Card seems to be damaged it sounds, that's the way it sounds anyway.
I think Hycolours may be defective, not the OPs though.
I did as you said and it worked fine for a few days, but the old problem has now returned
Even with the 13.4 driver? I guess you have a defective card my friend. I would RMA it if I were you .
Do what now?
You tried the 13.4 driver right? Or the 12.10 version?
I meant the RMA thing, I uninstalled my drivers and installed the 13.4 one (not beta)
What brand is the 7850 you have? Powercolor? XFX? Etc. Also, where did you purchase it from and how long ago?
It's from Saphire, and I got it in Mid december 2012 from Amazon
I would get in touch with Sapphire. The card has a 2 year warranty. Ask for a new card, dont send it for repair if you dont have to.
Are there not any graphics tests I can run to check if it's hardware or not?
Because it did work flawlessly for a few days when I uninstalled and installed the drivers
Sure! Run FurMark for a few hours and see if your problem occurs.
Within another 5 minutes it had been replaced with a display of white and purple stripes. But not the same problem as usual, and it was being stressed a LOT more than my games do.
A monitor isnt stressed, it is the GPU. Is this what is occurring?:
Or does it seem more like color distortion?
I'm aware my monitor isn't being stressed, I'm not a *******.
Here is a photo of what I meant
I had the same problem but I found out how to fix it after a while.
It all started when I got the Asus HD7850 V2, I was playing Hitman Absolution maxed out when the screen flashed and got all distorted (The grey image someone posted) the temp reached 71c. Happens that these cards have a high temperature by nature mine idle gets around 32c/33c and playing games with maxed out settings really insane temps and I have a corsair H60 liquid cooling plus 2 cooler master jetflo at 1600 rpm on the lateral, so it's not my cooling system at all. Tho there is a simple way of preventing this...by creating profiles on asus GPU tweaks.
This is what you should do...
Install Asus GPU Tweaks
Create 2 profiles
1 should have the default values
The other one must have the default values except the fan that should be at 100% (this one is for gaming)
Go into settings and activate the hotkeys option.
From now on, everytime you feel like you want to play you need to activate the profile with the 100% fan setting, in my case Ctrl + Alt + 1 is the gaming one Ctrl + Alt +2 the normal one. So basicly switch profiles everytime you want to play so your fan gc doesn't works at 100% all the time.
After this my GC doesn't even reach 60c playing high graphic games even for hours!
