I once had a mup.sys problem that turned out to be a RAM issue. It took some
working out though, I only found out that it was RAM *after* I replaced the
graphics card. :-/

I suggest cleaning the RAM slots with an artists paint brush, then spraying
plenty of CO cleaner into them and letting it run out (if you have it, it
costs more than single malt these days) and cleaning the RAM module contacts
with a clean pencil eraser. Then multiple insertion / removal cycles of the
RAM modules sometimes helps if the first mention 'fix' doesn't do the job.

IME it's rarely the RAM itself, rather the contacts. Best of luck.

into you." Friedrich Wilhelm Nietzsche
