Yes, bad RAM, CPU, overheating or something like that can cause a 
machine check.

ECC on the memory can do a lot to avoid crashes, but sometimes you get
a machinecheck anyway.

How about cleaning the machine (dust is bad for cooling) & reseating
the memory? I cannot tell from here, but it has fixed problems for me
in the past.
