Is my GPU dying ?

Classic errors when the GPU still works but has soldering connector-errors which might also cause random crashes/freezes -
first thing to try is plugin the monitor to another hdmi/dvi connector and restart the computer if there's less or no errors.
If its the better, worse or just a black screen that's additional confirmation ... that the soldering tin is loose.

Assuming your cables are fine (wouldn't doubt) and chips/mem/transistors too, warranty gone - you could try baking your GPU,
which sounds crazier than it is. Have done that years ago with my own and the GPU's of a friend worked 2 out 3 times ...

The soldering tin on the GPU board around the chips/transistors/memory gets loose due to temperature changes of usage.
What helps reseating/re-flowing the soldering tin. If you're lucky as there are various tins used for it which might not "reflow"
by baking the GPU (require higher temps which are more likely to damage something) - i kid you you not, it works afterwards up to a year.

What to do?

1. have some thermal paste
2. unmount the heat-sink-fan from your GPU (wipe off the old thermal paste and dust)
   and all plastic parts you're able to remove easily (DVI plugins will be fine)
3. pre-heat up your oven to 195° - 200°C
4. put some aluminum foil balls under it, so the board doesn't touch directly touch
5. wrap some baking paper around it in case it goes bad (smell/whatnot)
6. put it inside the oven with the fan side up
7. don't close the oven door at once wait 1 - 2 min then close it and wait for max 5 - 7 minutes > time to get it out
8. switch off open it carefully put out the GPU without touching it on the sensitive stuff ... wait 15-20 min to cool off
9. and its most probably good as "new" unless the transistors/chips took damage which is possible (~ they easily withstand 120°C) but unlikely for the time-span and temperature and should last several months up to a year or longer ...

^ there are for sure better tutorials for it on the web ...

well? got anything new to "report"?

since 2011

honestly i am surprised it lasted this long. extremely low chance its not the gpu or least of all the solder points on the port you used.. and i dont say that with any dislike in brand or type, thats just about the life expectancy of all GPU cards really.

congrats, welcome to the no-gpu team. mine died 2 weeks ago and i'm working with an ati 3200 that can't run a single game. might aswell delete my account from here since it's useless.

my GPU died 2 weeks ago as well. Running on Intel right now. RIP laptop ;-;
where is my new computer.

The iGPU is noisier because it heats the CPU as well, causing the cooler's fan(s) to spin at higher speeds.

I'd say those glitches are almost certainly a graphics card issue, possibly a defective VRAM chip. The OCCT suite has a graphics memory test module, you could run that and check for errors.

Same as my nvidia GPU... died with some artifacts 2-3 month ago (week or two after warranty expired and that day nvidia released bad driver).
Don't know is it coincident or drivers killed my gpu...
I tried other graphic cards and they worked. After that removed gpu and installed MB card and everything worked fine.
I become pro in heart and solitare :) and 30fps cs go master :)

Try different pci slots, re-attech all cables, look at gpu cooler - is it working and install older gpu drivers.
And pray... a lot of pray :P

Too much money for GPU.
I will need few more month to buy new gpu 1060 or RX - whatever i find cheaper.
