all the fans are working well, and don't have dust in them
and there is good air flow through them.
Another option is the paste between the fan and the CPU drying out and
going too powdery.
I had a similar problem, and replacing the CPU paste and cleaning the
fan fixed the problem.
The result was a CPU that ran 15 degrees cooler.
I now set the HD to automatically spin down after 20 mins of no use
for temperature reasons.

The PSU has already span up the HD and read the grub boot sector, so I
don't think the PSU is at fault.
