hey guys I need your help.last week I got a 500gb hard disc and it worked great.but today all of a sudden my pc started to block up.Sometimes i can't enter windows at all and sometimes my whole pc blocks up when i do something.I thought it was the hard disc so I disconnected it and left my other hard with my windows on it. my other hard that i had in the pc works great.no lag or any blocking or stuff like that.how can i fix this problem.I want the 500gb hard to work normally because I need the space.Can anyone help me? o and I did not install windows on that hard so only my games and other stuff are on it so it could not be some software problem could it?
