Hi Thanks for all the info I tried a few combinations of the advice given, and finnaly got it all working ok. For your info this is what I did. I removed one of the 512 meg ram sticks safe booted & installed the older version of nVidia reference driver, version 21.83. That managed to boot properly and configue graphics card ok. I then inserted the 2 lines MinFileCache=51200 & MaxFileCache=56320 into system.ini under vcache heading. Again rebooted all seemed ok Replaced the ram Rebooted and all seems well Thanks again.
