GTX 770 distorted audio, low frame rates and freezing screen

Hi Tom and everyone else, I bought a pair of 770s two years ago, one out of warranty and one in and found that over the past few months, GPU 1 has been going through a few issues. It started with a huge drop in frame rates while playing a certain game along with static audio and then a completely freeze. It wasn't the same with every game I played, but others were definitely worse. It got so bad at one point that I couldn't even boot into windows. It somehow fixed itself and then every now and then seemed to go through a few sound issues. After doing a bit of tinkering, I realised that it was only happening with GPU 1 and when I set my display to only go through GPU 2, everything was running fine. The sound was clear, games ran well and the system in general didn't feel so sluggy, so I yesterday removed GPU 1 and feel so much relief (as does it seem my PC), and while I'm lucky enough that the card in question still has 2 months warranty on it (The other is now sadly 7 days out of warranty, though it shouldn't be such an issue) so I will be doing an RMA with my supplier (assuming they don't mess me about, I get a little scared of that), but I'd like to know if anyone has any idea what is causing this?

From what I've monitored, when I've been able to, the card would usually be somewhat cool (around 60 degrees), but the power usage reach 100%, at one point, something related to power even reached the number limit. I figure heat was never the issue as I never felt safe letting the card reach above 85 degrees, so it would always throttle when it hit that target.

If you're curious about warranty information, It's an MSI GTX 770 2GB and I'm in the UK.

Thank you.

TL;DR - GPU 1 in GTX 770 build suffering distorted audio, low frame rates, freezes and on occasion BSOD. GPU 2 has never had these issues.


EDIT: I should also note, that BSOD on one occasion was occurring extremely slow and yesterday, instead of a BSOD, the screen glitched and while the wallpaper was showing, blue pixelated squares appeared in a consistent pattern across the screen.

  1. Sounds to me like your GPU decided to die. I highly doubt that it's anything else. You could see if MSI will accept the RMA even though it's a few days past.. No harm in trying

    Oops, sorry, I meant the faulty card still has 2 months of warranty. I just phoned up the place of purchase who put me through the MSI because the fault happened 6 months after I purchased it, but they just had an automated woman give me an email address! >.< Strangely, MSI claims I'm in charge of logistic charges because the supplier only decided to honour warranty for one year (which is different to what she said at the shop). Bit upsetting that I still have to pay for warranty. I might try to kick up a fuss later on if I'm not satisfied with the result. Luckily however, they stated the warranty is actually for three years and not the two years I thought it was.

    I think it would be nice to keep updating this post as an experience thread, I know others have liked to do this and it's great for any new buyers.

    Ugghhh!! It's not been a great ordeal. I had made a mistake as to which store the GPU came from, which ended up being the one just over 2 years old. They almost weren't going to take it, but because I mentioned MSI's three year policy, they said I can RMA it. Inconveniently, however, upon inspection, they told me that my warranty has been rejected due to "physical damage" as it had no serial number on the card. This stirred me up a little bit as I'm certain it's one of those lucky few individuals which isn't labelled by a number. I did mention that I never saw the sticker on it so they're sending it back to MSI with no guarantee of repair or replacement due to the lack of sticker. I will just live in hope, I think!!
