Hey guys,

This has been an ongoing issue for me and because it only happens every now and then I've been able to put up with it. Basically what happens is I'll either be watching a video/playing a game or browsing the web and all of a sudden my graphics will start to play up. I get these 'blue squiggly lines' that show up (especially in videos) & also funny colors appearing on parts of my screen (different colors/missing textures) and nine times out of ten my screen will go black and then I'll be treated to a message saying "driver x has stopped responding and has been restarted, etc." Please note, that message and my screen going black doesn't always happen - sometimes it just seems to correct itself.

All my searching has lead me to believe it could be one of the following:

1) Driver issue.

The reason I don't think it's a driver issue is because I've clean installed every driver known to man and had the issue repeat itself on all of them. I've tried the drivers that came with the card (ASUS drivers) as well as the latest drivers supplied on the ASUS website. I've tried the latest WHQL drivers on the nVidia website as well as the latest beta drivers (295.51 at the time of post.)

2) Defective Card (please don't let it be this)

Not really sure how to test this one. I ran the furmark program which my card "survived" and got up to about 70 degrees which I think is about normal for a GTX 560 when under stress. Any other suggestions for testing my card out? I've also cleaned it out thoroughly and verified that the fan is in good working condition.

I'm trying to find a screenshot someone else has taken with the same issue so I can give you guys a better understanding of what's actually happening but until then you'll just have to use your imagination. 'Blue squiggly lines' is the best way I can describe it, like missing textures or something, very prevalent in videos but also popping up in three different types of web browser as well as some games.

My specs:

Intel Core i5-2500 CPU 3.30GHZ Quad Core
8GB RAM
ASUS GTX 560 Graphics Card
Windows 7 64bit
CoolerMaster RS 460 PSU (ATX 12v) (Should this be upgraded for my machine?)

I've tried to include as much information as possible. I did build this computer on my own but I'm still learning and am in no way an expert when it comes to hardware so please let me know if I've left anything out.

Thanks!

From what I understand, you need at least a 500w PSU for this particular graphics card.

I'm dealing with a crapload of problems from my GTX 560 Ti at the moment as well, although my problem is somewhat different (and more severe, I believe) than yours.

I would upgrade the PSU to at least a quality 620w. I can't guarantee that that's the issue, but I would do it anyways.

I know the current Nvidia 500 series drivers have been very unstable. From what I've read, 275 has been the best driver.
 
Hello.
I never had a problem with any WHQL drivers from nVidia and its probably unlike to zero chances to have a driver issue with a driver being out there for more than 3 months.
But, your PSU might not have enough power for your system. Although its a great psu, its not recommanded for mid-high systems. With almost 80% efficiency isnt enough for a 460watt psu. You might need a better one maybe a corsair c500 or 600 depends on how many hdds/optical drives you have etc etc.
There is also a little chance that your card might be defective, but since your power supply is probably not enough, its very hard to see this on your system.
You can try the card to a friends system to test it :)

Thanks for the responses,

Can any of you suggest a PSU replacement? I do a lot of gaming and currently have 2 hard drives installed (300gb main / 2tb storage) if that helps with deciding.
