Hi all! I just purchased a Gigabyte R9000 Pro for my wifes comp. Seems that every time the comp is rebooted, there is a bios beep, and i get a message saying that the configuration has changed or the bios batt needs to be replaced. I put her old GeForce card back in, and no problems. It is a Compaq PC, with an i850gb chipset. Anyone ever hear of any compatibility issues on this?
