With current hardware prices you are probably better off just replacing 
anything that doesn't work right, especially intermittently because 
you'll never know when you can trust it.   I wasted a lot of time with a 
machine that had a RAM problem (took days of memtest86 to show it) and 
even after it was fixed the problems kept popping back up as the 
alternate copy of raid mirrors were read.
