hello guys I just want some help with my new lenovo y50 gtx 860m 4gb gddr5 !!! I bought this laptop a month ago or maybe more I don't remember, anyway I just had this serious stuttering freezing issue with almost all my video games and software editing apps I just noticed that my hard drive is operating almost 100% when I feel the stuttering begins and I disabled the antivirus and all background settings and I put it on high performance power plan and even with Razer game booster it didn't work . and I reinstalled my windows 8.1 just to make sure it's not the OS fault but after reading another threads I saw that its actually the HDD fault it acts like crazy all by itself !!! my question is if I replace my 1tb sshd 5400rpm with a better 1tb 7200 rpm does this fix my problem ?!
