Bought a sapphire R7 260x 2gb(says oc edition but core and memory clocks are lesser than referrence) 25 days back.
Whole system is new.Got a black screen just when sitting on the desktop two days after i built the pc.Restarted pc,everythjing fine for 2 weeks,black screen again,all components running fine inside the cabinet,still black screen tried unplugging and replugging DVi cable,no go,monitor still gets signal after black screen.This was with the the driver which came along with the gpu.
Then installed 13.12 from amd webiste,black screen next day,just when browsing the internet.
Uninstalled that too and installed 13.12c from sapphire which had catalyst version 14.1,worked fine for 8 days,black screen again when watching a movie.Movie sound form the speaker turned into a wird long loop,still monitor was recieving signal.So uninstalled that too and installed 14.3 beta.Restarted the pc and when installiong arkham origins,black screen again,restated the pc and uninstalled that too and installed 13.10.Worked fine for one day and black screen again just after starting the system when browsing thorugh my folders on the hard disk.

Everytime i do a clean uninstall and boot into safe mode and run driver sweeper and only then i install another version.

When gaming this has never happened,No heating issue,max temp is 76 even with crysis 3.To be noted:I live in India,chennai.It is summer now and temps are between 35 and 40c outside.

Even tried leaving the system on for 5 minutes after black screen,display does'nt comeback,all components would still be running.I have to hard shut down and restart everytime this happens.

Even before i bought this card i knew many are facing this issue,with all manufacturers like asus,xfx,sapphire and all.Stll took a risk by going with the card.I just wanna know if it is hardware issue or a driver related problem.If its latter i can wait for a table version.Just wanna make sure it is not a hardware issue,if so i will have to rma this card.

I could not relate each occurance with another,happens completely random.Everytime happened under diferrent scenario_Only thing i could get out of those were like the gpu did not have lot of work to do.Was almost at idle.

Tested drivers:
13.20(worked fine for 2 days black screen,again worked fine for 2 weeks,black screen) which came along with the disc(for some reason this was released before 13.10 or 13.12)
13.10(good for 1 day)
13.12(good for 2 days)
13.12c from sapphire website.(good for 8 days)
14.3 beta(not even for 1 hour).

My whole system config is:
I3-3220
Gigabyte B75m-D3h
Corsair value select 4gb 1600mhz ddr3
Seagate barracuda 1 tb
Sapphire R7 260x 2g Gddr5
Power supply:Corsair VS450(UK version)34A on 12v.

From mtdew332:

"So after two weeks of searching for the cause / solution to my Black Screen issue, I think i've finally nailed it down.
With some help from overclock.net forums.
I'll just quote it here.

(This black screen from power transitions occurs because the memory clock jumps up to full speed (1250, etc), while the GPU voltage (which also controls the IMC--this is the problem) is STILL running at idle volts of 0.9xxx). That idle voltage is too low to handle the IMC, which is controlling the memory running at that speed (this is NOT due to defective memory modules btw), and thus the card black screens.)

The fix, is to increase the GPU voltage, which ALSO increases the idle voltage to the IMC as well. (previous generation cards used separate voltages for idle clocks and 3D). This Is purely a bios/design problem. The IMC should NEVER be running at 0.9xx when the memory jumps to full speed, or, alternatively, there should be 'lesser' memory speed jumps, for when a light load is put on the GPU, so the memory doesn't jump from 150 MHz to 1250, but instead it could be 500 MHz for a very light load (like when the core goes from 300 to 450 MHz), etc.
This is exactly my issue and the solution
.

Symptoms
1: Black screen on cold boot.
2: Random Black Screen while at desktop / browsing web / youtube
3: No Black Screen Issues while gaming.

Solution
1: Upped my core voltage to plus 25mV using MSI AB.
This upped my VDDC to 1.008V at idle and stabilized the Memory controller for those jumps from 300/150 to 450/1250 at the desktop and now no more Black Screens.

I still occasionally see one on cold boot if it happens before Windows and AB loads to set the new voltage.

The Permanent Solution would be a bios with the slightly higher core voltage.
Or a way to edit the bios and set it manually myself
."

"I submitted one and also suggested that the alternate solution posted above of limiting the memory speed to a max of 500mhz instead of 1250mhz in 2D mode may be a better solution.
Since increasing the core voltage also increases heat and will cause the cards performance to drop some since it will throttle more to stay within thermal limits.

Ive actually tried this with a program called GPU tweak from another vendor that allows you to actually set/limit 2D core and mem clocks.
And it works just as well as upping the core voltage a bit.
I set the 2D core and memory at a fixed speed of 450/500....no Black screens.

So limiting the 2D memory clocks to 500mhz would work just as well with no voltage/temp increase or drop in 3D performance

The 260x requires a 500w psu. A 450 is usually good enough, however, the Corsair VS are the absolute worst of the Corsair psu's. Not only do they fail atx standards miserably, they do not come close to output of rated power, are built with multiple substandard parts and can fail spectacularly.
If you are getting "black screens", chances are your psu is to blame. Driver issues usually result in "blue screens"
 
I think you may be misunderstanding me. I'm not denying that it may be a driver. If a previous driver (or a n update) works that's great, it solves the problem.
What I was saying is that your reported problem in general has many possibilities or combinations of issues. Don't assume that it is a driver just because others have reported it. Eliminate possible causes until you are left with the correct cause.

Hey man, I JUST ran into the same problem. So I just installed the drivers on the cd, and waited. For a very
long time. Like it was a 10 minute wait. Then windows suddenly loaded. So try giving it some time.

No don't check gpu boss..that just compares specifications...look for real world benchmarks..750 ti is faster than 650 ti...gtx 750 is almost equivalent to 650 ti and its newer architecture and power efficient..

Use msi afterburner and lock your 2d clock to 750 mhz,while using 3d applications applications it will automatically adjust and use your original memory clock..To lock 2d clock,drag your memory clock to 750 mhz in afterburner and save the profile and go to settings,select profile and select the saved profile for 2d and enable that profile..When using 3d apps it will release clock speed to its maximum..

I think in your case the card is faulty..You should rather contact asus..Because we did not have bsods..

Try using 14.12. There are many methods to fix this issue but let's start with that. Don't forget to use DDU (Display Driver Uninstaller) to remove your old driver. Download your driver from AMD or your manufacturer's website and install.
 
If you read the graphics /monitor threads, you will see that there are similar threads nearly every day. Quite often all it takes is to re-seat the RAM with clean contacts. Other times, the problem is due to an inadequate power supply. Still other times,the GPU driver has become corrupted or a new driver update is incompatible. And sometimes, the graphics card is just beginning to fail.

(Also sometimes just reseating the GPU works too.)

I just pointed one thread for you,but this has been happeneing for too many people with r7 260x and r9 series cards recently with same symptoms.That's the reason i just suspect the gpu and its driver as it is a brand new system.I also understand we can suspect some other component.Also understand it is a probem which can happen with any card and any component,btu why iam suspecting the gpu and driver is because many people are facing the same issue with same card within a short period after its release.

And if you can just check the reviews in newegg with r7 260x cards of any manufactuer you will know what iam saying,almost everyone are happy with the card's performance,but not with the drivers and black screen.I don't think this is one of those common problems,but i will definitely test my memory and re seat it properly and make sure.And i have found one connection with all drivers,with every driver i enabled overdrive but did not change anything there.Could that have been a reason as my card's core and memory are lower than the referrence design?
