Is my GPU dying ?

RIP I'm no professional so I don't actually know, but I do hope you figure it out, Tempete. <3

I really doubt a PSU issue could cause this kind of glitch, but it does sound like the port in the GPU could be faulty/burnt. Have you tried to boot in safe mode to make sure it isn't a driver's issue? Maybe you can connect your GPU to your monitor using a different kind of port?

If you see a lot of graphical artifacts on screen, then it's very likely that it is the GPU. Check to see if there's anything physically wrong with it (like any damaged caps). The only way to really make sure that that's where the issue is would be to find another GPU and test that in your computer, or put your current GPU in another computer and see if the problems remain.

I'm not an expert, but maybe you should also check if there's everything alright with your monitor?
Since the screenshot looks normal, GPU seems to have no problem with generating a proper image.

This sounds more like a monitor problem to me.

What were your GPU temps like when it was fucking up? Could be a cooling issue if which case you might get lucky and be able to salvage it... or unlucky if its taken the PCI-E with it. PSU is possible but tbh they just tend to die completely, if nothing else has power issues it would be fairly unusual. Same goes with monitor problems, if your having no issue with the iGPU I'd look elsewhere first.

Honestly PC problems are a bitch to diagnose without spare parts.

I have a similar thing on my laptop, but restarting it fixes the problem, like nothing happened and it only happens once every 2 months randomly. The trigger seems to be starting a game in full screen in my case. My screenshots also appear normal while this is happening, but this is how it looks like http://prntscr.com/bwiwf0 (low quality phone image). Trying different drivers didn't help. I haven't found a solution yet, but I hope this information helps you.

I wouldn't point my finger to the PSU, it seems very unlikely to me.
If your GPU has another port to connect to monitor, you should try that.
Are you using the same cable with motherboard GPU, or another one ? because it could also come from a faulty cable.
Trying safe mode as suggested can give clues, I'd also try to download latest drivers, uninstall current, and make a fresh install. But I don't think drivers are the most likely cause of the problem.

my friends Radeon 6790 died just like that!

Not an expert, but reading what you wrote sounds a bit like stuff that was happening on PC from around 2008 like two years ago - brother bought new GPU and it all got fixed.

I would suggest it is an overheating gpu. While they can handle much greater temps than cpus (mainly because a visual artefact isn't a deal breaker whereas the equivalent in a cpu is a crash) running them at too high a temperature can cause problems over time.

If you have access to another gpu I would suggest plugging that in for a test run. If this has no problems then it is very likely to be the original gpu is going to die. You could possibly stretch out the lifetime of it by underclocking the card or limiting the frame rate (ie instead of 60 fps doing half vsynch and chopping it off at 30).

I would suggest frame limiting as a better option to begin with and then moving to underclocking if need be.

you can try a few last steps:

• Check if the monitor works correctly with another source
• Use dsplay driver unistaller and do a clean driver install
• Using an overclocking utility increase voltage (+50mv) and stay with factory frequencies on both ram and core, see if it runs ok

sounds like gpu issue to me, what make model is it? did you google for similar issues? and depending on who makes it, it might be warrantied still, my MSi card that recently died, i was about to just order a new card when i said wth and checked the product page where I ordered it, and it has a 3 year manufacturer warranty.

It sounds like a dying GPU, indeed. Or it could be the PSU.
Could you post your hardware? Specifically, the GPU and PSU.

wait, print sscreen was fine?
the problem is connections. either screen, cable or indeed GPU connection damaged.
if you see the picture on scrennshot the gpu is fine - it is making the picture, the screen is not displaying it properly.
got another cable or monitor? can you plug that monitor to a laptop?

isolate the problem before jumping to GPU conlusions

Visual glitches are an indication of your GPU dying from my experience. I'm 99% sure (I would say 100 but you never know) it's your GPU failing from what you've said. It's extremely unlikely that it's your PSU.

Edit: also when your GPU is failing, the longer it's on the worse the visual glitches get, from my experience.

I had a similiar issue once in my old laptop, except it was horizontal. Had to replace the screen of my laptop or something like that to fix it (well i didn't do it, it was the technician that did it but its what he told me).

