Do you get into windows?
If you can and your motherboard chipset is via then go to the windows update site .... I believe there is a fix for this.... also have you installed the motherboard drivers yet?
It may also be worth running chkdsk open My Computer, right click the drive, and choose Properties. On the Tools tab, click the "Check Now" button. Check either or both (I usually check both) boxes, and click Start. If the disk contains locked files, CHKDSK cannot run immediately, but will ask if you want it to run at the next reboot.
