I recently purchased 2 Samsung SSD 850 EVO drives and installed one in my computer and another in my friend's. I have done nothing differently for the installs, and my computer was actually in much better condition than my friend's before I started. After finishing, his computer is running smoothly and perfectly, and mine is not. I have put a lot of research and time into this and am coming to the community in the hopes of support. Any window I open not only takes at least 4 second to appear, but when it does usually all I can see for a few seconds is the outline. Once it has loaded, it is fine as long as I don't touch anything but if I try to move any window it ghosts. I am unable to play games due to the lag in system responsiveness as well. I have tried installing 3 times now and the same problem has occurred each time. I'll list what specs I know in hopes they might help, Thanks in advance for any help you can offer!
