Up until now this machine has been flawless aside from a harddrive failure last year, at which point I replaced it with an SSD. However over the last month or so it has been crashing on a regular basis (sometimes multiple times in a day). The screen freezes aside from the mouse, and no amount of time or attempts to force quit will help so I have to manually restart. Sometimes while my computer is in sleep it will just randomly reboot. It's not the end of the world since I mostly work in Photoshop which can recover work. But it is very annoying.

Any ideas what could be going on? I was hoping to wait until the next iMac Retina update before upgrading my machine.
 
Random thoughts:

- Loose drive connection (to cable)
- Loose cable connection (to motherboard)
- RAM (is the RAM original or replacement?)
- Something else disturbed (connection, etc) when you replaced drive
- Video card failure?
