Hello,

Firstly I'm sorry if this is the wrong section wasn't sure where to post this and I'm very desperate.

I'll try my best to explain the problem as clearly as possible.


I've owned the EVGA GTX 980Ti for about 2 years now. Throughout these 2 years I have always looked away from overclocking only until recently (48 hours ago).

After watching videos and reading tutorials for about an entire day I was actually looking forward to giving it a go purely for that extra perfomancer for the money I spent on my rig.

I downloaded afterburner and I then proceeded to put +10 on the core clock and done a whole playthrough of a benchmark. I kept repeating this all the way up until around +120 core clock, this was when my PC just shut down and would not turn on at all. I press the power button on my tower and I heard a click but nothing whatsoever.

After about an hour of sobbing and getting stressed thinking I destroyed my entire PC I managed to find the culprit of why the PC wouldn't start. If I unplugged the GPU from the PSU my PC would boot. Soo nas I plugged the coord back into the PSU the problem was back, I could not start my PC.

Luckily I have a very very old GPU. The GTX 750Ti. I put that into my PC and it booted up fine.


My question is how do I know if it's the PSU which has failed or the GPU? I mean my old 750Ti doesn't reqiure much power so the PSU isn't exactly under-load to test it, right?
I'm very sad and fustrated. I'm reading threads on other forums and people are saying the GPU is dead or the PSU is dead. How can I find out the real problem here?


List of this I tested;

- Removed the circular battery on my mobo and reinserted it
- Booted Windows 10 in safe mode and used DDU tool to remove Afterburner along with any saved profiles (also removed GPU driver)
- Used the tool which came with my PSU and the fan seemed to spin when I press eco mode (people say this is not a good test to know if the PSU is faulty)


Any help is appreciated. Very depressed about this.

First of all don't panic and make any rash decisions.

From what you have described I assume you were overclocking your gpu?

It's possible, if there is no sign of life that you have killed your PSU ( power supply unit).

What is the spec of your current machine?

What happens when you hit the power switch?

yes i was overclcoking my gpu. here is a picture of my specs: https://gyazo.com/b414bde2775a4591a4e1178ed9ffde96
PSU: EVGA Supernova 850

when i hit the power button sometimes i here a click by the psu cable
 
Have you tried resetting the BIOS on your motherboard and then trying again? Have you tried booting using the onboard GPU if your CPU has one that is.
 
Were you overvolting your gpu or just increasing the core speed.

Where did you get your card from? I only ask as that screenshot says it's only got 2gb or vram and it should read 6gb.

Could simply be a bug in the software but the 980ti has been around a while now I would have thought it would have been fixed

speccy reads my gpu wrpng for some reason. i was just increasing the core speed in 10s.
 
A click when you hit the power button but no power up sounds a lot like it's tripping the over current protection in the PSU. More so if it boots without the GPU in.

That's exactly what happened to my system when my GTX 780 died (VRM failure) a few years back.

Does the GPU look and smell fine when you physically inspect it?

yes. however last night which i can vaguely remember due to spending hours at 3am trying to fix the problem i did smell a burning smell for a second of two. i put my face near the motherboard to try and find where the smell came from but i couldn't find it. not sure where it came from, could it maybe be the gpu? it was just a quick burning scent.
 
Sounds very much like a dead GPU. No boot while plugged in, trips the PSU protection. You could take the GPU apart to see if there's a burnt spot but ultimately it'll be something you can't fix at home (unless you're handy with SMD soldering).

I'm so sad by this. For 2 years I always held myself back to not overclock due to knowing a problem like this could happen. I was always a afraid. Last night I watched a video about getting the most out of your rig and I attempted to overclock the most slowest and safest way possible and it turns out I destroyed my entire GPU?

How does this happen. All I did was increase the core clock by +10 after every successful benchmark test I managed to get +110 and now my GPU is dead? This makes me so depressed. I have no money to replace any parts and now I don't have a working 980Ti. I do have 200 days left on my warranty (thank god) but it makes me more depressed having to go through the whole process of sending the GPU back through the post which will cost me a fortune for postage.

I won't take apart the GPU because I think that ruins my warranty.
 
I'm pretty sure EVGA are ok with disassembly, and will still honour your warranty. They have some of the best policies, but it's still worth checking.

I wouldn't say that overclocking directly killed your GPU. It could be age-related or you could have stressed it too much over time. But this is the inherent risk of overclocking, that you are running something outside its rated specification. It's lucky that manufacturers accept overclocking inside their warranty policy, a car manufacturer probably wouldn't repair a car that had been overpowered and broke its transmission.

I don't know if you are responsible for postage one or both ways, but it shouldn't be too much considering you'll get a replacement graphics card out of it :)

thanks for the response. i would be much happier knowing the culprit is the gpu and not the mobo or psu etc. are there tests i can do to confirm its the gpu?
would suck if i would through all the effort to get a replacement gpu but it turns out it was something else.
 
I think if taking the card out makes the PC boot again that's a positive sign. Another possibility is that the PSU can't handle high current or the PCIe power cables are damaged, but unlikely. You'd probably see issues under load rather than no boot at all.

If you're very worried, you could try another graphics card in the slot. Or try other power cables as the PSU has more?

i put my very old 750ti in this pc and it works fine :c
 
what software were you using for your gpu overclock? cos i wondered if deleting that off your hard drive would help as would make the pc not start with the high voltage going to the gpu

Pretty sure that high voltage only kicks in under Windows when the gpu is under load, don't think it supplies it on startup, although happy to be corrected on that.
