I bought a graphics card in February a Sapphire 900pro SE for use in a friends machine its been working fine up until now, ive tried it in 2 different machines and its all connected etc but the fan on the card is not spinning and the graphics wont initialise on either machine and i get the respective error beeps for the motherboards. What can i do now? Can I take it back to the shop where I bought it from and legally claim a refund or do I need to check the manufactures warranty? It’s the first time I have ever bought that’s broken on me and im not sure what to do next. cheers
