Monitor shows "out of range" on powering up the machine. Steps taken:

  • Visual inspection: no blown capacitors or any signs of burning/physical damage
    Unseated the card, took off heat-sink, cleaned it-applied fresh thermal paste on GPU and re-seated it
    Tried the card in different slots on the same MoBo
    Reset the CMOS by removing the battery and moving the jumper.
    Tried card in another machine: same result (out of range message)
Since there is no display whatsoever, there is nothing I can do.
Please don't reply with "buy a new card, bro" - I don't have the money.
Any suggestions on how I can positively confirm its a dead card/repair it? Flash the GPU BIOS perhaps?

DVI -> HDMI uses the same part of the card as the DVI port(both digital).

I am honestly grasping at straws(hoping its just a dvi issue) so you do not need to "obtain" another card. Hell some cards even have S-vid out(not that you would EVER want to use that on a pc screen)

By this point the 4770 has most likely has a good life.

If you have a system with onboard video you can see if the card is even detected(use the onboard video to do the test.).

If your screen has DVI and VGA, try whatever you are not currently using maybe part of the card is still working.

Unfortunate many of the ICs and the core it self can be damaged without you ever being able to tell with a visual inspection. If none of the other video out options work(with any luck just a port is blown and the rest of the card will keep working), the card may just be dead.

It was set to 1080p when the card blacked out. How can I change the screen resolution now? There is no display at all. I cant even enter the BIOS.

i would try to beg borrow or steal another card to see if it would sync up to check resolution,but this does seem to be a catch 22 situation.should be able to enter the bios.sounds like something else going on here.try resetting the cmos by either pulling the battery for a minute or so or by using the jumper if so equipped.

The problem is that video card resolution does NOT stick from Windows to the bios. No matter what you set it to in Windows, you should ALWAYS see the bios(and you can NOT change the bios resolution, but it is always rather low). If this was a Windows issue, It would take less than 1 min to fix(F8 -> Enable Low Resolution mode(640 x 480) -> adjust to native resolution in Windows)

If your screen has VGA, try a DVI -> VGA converter to see what it does. Almost all cards come with one.

If that fails, chances are the card has failed fully.

Agree with your point on resolution. Irrespective of the resolution set in Windows, the BIOS should show. Have a DVI to HDMI converter. Will try that out as well as DVI to VGA.

Indeed it has served me really well. No reason to complain.
I just wanna wait till ATI releases the next series of cards in Oct. before I make a purchase.
Oh well...

Tried DVI-VGA, DVI-HDMI and Composite Video with an RCA cable on my LCD TV. Nothing works. Each time the same result.
The card does have power and the fan is spinning but apart from that there's no display whatsoever.
