no signal detected

[qdudfff]

I have a BenQ ZOWIE XL2430 144Hz and when i connect my gpu (amd sapphire tri-x r9 280x) or my cpu (intel i5 4690) to it, it just flashes no signal detected (using a dvi d dual link).

yes for like 3-5 years (changed my thermal paste for both because the cpu startde to overheat) and after that it worked and was fine until i turned on a game and the moniter just went black,

see now that kind of information being left out of the post , doesn't help us at all. include that so we know what's happening.

pull out the gpu entirely and reset the motherboards bios and try to get it working with the gpu removed. no sense in trying to get the gpu working if the board won't post by itself.

so done everything and it works fine without the gpu (if i insert the gpu back it goes back to the flashing screen with the No Signal Detected)

well you may have very well bricked the gpu

the only thing i can think of is to manually set the bios to use the onboard gpu and not the pci-e gpu with the card installed. see if it will boot like that with the monitor plugged into the motherboard , then see if windows can detect the card and install it's drivers.

otherwise yeah the card could be bricked , I used to have an r9 290 back in the day and it was the worst gpu i ever owned from a reliability standpoint so it's not impossible.

well long story short the gpu is dead, Ty for the help will try to fix the gpu or buy a new one
