We’ve spoken a lot about SSD drives on the show recently. One thing I highly recommend with modern SSD drives and Windows 7 (or even Vista) is enabling AHCI in the system’s BIOS. Unfortunately when you do this on an existing install of 7 (or Vista) you are likely to receive a BSOD for your troubles. Fortunately there is a fairly easy fix from Microsoft  if you know where to look for it: – http://support.microsoft.com/kb/922976.

If you have already switched and are getting the BSOD you can switch back to IDE and apply the fix in the link.

  1. This is a golden tip. Thanks Garry. I have yet to make this change, my ssd is still in IDE mode and I need to make this change. I thought it was another reinstall and a complex one at that as my optical disk is also on sata so I cant even boot from the install disk without this error. I would need to create a bootable USB drive and then load the amd ahci driver so I keep putting if off not to cause the family loss of tv. With This I should be able to make if happen, Does windows then enable trim etc or do I need to do more regedits.

    Thanks Mark

  2. Just an update on doing this. At first attempt this did not work for me, however I then updated my BIOS to the latest version and on restart windows booted. So far the responsiveness seems much better. Thanks Garry you saved me another reinstall.
