OK I will follow your advice, One more thing, to make it clear, my read speed atm is 250/s almost same when i got the SSD but the write speed is where i have problem, because my write speed was 150-180/s and now its 50/s max, even my HDD has write 50/s so i dont know if you get my point but something is wrong with the write speed, i didnt had ahci before nothing was the same pc same memory same vga, I had to make format my SSD and put new windows up and from that time everything get worst.. PS: thank you for your patience man.