It could very well be an issue with your monitor, try plugging your pc to a TV see if it still happens. Could also be something isn't properly plugged in your pc, i had an issue not long ago where my computer would crash/freeze often when playing certain games, while some others would be less often to cause the issue. I thought it was faulty drivers, fixed the drivers, the issue seemed to have gone for like a week then it returned. Then i started playing around with the hardware, removing cables and putting them back in, using the trial and error method. Managed to fix the problem by removing the GPU PCIE cables and plugging them back in, one of the two cables plugged into the GPU was causing issues from what i understood.
EDIT: Should also add that i googled alot about this issue, people told me that GPU was most likely dying or was faulty. Also saw alot of people with identical issues, some of them solved the problem one way or another, some people didn't even care and simply just bought out new hardware.

Whatever you do, don't buy a GPU without trying to fix the problem, i was thinking on buying one without giving it a shot because i'm lazy as hell, as you can see i ended up saving money and am still using my good old asus gtx 670. Which has barely been forced to heavy gaming duty that much.

As for the PSU, i'm not sure if its the main problem. It could be... Can't really comment much about that but it's hard to accept the PSU being at fault, unless faulty cables, similiar to what i had. Could also be GPU being faulty.

Try doing some trial and error fixes on your own, Unplug cables related to PSU and GPU and plug them back in, see if things are working better. Remove the GPU from the PCI slot and put it in a new one or simply reattach the GPU to the slot, removing and placing it again. Try dusting off if you haven't already. Try a new display device see if it still happens. Try new HDMI cables. Try new PCIE cables. Try googling for similiar issues with solutions/hints. Try switching the resolution and the VSYNC options for your gpu (alot of the screen tearing in games is caused by these 2 factors, along with a few others, i know your are getting the issue outside of gaming, but might be worth checking it out).

You could just try to just take the gpu out of the case
and then insert it again..

Do you have a spare GPU lying around anywhere? If not, I'd suggest getting a really cheap one for testing purpose, it can be very useful to diagnose problems with your computer's graphics.

It's your GPU.

I had upgraded my PC since 2012 with newer graphics card (Sapphire 6870).
A couple of months ago, the same thing happened to me. If I restarted my system, the image returned back to normal, but after a few minutes the screen refreshed and the image was again cut in half, swapping parts on my screen, just like yours.
Completely removing and reinstalling drivers didn't work.

Replacing it and putting my old graphics card back (ASUS EAH3870), I had no more problems.

I still haven't checked what's wrong with the faulty card, in case it needs some simple maintenance or any possible part replacement...

Maybe you could try to upgrade all drivers on your system. Ever tried "IObit Driver Booster"? Helped me with some strange problems, but I am not sure if it can help you.

Almost definitely not a PSU issue,

Almost definitely a GPU issue (especially now that you're using the mobo GPU, and it's working fine). If you're not sure, you could go to some computer service and ask them if they can try plugging another GPU in to check if it works with that also. If yes, then.,. yep, your GPU is dead.

EDIT: Also, might wanna try cleaning inside the computer and checking if all the cables are in order (especially those connected to the GPU)

Assuming that you are using the same video connection to the igpu as you were to the Radeon 6870 and it is working fine I would say that eliminates a cabling issue unless its the connector itself. Secondly, If you have the same problem after rebooting the computer I would say that its most likely not the power supply as the 6870 shouldn't be under full load. This leaves either over heating, driver or hardware failure as the cause. If you try and use the 6870 again after using the igpu for a while does it occur again immediately? If not, you can try and open the case and blow out the gpu fan on the 6870 and then download Furmark (which will put the gpu under full load) and watch the gpu temperature closely to see if it occurs at or around a certain temperature.

Disclaimer: If you use furmark and your computer spontaneously combusts its not my fault.

If the on-board GPU works fine, it is almost your dedicate GPU doesn't work normally.
Do you also see the same problem when you boost to BIOS?
If so, it is also unlikely a software driver's problem and I am afraid your dedicate GPU might be dead.
