Graphic signal loss AMD Radeon 7870

post #1 of 5
Thread Starter 
Hi, I have an Hd Radeon 7870, with my drivers up to date, and I've been having signal issues since I purchased my PC a year and a half ago.

My problem is the following, at random times my screen freezes for a second, the music stops and the signal is lost, then the screen turns black and then it recovers and a message says that amd software stopped working but it was recover appears on the screen.
Also, after some time playing a game (it doesn't matter wich one) the screen freezes the sound is lost and inmidiately the screen goes black, the PC still works, I can hear it working and if I turn it off and restart everything works fine, but this happens randomly some times is after five minutes of playing some times after an hour... Same as with the sudden losses of video, and is pretty weird because i have an HDMI switcher connected with a console and a TV reciever and this problem doesn't happen with them, well the TV reciever has lost the signal very few times but that isn't related to the PC issue.

Things I've tried:
-Connecting it without the HDMI switcher
-Two different HDMI switchers, one with power supply
-Different cables
-Different drivers (I have updated my drivers a couple of times since I purchased the PC)
-Different HDD ( I have an SSD now)
-Changed the motherboard

I haven't overclocked my system, but I have tried the OCTT test and the signal was completely loss.

I honestly don't have any idea of what I can do now, I've seen a couple of threads with problems like mine, but there is never a definitely solution, so I hope you people can help me.
Thanks.

Firstly. Welcome to OCN! thumb.gif

I can conclude that either your PSU or GPU is faulty.

Post your full computer specs (Such as: GPU, Power Supply, CPU, Motherboard, HDD) For future reference.

I recommend you to use the Rig Builder at the top right of this website to add a RIG to your profile. Make sure you add it to your signature for convinence. This will help others (including me of course) to diagnose issues that you're having.

What temperatures are you reaching on the GPU itself?

I would reccomend trying another power supply to see if that might fix the problem. If not. Try another graphics card.

I'm pretty sure one of these should fix the problem.

Edit: Oh and make sure it's around 450W or more. And that it has at least 30 Amps on the 12+V rail. (Not sure how many amps the GPU requires but thats just to be safe.)

Hi benjamen50 smile.gif here are my specs:

Windows Dir: C:\Windows
DirectX Version: DirectX 11
DX Setup Parameters: Not found
User DPI Setting: Using System DPI
System DPI Setting: 96 DPI (100 percent)

Also my PSU has 500W

Taken directly from dxdiag, if I must post something else let me know.
I will try to write my Rig Builder know (better said, I'll do my best to write it)

Here is a screenshot of OCCT where it shows the temp on my GPU (I haven't experienced the issue today)
temp.png 255k .png file
It's on spanish, if there is something you don't understand tell me and I will translate it.

One thing I would like to know is which method do you recommend me to test the issue? I've been a week at it hasn't happened in that time, but yesterday I had like ten signal drps, and then afetr doing the OCCT test on the GPU the signal was loss completely.
Is it safe to do the OCCT test everytime I want to test the issue?
Thanks again ^^

I checked your picture but I don't think the Graphics Card Temperature is recorded there. I can't find it.

Maybe you should try Unigine Heaven Benchmark. That stress testing program is great for testing graphics cards. I don't think you should be using OCCT.

Do you also have the model number and brand of PSU? E.G Rosewill Capstone 500W.

Ok, I'm downloading Benchmark and the next test for the GPU will be done using it.

My current GPU temp acordingly to SpeedFan is 23ºC but as I've said, I haven't noticed the issue today and I'm not sure about the temp when the issue happens so maybe should I do some kind of track of the system temperature and post a log(?)

MY PSU is Antec VP550P Basiq 550W

Tell me if you need more data, thanks again

EDIT: Also, in other forum they have recommended me to change the voltages of the GPU but I'm kind of afraid to do so.
EDIT 2: Changing the voltages for the core voltage from 1219 to 1300 resulted in a crash after two minutes of starting the test.
Changing it to 1250 resulted in an hour and a half alive and now I'm testing at 1260,which has resulted in an hour and forty minutes alive.
Here are my specs better written than in dxdiag:

-Intel Core i5-3570 3.4Ghz Box
-Motherboard P8Z77-V
-Arctic Cooling Freezer i30 CPU Cooler
-G.Skill Ares DDR3 1600 PC3-12800 8GB 2x4GB CL9
-Seagate Barracuda 7200.14 1TB SATA3
-Samsung 840 EVO 120GB SSD
-Antec VP550P Basiq 550W
-Sapphire Radeon HD 7870 GHz OC Edition 2GB GDDR5
-LG GH24NS90 DVD 24X
-Logitech Desktop MK120
-Cooler Master 120x120mm 1200RPM
