Basically i have had my card for 1.5 years.
At first the card was fine but after a while i started seeing my screen cut out for micro seconds.
This started to occur when i started running a second display through my Amp/receiver for my TV
Finally my card randomly just failed and went made my monitor go black after switching to home theatre mode.

QUESTION: Is it bad to switch between monitors too often, like 2-3 times per day to watch tv on the big screen and to play games.

Does warranty cover this sort of this?

many 7970's have a dual bios switch. Try switch to the other bios see if it works. to use it, power off pc, switch the little black switch, power on and see if it works.

Intel i7-2600K, 8gb Ram, Radeon 7970, asus xonar essence stx sound card, Gigabyte GA-Z68AP-D3 Mobo.

Everytime i switched my screen would go black then on black then on black then on, im not sure if it was trying to adjust for the resolution of the amp, then reso for the tv.

Also this issue with my GPU blacking out has happened before but with my previous setup where i just connected my HDMI through the GPU to the AMP and then to my monitor with the other cable for got what its called the digital video output on. So that failed and had to use my mobo output to connect with my home theatre system.

I thought it would workout with the latter setup but apparently not.

Thanks for the help

Can you still get warranty if i lost the receipt of purchase? (i can probably find mine)

Yeah i tried that, also just a note my MOBO graphics doesnt work when the GPU is put in either of the GPU slots

My GPU now works with IGPU at the same time, but still the GPU isnt outputting anything

Is it werid that my monitor is black when the GPU is plugged in?

Is there any physical mechanism that controls shifting between GPU and IGPU? or GPUs HDMI/DVI-D? because i hear a clicking when i change stuff

No , If you plug the HDMI to the mobo then that's the Igpu if you plug it to the card then that's the main GPU

And yes its weird that your monitor is black , I suspect the GPU is dead but can't confirm.

Do you have any other gpu to try ?

Hmm i dont have another GPU 🙁 yeah its probably dead.

Whats RMA?

My spouse said she'd buy me a new GPU for xmas should i wait for a better card by then or just get the gtx980?
Thanks ill rate ur answer

RMA is to return the card to the manufacturer for a replacement , I think the 980 will be a good choice especially with your good CPU and PSU.

Thanks for rating my answer however I still want to make sure the card is dead , One last hope is to try plug different power cords to the card , your psu should have alternate 2x6+2 pin connections , maybe a clean installation of the drivers after uninstalling the older ones.

Uninstallation here : http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

Hopefully it'll work !!

if i were to SLI the gtx 980s do u think it would be worth upgrading my MOBO from my current rig?

I was doing some research the gtx 970 is much better price/performance + i might be able to afford sli with gtx 970 will probably go for that

zi had the same problem too but it turned out to be a faulty dvi cable. it started off as the screen going black randomly and mostly when playing games then blue dots started to appear and blue lines. The black screen would start to last longer and i'd sometimes get no image at all. I'm cheap so i doused the pins of my dvi cable in vinegar and it works fine now haha. Just dont assume its the gpu it could just be something cheap.

not sure how to specifically reply to u but YAY it worked ... kinda 😀

The resolution of the screen is 1080p but the screen isnt being completely used up its like a black box around my screen maybe 3cm deep, and the screen isnt crisp anymore. its werid driver issues?

What exactly went wrong that allowed switching bios switch make it work? thanks alot

Bios is one of the most sensitive components on a board, could have been a spike through the hdmi through your receiuver or something. What you can do, is download the latest bios from your gpu manufacturers website, and try reflash the other bios. You will need to set up a bootable usb (or floppy disk if your old school) with atiflash tool on it. Once booted to dos prompt switch the bios switch back to the other bios and flash the broken bios. It may be able to be recovered. If not you will have to limp along on the backup bios till you can get a new card.
There are a few guides around showing how to do this.

I have done this to flash my 7970 to the newer ghz7970 increased clock speeds and vcore. I recommend you just use the stock bios first to see if you can get it going.
