I buy this card from Fry 's since the video card I have currently in my p4 be only 64 meg and can not play hidef video . after I install the card , window no longer boot . I try reseed the card , no luck , window still do not boot . I put the old video card back in , and window load normally . I try put the new video card in and again , after post run , nothing happen , window do not load , just a blinking cursor . I be go to return this card and try a different brand .
