Upgraded to GTX760, now crashes to black screen

Joseph S · Dec 9, 2014

I've been a lurker here for a little while, and just wanted to say there are some great posts on this place. Lots of useful information.

I'd like some help with a recent problem I'm experiencing.

I've been looking to upgrade my computer, so I can have a more capable machine for gaming and rendering. The machine I originally bought was this one:

ASUS CM6730
Intel Quad Core i5 (3.0 ghz)
8GB DDR3
Zoatec Geforce (2 gig) small graphics card

I upgraded the power supply to a 500 watt unit, shortly thereafter, installed an extra 1TB Western Digital hard drive, and installed a wireless network card. I've had this setup for roughly 1.5 years.

A few days ago I bought a new graphics card. An EVGA Geforce gtx 760. It installed fine (there was enough room thankfully), installed drivers etc. I load up a game (in this case it was Warframe and DOTA 2), and it worked for about 3 minutes. Then it hard crashes to a black screen, and my tv says "No Signal". I repaired Windows, repeated the process, same outcome. I tried hooking up different pin combinations, same outcome.

So I went into BIOS settings, and saw the voltage was changing. The meters were going into red at times, so I thought...replace the power supply. I was only using the bare minimum, so it wouldn't hurt. I bought a Corsair CS750M, in case I want to add more things for a later date and ensure I have enough power. Install that, it loads up fine, I launch a game, and it crashes again. The only hint I've gotten before the black screen, is I experience a short freeze, some strange banding appears, the colours are distorted where the banding occurs, then crash. This happens in about 2 seconds.

So now I'm stuck. I've run out of options as to what could be causing the problem. It's not the power supply anymore, and while the case is cramped, I'm testing this with the sides open to ensure enough heat is escaping. The CPU temp in the BIOS was reading 44-47 degrees idle, not under load. The card remains cool.

Anybody have any ideas what's causing this? Aside from a faulty card, I can think of only 2 things. CPU is overheating now, or the motherboard is not compatible with this card. But how/why would this even be possible?

In case anybody wants to see the rig, here are a couple of pictures:

PS - The cords are not touching the fan. There's a few inches of space between the cords and the fan.

When you run the game could you open a monitoring service like open hardware monitor? Also did you buy the card new?

it sounds like a faulty card more than anything, plug in your old card if you still have it and see if it still works fine, if it does its the GPU.

I haven't tried a monitoring service yet. I'll give that a shot tonight. Will it save a log before it crashes though? I bought the card new.

I will try that tonight as well, I kept the old card. One thing about this though. If the old card still works, how will that tell me the new GPU is the issue, and not a compatibility issue? I really hope you're right though. Exchanging would be so much easier then searching for a new motherboard...then a new case...

I'm exchanging the card nonetheless, just to make sure. There's no way I could pick 2 broken GPU's off the rack :heink:

Joseph S :

I checked and the 760 should be compatible with your motherboard, I doubt it would have fit if not, and it certainly should be.
I would recommend trying the old card and if that works then contacting Nvidia support and get them to help you, since if your old card works its 90% your 760 that is broken.

That's a good idea, and very reassuring. I had budgeted out around 500 for upgrades, so if I had to buy a new motherboard, or CPU, a new case etc. then that would really suck.

I'll post back later with the replaced card. Hopefully somebody else who's having the same issue can read this and fix their problems as well.

Well and on the compatibility, i wouldnt think it would boot either

Update:

So I replaced the card with my old Zotec, and it booted up fine, ran the games, no crashes. Then I took the card back to where I bought it, and was going to leave my machine there for them to run diagnostics, since they didn't have any GTX 760's 4GB left in the store for me to replace.

After talking with the tech guy, bringing in my machine, I ended up talking to another one of the techs there, and he told me they still had an MSI GTX 970 4GB, on a black friday special, for about 50 bucks more then what I paid before. So I just bought that and returned the old card.

Now it boots up fine, zero problems whatsoever. The card is fantastic.

As to what the problem was, I don't think the fans on the 760 were working properly, and was overheating. Hearing the 970 under load, plus the CPU fan...the thing is loud, and it gets pretty warm even with the case off (CPU mostly). So I'm sure it was overheating because the card was malfunctioning. The other card, you couldn't even tell it was on. It made less noise then my old, small Zotec.

In closing, the card was most likely broken. So to anybody who's having a similar issue, where you hard crash to a black screen, tv says "no input", you experience banding before the crash, it's possible it's a defective card and it's overheating. My TV had a similar issue, same banding patterns, distorted colours etc. and the repair guy said it's overheating.

Thanks again to the people who responded.

Congrats on the new card! Enjoy!
