Odd Black Screen Crashes? Kinda freaking out. PSU or GPU causing it?

Had this issue happen twice so far.

While gaming 2 different times on not very demanding games Torchlight 2 and DotA2, just randomly my computer screen will black screen crash and my GPU fan will spin to what sounds like 100%. The first crash the computer restarted itself after 15ish seconds. The 2nd occurrence, I had to manually restart it.

I've contacted both EVGA and my Power Supply company and troubleshot the issue...

After the 1st occurrence and talking with a EVGA rep.

1. We've tried clean driver sweeps and installs for my GPU.
2. Clean sweeps and reinstalls of Precision, HWMonitor, Speedfan.
3. Checking my PSU +12v, which is what the EVGA people think is the issue.

In the BIOS, it ranges from 11.69 to 11.93 depending on when I look, it will fluctuate while in BIOS as well. When it says 11.93 that generally stays stable, when it shows lower it will jump around. When I told the EVGA people this they said that this was what they believed to be the issue. Although in an email they sent, they also stated that this range was "acceptable", but the person I talked to said this was actually "unacceptable".

Although they didn't ask for it, this is what my Speedfan "usually" shows me, take into account this isn't under any load other than having a random twitch.tv stream open.




Again this isn't under any sort of load other than twitch.tv stream with basic hardware acceleration under the flash options, basically at most 5% according to Precision. I also know that no software/bios reading will be 100% accurate compared to an MM which I don't currently have to test the PSU.

When it is under load the reading spike even lower, but never above 12. But the spikes are quit dramatic. No clue how to infer much from this, besides putting together a computer and basic troubleshooting, this is a little past what I'm comfortable addressing by myself.

Anyhoo, before contacting my PSU company, I first tried all their troubleshooting. And a day later, randomly I got another black screen crash and GPU fan spinning to 100% that this time required a manual restart. Right before that happened Speedfan showed my +12v dip near 11.4-11.5 under load.

After that I contacted my PSU company, and talked to the guy who RMA'd my first 2 units which were defective. At first he seemed skeptical that PSU could cause a black screen crash making my GPU fan spin to 100%. But when I gave him my +12v readings he agreed that seemed off, and the fluctuation seemed off.

So in conclusion, he's sending me a replacement, this would be #5 including returns to the retail store during first 30 warranty because of spotty fan issues.

Anyhoo my question is... Does this seem like it actually is the problem. Or does this sound like a GPU issue?

I'm skeptical because while no one was certain they seemed to want to defer the problem. The PSU people wanted to say it was the GPU, the GPU people were adamant it was the PSU.

Since the PSU people seemed to think that whatever +12v readings I'm getting can't make the GPU fan spin 100% or whatever.

Here's my specs, everything is stock settings... I built this rig 10months ago and have no issues other than random PSU fan issues, this current PSU has seemed to work fine for 7months.

i5-3570k
EVGA GeForce GTX 670FTW
Crucial 256gb SSD
AsRock Z77 Extreme4
Crucial 2x4gb @1600 RAM
Thermaltake 750w Modular Smart Series 80+B PSU
Windows 7 Home Premium 64bit

Any help would be greatly appreciated :)  If anyone could offer any sort of a reassurance that I'm on the correct path, and/or any information of what actually could be the cause if this isn't. I've pretty much tried everything that anyone has said, granted this has only happened twice, I won't try any game that puts the GPU/PSU under load until the new PSU comes, for fear of well, I don't know but not everything is still under warranty.

Again, thanks for your help.

If the PSU is unstable enough to cause the GPU to crash then yes the GPU fan could spin to 100%. But I am not sure if the difference in the +12 readings you are getting is enough to cause that. What driver version are you using with your GTX 670?

Currently 314.22. Through a clean install. Prior to that I had also been using 314.22 with no problems since March 26th, roughly 3ish weeks until that first crash occurred.

The whole computer crashed actually. First error message I got Windows said BSOD in the Event Viewer after it restarted itself about 15seconds after the blackscreen/fan increase, the 2nd one, I don't know since I had to manually reboot because it wouldn't restart itself like the first time.

Right now while just browsing the internet searching for someone with a similar issue, Speedfan is showing my +12v spiking around 11.6, and that's under no GPU load.

When it did crash those 2 times it was under "marginal" GPU load from DotA2 and TL2(which actually doesn't put much on the GPU, mostly CPU). I haven't fired up any game since the 2nd crash out of fear I'll get another one when the computer needs more power.

Little bit of a follow up... Had the computer running playing some stupid .swf game since I'm staying away from putting the GPU/PSU under much load.

While running Speedfan during that time roughly 4 hours, I noticed that the voltage was progressively getting lower and lower. First hour or so it would fluctuate between 12.0 and 11.7, next hour 11.9 and 11.6, next hour 11.8 and 11.5, til finally it was fluctuating between 11.7-11.4 at that point I restarted the computer and checked the BIOS which showed me 11.2-11.4 fluctuations.

I then Shut Down it and waited 15 minutes and started it back up and the BIOS then showed me 11.9... Speedfan showing me fluctuations between 11.9-11.8 during the first 30minutes and then it started that trend downwards again.

I'm assuming, and again this is just going off common sense and logic, with no indepth PSU/CPU/GPU knowledge... That maybe when my game blackscreen crashed, it was when it was approaching these voltages and if I hadn't shut down it, eventually it would have happened a 3rd time?

I don't know... It's gonna be 3-4 days before the new PSU comes. Am I risking anything keeping this computer on? And again does this seem to relate to my issue? Or is this not related at all?

That psu voltage does seem odd, but the fan spinning to 100% sounds exactly like what my gpu does if I OC it too far. I didn't notice anything about overclocking in your posts so is it at stock right now?

Ya everything's stock.

Little update to this thread.

About 3 hours in with the new PSU, haven't had a crash yet, granted I haven't tried a game in that time, but have watched a few streams for an hour.

I did run the OCCT memtest that crashed once, and made it through that, but that's just 1 short test.

Also notice the difference in +12v on this PSU compared to the first one, which is encouraging.

RMA'D PSU



NEW PSU




So... Don't want to jump the gun here, but it's looking "promising". Hopefully I was wrong with it being a GPU issue.

Although I am using the 310.70 drivers now instead of the 314.22. And I'm using the bare minimum of driver installs, just the Graphics Driver and Physx, I didn't install the HDAudio/3D crap/Nvidia Update/etc.

So really hoping my issue is resolved, but not gonna declare it fixed after only a few hours.

I'll update this, if I end up getting another 0x000000116 BSOD... Which then would mean logically the only thing left would be the GPU.

Thanks for everyone's help.
