*FAULTY* ATI Radeon HD5770 +

I am selling this as faulty as it just will not work at all for me in my machine and I cannot figure out the fault. It was working perfectly fine in my old machine but not my new one and still works in the old machine so I am having to sell this as faulty as it may or may not work in your machine and could indeed have some sort of fault. Please be aware I will not accept any returns/refunds for this. Thanks.
