thinkpad x260 laptop i7 could not even format it or do anything to it

hello, I just got a quick question. I have just received a ThinkPad X260 i7 CPU 256 SSD hard drive. I just removed the 256 SSD hard drive and replaced it with 1 terabyte hard drive and try to download some games on there and it kind of crashed my hard drive and I could not even format it or do anything to it just got locked up and it doesn’t even show up in the task manager or partition the hard drive with paragon software . it’s that true that thinkpad x260 can’t be playing games on the laptop. and also I did replacing the thermal paste on the heat sink fan. Is it just normal still kind of little hot on the laptop . when i received and play around with it alittle and it does gets hot on the left side thank you .
