Last night I got it back to starting up with only one stick of 1GB,
but the screen stayed blank.
Today I did a bios reset (as suggested by Brian, but screen still stayed blank. Replaced
the original 2x512MB sticks and hey presto, system is now back up
working.
Looks like one or both 1GB sticks could be faulty. Interestingly,
the were bought on the same day, but are two different
manufacturers. Back to Novatech next week!
Thanks to Nick and Brian
