Hi,
I had the same problem, and i thought that was the SSD but the problem was the "core parking".
In my case i solved it in this way:
Open Regedit
Find:
"0cc5b647-c1df-4637-891a-dec35c318583", ValueMax "Change" "64" to "0"
F3 to search the next, one for energy plan that you have in your machine. All of them change 64 for 0
Find:
"ea062031-0e34-4ff1-9b6d-eb1059334028" "Change Attributes" "1" to "0"
F3 to search the next, one for energy plan that you have in your machine. All of them change 1 for 0
I hope that it helps ;)
