what if components burnt on their PCB due to their manufacturing or handling failures?
i can understand them refusing if you've modified the board, but some of those burns could be their mistakes.
We're not talking exploding capictors, we're talking itty bitty chips that go boom.
Theres no way the psu should be supplying enough volts to let those chips explode. Most likely lightning or dodgy psu. Im not saying its impossible.
I doubt they just glance at the card, glance at the page and find a quick and easy way to rule you out of your warranty... they probably rule out their own voltage regulators first, and once they know it wasn't their fault, they then think about not giving warranty.
Besides... Gainward are the guys that "mod" their Pci-Ex card to AGP ala 7950gt AGP, give em some credit.
