MacBook Pro freezes but mouse moves
Hello,so i just upgraded the HDD on my MBP4,1 from Momentus 5400.5 to Momentus XT 500GB, since this PC has sata 1.0 i don't think it would work.so after i installed Yosemite (because i have 2GB RAM and EL Capitan would probably make it slower by 50%) but after 7-12 Minutes of usage it freezes i can use the mouse just move it
Right click works but left click doesn't..
Please Help
