I ran memtest tonight on all machines....
It gave 0 errors on all of them.....

So.... this leads to the conclusion that the memory is okay, and that
something else must be the problem.... Could it still be a failing power
supply or something? It seems both computers have a 230 W power supply.
Might be a problem, I guess, I can buy a 400 W thingy if that makes
sense.

Other solutions I heard:
- antistatic wrist strap: already have one :-)
- BIOS fiddling... What exactly should I look for? They are, as far as I
can see, identical memory sticks, probably both from different
suppliers, but besides that quite the same....
- are there different brands of memory of different quality and might
that be a possible cause of the problems? And if so - what are good
memory brands and what are the bad ones?
- I mixed different types of SDRAM... Could be it.... My mainboard
manual is not really clear about this.... And I have no clue what brand
of memory I bought... they are all 133 MHz SDRAM sticks, some 64 MB,
some 128 MB.... MB manual says it can handle all 64/128 MB sticks...
- <your solution here :-)>

Anyway, thanks for any advice until now and thanks for listening again,
hope to hear more solutions.
