A common cause of exploding PSU is bad caps in there. That can also
lead to failure of the capacitors on the mainboard.

Oh.

To make a long story short, I bought a new psu and installed it and am
keeping my fingers crossed.

That should rule out a PSU problem and hopefully cure the reboots.

So far so good; up several hours now without rebooting.

I'll let you know if the machine explodes on me.

Have you checked for bad caps on the mainboard ? They can often cause
spontaneous reboots. Particularly the ones in the CPU PSU. The bad
ones usually get much hotter than the others.

I don't know what caps are, so I couldn't check for bad ones. What do
they look like when they're bad (or good)? Do you check them visually,
or some other way?
