Fan spins, no display?

post #1 of 18
Thread Starter 
I got a brand new 4850 for free but it doesn't work. Its a Powercolor 4850 512MB, the fan spins but I see no display. This is the first ATI/AMD card I'm getting my hands on, so I really have no idea what the problem could be as it is a new card.

What do you mean by there is no display? What program are you using to monitor this? If the fan is spinning you shouldn't have to much to worry about if you aren't OCing it. the temps of that card will stay pretty low during use as long as the fan is running at it's normal 20-25%.

Seems stupid, but did you plug the PCI-E power cable in?

I did. Also tried the DVI in both slots, didn't work.

Are you getting a beep from the speaker when you start it up? Wait, I just noticed you're caseless so I guess you don't lol... Does it boot with a different card?

If there is no display but the fan is spinning up... That's not a good sign, maybe the card still isn't getting enough power to fully boot up. I would try connecting a different power connector to if and maybe if it's linked to a different rail on your PSU it'll boot it?

I had a similar problem and it ended up being a bad stick of RAM.

I've tried everything from changing the 6-pin to reseating the HSF. My 8800GTS works fine, I'm on it right now. Two red lights flash as soon as I switch it on with 100% fan for a second or two after that fan reduces to default speed and nothing comes up on the screen.
