(1) I have 3.4 CGHz with 2Gb corsair 3200LL RAM and a 150Gb Raptor X drive and am trying to run flight simulator X on my system which has windows vista ultimate. the PC is saying there is not enough RAM and I went to the virtual memory tab and found there was 'no paging file' for the Raptor. I tried to turn on virtual memory but could not work out what figures to type in the minimum box and the other box. Could you please help? System is not overclocked and PSU is Globalwin Onyx 520 W, DFI 875 mobo, X800XT graphics card with latest drivers.
