Hello, over a couple of months i have bought a lenovo y50-70 touch, i loved the gaming laptop until when i started playing games like Black Ops 3. Most of the time the problem was with gta 5, but basically when i start playing games my CPU which should run at 2.57 Ghz starts running at about 1.77 Ghz, can anyone help me with this or does anyone know the problem and a solution. Also i have a problem with my hard drive and have been wondering if i should updrade it because it seems that this hard drive is starting to run slow and when i look to see how much is being used when i am playing games it says there is 99% to 100% beeing used. I am not sure if this is because it is a 5400 RPM SSHD but i did a little research and people said it does not matter with sshd's abut i am not sure because i am new to this so. But overall i am just trying to figure out if i should upgrade to a 7200 RPM SSHD or not, ps they both have 8GB of the ssd. Thanks for helping!
