I installed the Intel SATA Raid driver
from Gigabytes website but the problem still persists, Video card has latest driver installed, Enabling AHCI gave a slight boost in performance according to HD Tune & Passmark's Disk Mark but nothing to significant, I may switch back to IDE mode or just remove the IDE hard drive from the PC altogether.
I didnt use any fixes to enable ahci instead I moved the boot drive to a gigabyte sata port and then enabled Intel ahci in bios, booted Windows 7 (which detected and installed the Intel achi driver), then shutdown and moved boot drive back to Intel sata port.
but speaking of fixes I *did* install this hotfix
after installing Windows 7 service pack 1 because my PC wouldnt wake up from sleep properly (it was shutting down entirely instead of sleeping) the hotfix worked and didnt have any issues with drives waking up etc. everything was normal until I enabled AHCI, I'm curious if there's a conflict between the hotfix & enabling ahci.
