I’ve recently transferred games and other programs to a new HDD. I haven’t touched Windows or anything I didn’t know how to transfer safely. Now all of a sudden my pc is freezing, restarting, disconnecting from monitor and running games at 4 FPS. And I am clueless as to why. I’ve tried reinstalling graphics drivers, checked for viruses and checked all fans are working and everything that should have a light on has a light on. Please help
