Okay will try that - rang crucial and they said that there might be a incompatibilty problemn with the board and memory and they are taking it to their technical people because i ran memtest and got no errors and they said and let me quote "
"it is possible that it will work fine for a few days then just suddenly not and memtest shows no erriors because there is nout wrong with the
ram and if there is something with compatibilty will will give you a replacement 4gb
ram of much lower speed"
i was like what the hell??? well i didnt say that but thats what i tought - they said they will email me tomorrow.
god my luck with computers is so bad - i recently send back my laptop for repairs and when i got it back it was even worse so i sent it back again only to find sum idiot forgot to plug the fan in!!!
anyways will remove the cmods for a while.
