Hi, This has happened since first use. I have latest drivers for Video card (GForce 7100GS) It crashes waking from sleep mode. I must admit I am new to Vista, but in Start Menu there is (L to R) the brown power button which says 'Puts your PC in low powermode etc. ( which I find odd as this is the Standard Power Icon for ON/Off??) Then the 'Lock' button, then the arrow button which gives various options, which I use to either shut down, or sleep the PC. If I 'wake' it (after entering sleep mode) it just crashes!!. Another point which may be connected is that on startup I get a dialogue box from IE saying there is a 'Scipt error, do I want to run with scripts?Yes or No' I select 'Yes' & carry on. I hope I have explained this adequately. Alex
