I bought a HD radeon 7770 black edition gracphics card but I'm having problems with it, when i start the system i get a message saying: "The current input timing is not supported blah blah blah... please change resolution to 1280x1024 @ 60ghz" after that I get a white pixeled screen, I've tried using a different moniitor, different vga-dvi converter and i get the same result every time. I tried using an old nvidia 7200gs card i had and that one works ok, one thing that I want to point out is that when i start the computer the gpu fan starts really fast and then it goes slowly I don't konw if that gives you guys any clue... :??: 
Do you think that maybe the PSU is not enough, 475W ??
I'm avoiding to think that my gpu is dead :'( 
This is all my hardware:

Intel i7 870
8gb RAM 1333mhz
HD Radeon 7770 black edition
Cooler master EX2 475W power supply

I leave some screenshots if that's of any help..

It's a dell p190s, not the greatest looking monitor nor the best but it gets the job done.

Are you using VGA or DVI?

With the 7200GS plugged in, go into windows and change the display to 1280x1024 and 60Hz. Tell it no on the reboot. Shut down and plug the 7770 in. If this doesn't work you might want to try going into safe mode and remove all video card drivers with driver sweeper and load the newest AMD drivers.

I've tried that but the problem is that I don't even get the POST screen when the PC boots up so there is no way for me to select anything not even get to the BIOS, Right now I'm using the nvidia 7200gs with 1280x1024 @ 60ghz settings but when I try to boot with the 7770 the same problem happens again. :(

Sorry, I thought windows gave you the error message. Can you put the 7770 in there, reset the bios, then try booting?

Test it in different machine? Perhaps the card is bad.
