I recently bought an used Lenovo ThinkPad L450. This last days it started doing this weird thing when it randomly freezes and than after some time it un-freezes. I think that its the problem with the SSD because from what i can see from crystaldisk info its been really heavily used ( 22263 GB of writes and 50930 power on hours) . I did a memtest and it showed no errors. I'm just concerned that the chipset might be failing. How likely is the chipset to fail? I'm not sure but i wanted to check before i buy a new SSD. What do you guys think?
