nvlddmkm hell

[pim16aap2]

Hello,

 

A few months ago, I bought Gigabyte's GTX 780 Ti GHz Edition (GV-N78TGHz).

When I finished my build, I tried to play a few games. BF4 and AC IV. 

Within 30 minutes, the game would crash. In the event viewer I could see that nvlddmkm has crashed and successfully recovered.

 

After spending hours and hours trying every fix I could find on Google, I decided to just send it back to the store.

After some testing, they found the exact same problems I had been facing and passed it on to Gigabyte.

 

A month later, I finally got it back. When I tried to launch to play those games again, they still crashed. I tried a clean install of Windows on a separate SSD with default settings on my motherboard, but they still crashed. I just sent it back for a second RMA as I couldn't think of anything else I could do.

 

At the store, they tested the game again, but this time it didn't crash at the store. They did find 5 "misrendered frames" after running OCCT for a while though, so they sent it back to Gigabyte again. I asked them what else they tested and they tested it with the following programs: OCCT, BF4, Furmark and Heaven3D.

 

While the GPU was gone, I also ran a few tests on my RAM, as I heard from a few places that that could be the problem. I tried running Memtest64 and Windows' own RAM test. Memtest64 didn't return any error and I cannot find Window's RAM test's results, but I assumed that Memtest64 should be fine.

 

I got it back yesterday and I immediately put it back into my pc of course, eager to try it out again. I launched Watch Dogs, but within 5 minutes it crashed (same error again! gotta love that one). I tried to launch it again, but it crashed even sooner than before. I tried playing AC: Liberation and BF4 as well, but this time I recorded the GPU's stats with Gigabyte's OC GURU II. Here are the results:

 

Assassin's Creed: Liberation:

 

 

Battlefield 4:

 

What I had noticed was that the power consumption drops to +/- 41%, a few seconds before everything else starts dropping, does that indicate anything at all?

 

I am going to try to put it in someone else's computer soon, but should I maybe try to RMA my PSU if that doesn't work either? Or maybe just send in half the computer at once? Ram, motherboard, PSU and maybe the GPU to continue my game of pingpong with it? I would very much like to get it working now. It has even dropped to 2/3 of its original price and I still haven't been able to play something demanding for more than 30 minutes (played so many parts of the AC4 campaign so many times).

 

 

 

EDIT: Sorry, forgot to include my PC specs:

CPU: I7 4770k

Motherboard: Asus ROG Maximus VII Hero

GPU: Gigabyte GTX 780 Ti GHz edition

RAM: G.Skill TridentX F3-2133C9D

PSU: Corsair AX860

SSD1: Samsung 840 EVO (250GB)

SSD2: Samsung 840 EVO (250GB)

HDD1: Seagate Barracuda (3TB)

HDD2: Some old 1tb drive (can't remember which one it is tbh).

It would help if we knew all your pc specs. But it does seem possible there isn't enough power for the gpu. Give us all your specs then we can go from there.

It looks like your power consumption is inconsistent so it is likely your psu rail for the gpu is bad. According to my gpu chart, the graph for power consumption should be similar to a digital waveform graph

Sorry, forgot to do that, added it to the post.

So I should try to send my PSU back? it should supply 860Watt, so I thought that it should've been fine, even if it delivered a bit less than that.

If you have the option of putting your gpu into another machine, try that first. Else, you will have to wait weeks before it comes back.

Yeah, I would, but I don't really have a chance of doing that. I doubt that the friend whose pc I'm going to try to put my GPU in (once he tells me a bit more about his pc) will enjoy it if I take his pretty much apart. I can live without my computer for a while though. I still have my laptop and I am so... damn... busy... (just started at university).

One thing I did with my bad gpu is send it in for replacement and purchase a different one from a local store. Once the gpu arrives, I sell it off online on amazon. At least, that will save your time from not using your pc

Yeah, If I really needed/wanted it, I'd probably buy it anew and then return it just before the 2 week period ends
