Okay I recently installed a new video card. When I installed it I had to move a USB PCI card to the bottom PCI slot. I reformatted the hard drive and reintalled windows. When I look in device manager there is a yellow exclamation point next to SCSI and RAID Controllers----Nvidia NForce(tm) ATA RAID Class Device. Under the properties it says that the location is unknown and "the device is not working properly because windows cannot load the drivers for this device." The driver version is 5.10.2600.446. I have never had any exclamation points in my device manager before. Any ideas of how to get rid of this thing????
