I guess you need to that the 7700 card and plug it into another computer that you know works and see if it does the same on it then you kinda know the card is at fault

well it seems funny you say the other cards work fine in the slot the 7700 don't

I got a new card here that don't work with a crt monitors but works fine with all the rest so its now on the junk pile and I kissed 240 bucks away over it

Could be a problem with the card or the motherboard.
That older, lower card could still work ok in both slots but it still be the motherbaord.

You need to test your 7770 in a different computer, or at least test an equal card in your computer. That will tell you if it is the card or the motherboard.

Also your PSU is garbage. Raidmax is unofficially called the "motherboard killer". There is a reason why it was so cheap, it was built to pass the 80+ test and not actually be a good long lasting psu.

I guess he just don't get it -- any thing could happen at any time and you seem to misinterpret ''funny'' above but as odd that the test card did work fine in the slot but now the 7700 don't

now you been told 2 time to test the 7700 on another computer to see if it has the samre issie on it then you kinda know its the card
