I'm not clear on your problem. Does it lock up, or does it give you SYNTAX 
ERRORs? Does this happen immediately at power-on, or does it work 
perfectly for a few minutes?

Does it do this with =no= cards installed? If so, then my first thought is 
that it may have a bad RAM chip. (Of course, it could be a lot of other 
things, also.)  One way to check the RAM is to rotate the rows of chips. 
If it is just one chip, then the problem should change.

Good luck.
