The PC i currently use is a Lenovo Thinkcentre Edge 71, the hard drive in it is currently failing, (7k Hours Used, but pc is second hand from ebay, Checked using crystaldiskmark) games have become unplayable, even games such as fortnite, h1z1, CoD, I'm only able to surf the internet and open up basic programs.. i have a replacement seagate barracuda 1tb 7200rpm being delivered, how would i be able to transfer all my data (400gb) of games and videos and OS over to the new drive? i figured because this system is OEM there would probally be a level of diffuculty that comes along with it..
