I upgraded from a 5400 to my 6000 I got from newegg started the computer it was slow bringing stuff up then I didn't have a keyboard when I got to OS selection so it went to vista. I got the black loading screen with the status bar then a black screen and that was it. I restarted and now no post and an error --. I will be testing the gpu tomorrow. I didn't want to tear this computer apart tonight and take the gpu out and put it in the other computer. But I may need a replacement mobo if this one is fried. I just got it for $40 from someone on pcper a week or so ago fresh from rma. But I really want to upgrade this box also. Id prefer a board that has true x32 and not one slot @ 16x and the other @ 8x or worse both slots at 8x in sli.
