Hej igen
Har lige kigget på MSI PM8M3-V på:  
http://www.msicomputer.com/product/p_spec.asp?model=PM8M3-V&class=mb  
og der er SATA Controllere integreret i dit Chipset:
On-Board IDE  
• An IDE Controller on the VT8237R chipset provides IDE HDD/ CD-ROM with PIO, Bus Master and Ultra DMA133/100/66 operation modes. 
• Can connect up to four IDE devices. 
• Serial ATA 150 controller integrated in VT8237R  
• Up to 150MB/s transfer speed  
• Can connect up to 2 Serial ATA drives  
 
Har du installeret alle drivere ?
Har du nogle gule tegn i Enhedshåndtering ??
Der burde under IDE ATA/ATAPI controllere stå en: VIA Serial ATA controller
