SSD runs slower after I reboot

[Gamer Haq]

I am having some problems with my SSD. It's running at its normal speed right now but when I restart windows the SSD runs really slow at a 10% of the speed it was running before. I tested using AS SSD Benchmark.
The SSD is: Crucial MX300

Do you mean it slow at the beginning then back to normal speed?
how full? what the usage at the beginning ?

No, it doesn't go back to normal speed, I have to power off the system completely and turn it back on for it to go back to normal speed. Forgot to mention this part. And it's not my motherboard since my HDD runs completely fine. I also changed the SATA cable I was using for the SSD. This happened when I upgraded some of my components.
