So BIOS is in AHCI mode. Do you know if it always was?

Do this in recovery environment ->"command prompt" (whre you did diskpart and chkdsk as well)

Code:
reg  load    hklm\win7sys  C:\windows\system32\config\system
reg  query   hklm\win7sys\select  /v  default
reg  query   hklm\win7sys\controlset001\services\msahci  /v  start
reg  query   hklm\win7sys\controlset001\services\pciide  /v  start
reg  query   hklm\win7sys\controlset001\services\atapi   /v  start
reg  query   hklm\win7sys\controlset001\services\iastor  /v  start
reg  query   hklm\win7sys\controlset001\services\iastorv /v  start
reg  unload  hklm\win7sys
Is value of SELECT 1?
Which have start value 0?

I have no reason to belive that BIOS has changed however in my war with the rootkit it may have been changed. I personaly have not touched anything in the bios and dont think have have updated it recently>

chkdsk/f c: came up with no bad sectors and found no problems. However it "failed to transfer logged messages to the event log with status 50"

Will try those lines now.
