2700k, asus p68gen3, intel670
The machine runs for a couple weeks, and then locks up. Six iterations so far.
Nothing will dislodge it, not even repair or Acronis disk.
The people who built it have taken it apart and put it back together. No change
But take the Crucial SSD and put it in another machine - it works fine.
When it locks up, it gives an A2 (IDE detect fault) error notice on the motherboard.
Is there anything to be done short of reinstalling Windows, which will wipe out FSX?
And will reinstalling Windows even fix it?
Any help would be very much appreciated.

Usually A2 error has something to do with your motherboard having issues detecting drives. I would try removing every device that uses SATA and only connect the one SSD.

 

If the SSD being the only device plugged in fails to boot, I would try replacing the SATA cable.

 

Also, make sure your SATA is configured as AHCI and not IDE in the BIOS. Switching from IDE to AHCI usually requires a fresh install of Windows, but there are ways around that

 

You could also try updating your BIOS to the latest version.
