Ralith,
You said you have an MSI P6N, correct? That board uses an NVIDIA 680i chipset, right? Do you have the nForce chipset drivers installed?
Assuming you answered yes to all of the above, follow these directions (
for directions involving the Control Panel, make sure you're using Classic View):
1. Download and install
Driver Sweeper.
2. Go to
Programs and Features in the
Control Panel and uninstall all
NVIDIA drivers (other than the display driver).
3. Reboot the computer. While it is rebooting, boot into safe mode by tapping
F8 while the computer is booting and selecting
Safe Mode.
4. Run Driver Sweeper. Check the box by
NVIDIA - Chipset and hit
Clean. Once it is finished, close the program and restart the computer, this time regularly.
5. Go to
Administrative Tools in the
Control Panel and select
Device Manager.
6. In the
Device Manager look under the
Storage Controllers,
IDE ATA/ATAPI Controllers, and
SCSI and RAID Controllers sections for any entry called
Nvidia SATA controller (or something similar). Uninstall all of these by right clicking on them and selecting
Properties, then selecting the
Driver tab, and finally selecting
Uninstall Driver.
7. After you have uninstalled the drivers for all of the
Nvidia SATA controller entries (after you uninstall one, the rest may disappear, in which case you don't need to do anything else), restart the computer.
And that's all there is to it. Let us know if this helps with your problem.
