Anyone run into similar issues like me with more than one machine. I frequently buy Dell Optiplex 960's on eBay and stick a Crucial SSD drive in it to run Windows 7 x64. It seems that this past year, I've been encountering some problems with this combination. Either when the machine is first turned on it'll say "No boot device available" or it'll Blue Screen on the user while they're working and it'll just crash and then on reboot say "No boot device available" as if the drive disconnected itself while everything was running.
The fix is to reboot a few times and eventually it works again. Sometime is runs for months with no crashes, but lately one machine has been crashing twice a day.
I can get you more specific information like BIOS Firmware version of the Dell and specific info about the Crucial drives I use. For now I'm hoping someone has had a similar experience and has a fix for it.
