Macbook restarts because of kernel panic

Since a year ago my Macbook Pro (13-inch, late 2011, El Capitan) restarts and shows panic reports. I changed the hard drive and installed a Samsung SSD. Lately, the kernel panics are more frequent. Also, it doesn't startup/boot properly at times. I formatted the SSD and repaired the SSD with apps such as DiskWarrior. The panic report says:
