    Inside your miiind, and poof.
    I sold my 750 Ti to one guy, it was working perfectly fine before I gave it to him.
    Now the guy says his screen is artifacting, after playing games for about 2 hours. (horizontal lines on screen and such)
    So, is there any way to fix this? What could be the problem? He has a 400W power supply and he doesn't know his other computer parts, could the power supply be the problem? The monitor is working fine btw.

    The GPU RAM could possibly have been affected during handling if anti-static measures weren't followed. This can cause artifacting. If that's the case then there's not really much you can do as it's akin to physical damage.

    It's also worth trying another cable as this can also rarely affect the signal.

    What is the airflow like? Some motherboards I see will put it right down at the bottom of the board and then have the power supply pump its hot air right into it. 2 hours is more than enough time for heat to properly build up.

    Edit. Also what shaunj66 said. I would expect it to show up slightly sooner but if the graphics code is not great then you could hit some dodgy part of the RAM as more and more GPU memory gets used up.

    If its horizontal lines then its either screen tearing or analog to digital interference.
    Artifacting looks the when the things on screen get deformed or weird dots appear on screen or things like that iirc?

    Example

    If its screen tearing then turn on Vsync but i doubt that's the issue.
    Analog to Digital interference is when you use a DVI to VGA adapter or HDMI to VGA adatper, translating analog to digital makes horizontal lines (had the issue with my GPU too so i changed from analog to digital signal).
    If its neither of those then i guess its the PSU. He might use some shitty one and the GPU isn't appreciating or the PSU doesn't have enough juice to run it or it might be some other component that isn't working fine in his PC.

    EDIT: GTX 750 Ti needs minimum a 400W PSU so i guess its the PSU.

    Since it happens only after playing for a while, it sounds to me like a heat issue more than anything else, the guy should make sure there's nothing blocking the fans on the GPU, and tidy up the wiring inside the case to make sure air flows through the case the way it should.
    This is easy to check though, by running SpeedFan or another program that can check GPU temps, and pay attention to the temps a bit while playing and especially when the artifacts start occurring.
    However it could also be an unstable OC if he has OCd it.

    I told him not to touch the graphics card's butt, hopefully he controlled his urges, noted though.

    Yeah, I thought temperatures would be a problem, so I told him to get GPU-Z and check. He'll give me the info tomorrow.

    PSU should be the problem, he was ready to get one, I told him just to check other things first.
    And he is using those DVI to VGA adapters. I also told him that would be the problem, but he said it worked fine on his early card, not entirely sure though.

    He bought an already built PC, so you'd might think it would be cable managed, but if it's this stupid country, then maybe it's not.
    I asked him if he OC'd it, but he said no.

    DVI to VGA will make horizontal lines, that's a fact.

    I got artifacts when playing some games before, and I mean HEAVY artifacting. Turned out that a fan broke and wasn't spinning at all so everything overheated.

    Can. I've used numerous DVI to VGA adapters both at home and at work and myself have never run into that as an issue. Though I don't doubt the possibility of it happening.

    Most of them. (If you know some that work well, and that are sold on ebay, do tell me, because I need one lol)

    I've just used whatever comes with my video cards (usually EVGA), at work I tend to use Monoprice branded ones. It's probably all the same cheap shit though.

    Same here, using the EVGA adapter myself, works fine.

    The one i got the with my MSI card makes the horizontal lines.
