Hello to everyone
I have Radeon hd 5770 and the problem is that its all 3 outputs 2dvi and 1 hdmi Is broken.
At first there was no signal on 1dvi and hdmi, so I connected my monitor to the second dvi and made it primary in windows and like that the problem was solved for me for 3 months. Until now!!!!!!! Now the second dvi is also broken (maybe) and dose not give signal to monitor!!!!! I don't know where is a problem...
Also need to know that card is clean from dust I cleaned it and there is no problems with over hit. Also my monitor is vga and I connect it with adaptor to dvi.
So if someone has any brilliant ideas how to solve problem without throwing this card to garbage, pleas share it :)
If this helps, I was rendering in 3d max when the card started failing and then monitor said no signal!!!

If the card began failing in the middle of a computing session, and you had not installed any new windows updates or drivers during that session, it just suddenly died, then it's probably just dead.

Take the side panel off and power up the computer. See if the fan on the GPU comes on.

If if does not, the card is probably either done had it, or the power supply is not supplying power to it.

If it does come on, turn the computer off, unplug the 6 pin power connector attached to the card, remove the card from the computer and check the motherboard slot to see if there are any burnt areas on the socket or on the contacts of the graphics card. If it all looks good, reinstall the card, making sure it's fully seated and locked in at the...

If it all looks good, reinstall the card, making sure it's fully seated and locked in at the back and reattach the 6 pin power connector to the card. Use a different 6 pin PCIe power connector if your PSU has more than one.

You might want to test the power supply to see if that's the problem. If you can use a multi-meter you can test it yourself using the following methods, if not, you can take it to a computer repair shop to be tested.

If the power supply tests ok, then it's likely just a failed card that needs to be RMA'd if still under warranty or replaced.

There's always a slight chance it could be the motherboard, sometimes, rarely, the slot can fail. If your motherboard has more than one x16 slot you can try it in another slot to see if that's the problem.
