I cloned my drive to a Samsung 850 EVO, then replaced the old drive with the SSD. It would not boot or even POST up. I put the old drive back in again and still it will not boot or POST. Just a single beep is all I hear. I tried replacing the SATA cable already. Diagnostics Lights 1, 2, and 3 stay on Fans run, light on motherboard is on.
 
Diagnostic code with the lights 1 2 and 3 means it is trying to start video card. Try reseating it/changing if it you have to.

Also unplug power cable, hold down power button for 30 seconds, and then let it set for 10 minutes as well WITH POWER CABLE UNPLUGGED. This will clear the memory and everything. You will be surprised how much that fixes issues.
