@Maintenance
After having read all your posts it seems to me, that you may only have updated the OS, but never done a clean OS installation since Vista times. If my impression should be real, it would have been a very big mistake and may explain all your troubles.
Here is my statement to your last post:
- Your used “Switch from IDE to AHCI” and “RAID to AHCI” tools cannot have the desired effect for your system, because your mainboard’s NVIDIA nForce chipset doesn’t support the AHCI protocol at all (as already written above).
- All Microsoft Operating Systems from Windows XP have the generic SATA IDE driver named PCIIEDE.SYS in-the-box (but with different versions and properties). Provided, that the system drive (SSD or HDD) is connected to a NVIDIA nForce SATA port running in IDE mode, there is nothing to load at the beginning of the OS installation - the OS own IDE driver will be automaticly installed and the related IDE Controller will be listed within the “IDE ATA/ATAPI Controllers” section of the Device Manager as “Standard Serial ATA Controller”.
- Regarding the TRIM support it is not enough to check, whether the TRIM command has been sent. Much more important is the question, whether TRIM has been arrived within the SSD cells. Neither NVIDIA’s SATA AHCI Controller (of newer nForce chipsets) nor NVIDIA’s SATA RAID Controllers let the TRIM command pass through. If you want to know whether your SSD is continuously TRIMed, I recommend to run the “TrimCheck Tool”. You can find the related download link and the guide within the start post of >this< thread.
