Ignoring it doesn't help... DUH! Read/write failure? 
	
	
		I don't know why I thought this would "resolve" itself if I just carried on without making a fuss.  That's kind of like driving around with the fuel light on right until you run out of gas.  
I've got a Dell Latitude 610 laptop.  My fingermousing went out suddenly last week, and I started using a peripheral mouse, and now it has started jumping randomly around the page when I'm not even mousing.  I started getting this message last week: 
Memory write/read failure at 1FF00080, read FF12FF10 expecting FF10FF10
Memory address line failure at 1FFF0000, read FF12FF10 expecting 00000000
Memory write/read failure at 10000000, read 00ED00EF expecting 00EF00EF
Decreasing available memory.
Strike F1 key to continue, F2 to run the setup utility…
Are these related problems?  Will I have to seek professional help?  Because I can't, so if I do, I'm screwed.  And if I'm screwed, how long do you think I can limp along before it goes entirely?  Any guesses how to prolong the agony?
Thanks!
