I put a new system together about six months ago with all new parts. From the first week i have had lockups when playing games. These lockups were relatively rare at about once a week or so. I have tried lots of different drivers, the later ones being the worst. I was living with it, being so occasional, but it seems to be getting worse now and its having odd effects on the pc, like slowdowns, and hanging when shuting down. I have now put my old proven 8800gt back in, and even though its early days, seems a lot more stable. My question is if i send the 260gtx back to Leadtek under their 2 year warantee with this occasional fault, are they just going to plug it in and say its fine and send it back to me at a cost.
