So I have had this graphics card for a while now and it worked fine for about, 7-8 months. This week it started acting up. Under and load, light of heavy, it stopps responding to my monitor after a short period of time, i.e. 15-45 minutes. My first thought was that it was the fan but it didn't seem to be overheating. It didn't seem hot and the fan kept whirring. It did however reach a higher pitch. I have an r7 250 btw and was thinking of upgrading anyway. I was going to wait but I want to know I if it is worth trying to fix if possible.
