Ok I started running memtest, but I'm not sure exactly how to use it.  
First, I tried memtest 100m --log, but that pretty much stopped the  
computer from doing anything else. So, I stopped that test and put it  
to 50m. But am I doing this right? Oh, by the way I think I have  
somewhere around 120 Mb RAM
