Hello,

I made a conventional HD upgrade to 240GB SSD Kingston Now v300. The Mavericks OS so far everything perfect. But when I upgrade to Yosemite and used it for about 5 months and then the system was too slow and crash. I did not use the Trim. I tried reinstalling but hangs in the installation process. Mavericks also tried installing with OS 10.9.5 and 10.8.5 Lion OS, the situation is the same. Total system slowdowns, including the installation itself is very time consuming.

Any solution?
