User log in problems

[LiveLife10]

Hello,

I just re-installed my OS X Yosemite and I am having lots of bugs with the OS I never had before.
Most of the time when I wake up my computer and try to log in the log in screen freezes and I must restart the computer manually...
And when it decides to work then it works very slowly and in a huge delays.
How can I fix all this?

Thank you very much

Same Issue

I have had a similar issue... when the computer goes to sleep and I fire it back up, it takes me to the login screen. I type in my credentials and it goes nowhere. The background apps are still working and I get notifications but I cannot actually get back to my desktop. Often, I end up having to restart the computer, which is a big pain.

My temp solution is to install 'caffeine' so my computer doesn't sleep, but that's not a good solution considering I'd rather it default to login for security purposes.

Help!
