Why me 5670 1gb not working


Jan 20, 2011
ok heres my new problem i got greedy and took my 5670 from one of my computers and switched it to another they both have 5670 but one is 1gb and the other 512. the pc that has 512 is were i play most my games so i figured it would be wise to switch to the 1gb. but now the 1gb wont work. at start up it goes to windows 7 start up and then it blinks and says "display driver has stopped working" im so pissed off cause they both work on the other computer, both cards run smooth on the other non gaming computer. i even tried switching the rams i have 8gb. i moved them around and around then tried with just two nothing then just one and still nothing. please has anyone had this problem and solved it.
