My 7870 is about a month old, just over the limited warranty of the store I bought it from. About two weeks ago, the black screen

loud buzzing noise happened. This happened while playing League of Legends, and recently it has started happening more

frequently. The card is only about 40 degrees while playing, so I can't imagine that it is a temperature issue.


My problem is the same as the one in this video:

Hmmm, this is actually a very weird problem. And it looks like, in the comments of the video you posted, that many people have this problem too... I will look through it and update you whenever I can :)

I had the exact same problem. I had the Sapphire 7870 OC and at any random point, my screen would go black and not respond to anything with an annoying sound loop. Turns out it was poor-quality capacitors that AMD used for testing. They realized they sucked, but didn't get the word out in time, so several manufacturers have this problem. It's impossible to fix, but on the good side a lot of manufacturers have been very lenient on the warranties and returns since the discovery of the problem.

I was lucky and managed to get it back to Newegg within just a couple of weeks. Now I have a gtx 670 ftw and couldn't be happier :)  So basically, you'll have to RMA the card. It's a hardware problem that can't be fixed :/
