A very strange thing happened, i was trying what you said regarding setting the 19" as main (which worked) but then i thought "why dont i try and run my old G-force card that i OC'ed to much on the ATI framework, so i erased all the nividia drivers and made a slap happy job of cleaning the reg files, put in my old
GFX card and before the usual point of black screen i got the "no ATI device connected" it switched to 16 bit colour and i was able to get enough time in to dl and install the new nivida drivers.
touch wood
