AMD Sapphire Radeon 7850 Artifacts and black screen after boot

[Thatchubyguy]

A few days ago, I attempted to play DOTA with a friend. I had played before so I expected no trouble. However, when the game finished loading, my screen went gray with yellow vertical lines across it. I could still hear the game sounds and my friend's voice. I panicked and restarted the computer. It booted up fine but when it reached the welcome/login screen, there were horizontal black lines with rainbow pixels mixed in here and there every few inches down the screen. After login and loading of a few things, the screen went completely black. I asked a couple friends for help and took their advice, since I'm not as tech savvy as they are, and I ended up reinstalling my drivers through AMD, but the problem persisted. I used DDU to completely clean out the drivers and rebooted with the normal intel graphics 4000 adapter as well (the computer functions perfectly fine with the intel graphics, but isnt able to run certain games), then reinstalled the drivers but still had no luck. I also went into to BIOS and changed the IGP settings as recommended on another forum but that didn't help either. Eventually, after a lot of tinkering with catalyst install manager, I realized I can install all the drivers and have no issues except for the AMD display driver, which has an option to be turned off. I tried the beta version and an older version of the drivers as well but they both caused the same issue. I don't know if i can play games without that specific driver, as every time I try to run League of Legends, there is a DirectX compatibility issue. I have been looking through forums for days with no problem specifically like this and I would appreciate any help I can get to fix the drivers or just go without them while still able to play games and do other tasks.

I believe hat your card has been "broken". Try using it in another system and see if it wil do the same.

I don't have any way to check it in another system. Is there anything else I can do?

 

[CreationP]

Unfortunatelly no. The fact that the on board works as expected but GPU is not states that the monitor is ok, the cables are ok, your pc is ok but the GPU is broken. Although this is the reason there is 1% chance to be something else. And that can be found by testing the GPU in another system.

One thing I can tell you, its a long shot but what the hell, is to remove all your drives except your OS drive and try again. Maybe the PSU does not give enough voltage to the card. But that is almost less than 1% possibility.

Best way to test problems on PC is trial and error.

Well it didn't work and I dont think it's the PSU since its been working with that PSU for so long. Thanks anyway. If there are any other suggestions I'll take any I can get

It may be dead on arrival so try and RMA it.

 

[Thatchubyguy]

I had the card for over a year already and it worked really well so I'm pretty sure that wasn't the issue. Sorry for not saying before.

Electronic products have 2 years warranty. Your's is on warranty. Try to RMA it or get it fixed by an official support site.
