If it's the memory you can try swapping RAM sticks or taking them out
altogether, if you have more than one.
Recently I saw these kind of MCE events also happen on a 3 year old
Athlon 2000 machine, which was on 24/7. There it finally turned out that
I ran an "athcool" program which enables powersaving mode on idle state.
Although this saves energy and reduces the fan noise, switching back to
work mode apparently wasn't fast enough anymore after these years. After
disabling the powersaving the MCE errors were gone.
The difference between these MCE's on memory or on the ACPI powersaving
(if you use that at all) is really simple to diagnose: for memory they
will occur on a very busy system, whereas the powersaving errors will
occur on a completely idle system.
But you might have real hardware problems of course. Then use the usual
routines: memtest(86), check the cooling, power surges, etc.
