Because my hdd seemed to be working itself to a frenzy when running Flight Simulator giving me random stutters that seemed to be drive connected ie flying along and everything stops for a second or two, I decided to see if AHCI would help the situation - well needless to say after a bios change to AHCI I got a big blue flash and nothing on reboot. After frantic forum searches I found the microsoft procedure for editing the registry. I found that my registry contained both IastorV and Msahci. I had to change both to zero for the system to boot.
Rereading the procedure I realized it was alluding to either Vista or WIN7 and that is why it instructed to click on ONE of the following registry subkeys..... . My WIN7 is an upgrade from Vista and I'm thinking the upgrade doesn't remove all unnecessary registry entries and I had IastorV left over from Vista. So, I'm going to the registry and delete the IastorV entry. Anyone think that's a bad idea? It seems like redundancy to me and wopuld only slow the system down while it sorts out which registry entry to address.
