I have had problems like this when memory modules or the CPU have had 
contact problems.

Just removing them and putting them back has helped in some cases. I 
needed new memory modules in the other cases.

I think it was just luck not to access the brocken module.

Can you test your machine with different modules or just take some 
modules out?
