A month ago I bought a Sapphire 7970 OC with boost (http://www.newegg.com/Product/Product.aspx?Item=N82E16814202008). I put it into my computer and it worked fine for three days then started to randomly freeze. The freezing started when viewing windows media player videos the screen would go fuzzy but the audio was fine. The only way to stop this was to unplug the computer. Then it started to randomly freeze regardless of GPU load. I contacted sapphire support and they said to RMA it. So I did. Then I got the new card and it worked great for three days. Then it started freeze again in the same way it did before. I took it out and put it in a different PCI-E lane and it worked for three more days. Now it doesn't work at all and freezes my computer within 15-30 minutes of use. I don't think it is my other computer components because my old graphics card works fine. Sapphire support says i need to RMA it again. Does anyone know what could be wrong with it?
